An architect is designing a multistory office building. Which design strategy represents a successful integration of a building system with the project design?

A light shelf along the south facade Correct. Building integration is the organized consideration of the interrelationship between the productive systems of a facility for the purpose of optimizing the effectiveness of the collection of systems. A light shelf represents a successful integration of the building system since it integrates well with the building lighting, glazing and HVAC systems. It reflects light deeper into the building, thereby providing more light in the interior. It blocks excessive light and heat from entering spaces close to the perimeter wall. A "sandwich" system for the ceiling plenum Incorrect. Most multistory commercial buildings are very wasteful of the space above the finished ceiling and below the floor of the level above. This is the "sandwich" volume for various building systems such as structures, HVAC, electrical, communications, plumbing, and fire protection. To make the design process simpler, each system is given its own layer, allocating an independent volume to each of the systems. The design process thereby becomes more like volume allocation, rather than building system integration.

A new three-story building is being designed in the western United States. The client was hoping to build with masonry to achieve a historic look, but has been convinced to use steel for its structural properties. A steel-framed building can better withstand the effects of an earthquake over a masonry building due to which property?

Ductility Correct. The unique structural property of steel is its high ductility. This refers to the elongation that a material can undergo after it has yielded or exceeded its elastic range. Steel has a long range of ductile ability in which it can be subjected to higher and higher stresses without failure. In good seismic design, structures should yield in order to absorb and dissipate energy. Ductility in seismic design applies to the structure as a whole, as well as the members and connections. Strength Incorrect. Strength measures how much stress can be applied to an element before it deforms permanently or fractures. Strength of a material can refer to either yield strength, ultimate strength, or fracture strength. A material can be strong without being ductile. A steel wire is very strong but will break suddenly.

During the design development stage of a regional airport project, an architect notices a spatial conflict between a return air duct and several light fixtures serving the main entrance. How should the architect determine the best course of action?

Have the HVAC consultant redesign the duct Correct. The most efficient and design-conscious approach is to adjust the return air. This could result in the rerouting or resizing of the duct, or shifting to a return air plenum. Since return air is not hampered by corners or turns, it simply needs negative pressure to reach its destination. As the light fixture serves a lobby space, it is likely integral to the design, and would involve more work to adjust. Have the lighting consultant redesign the lighting Incorrect. As the lighting serves the main entrances, the location of the light fixture should take priority.

The client wants an efficcient heating system to help minimize cost. Which of the following heat sources could the architect recommend?

For RTU-2, the dampers are placed in each of the 14"x10" lines in order for them to be controlled separately.

What is the difference between pre-stressed, pre-tensioned, and post-tensioned concrete?

Most precast, prestressed concrete is actually pre-tensioned-the steel is pulled before the concrete is poured. Post-tensioned concrete means that the concrete is poured and then the tension is applied-but it is still stressed before the loads are applied so it is still prestressed. Pre-stressed is squeezing concrete together. Pre-tensioned (such as precast concrete) and post-tensioned (such as cast-in-place concrete) are categories of Pre-stressed concrete.

WHen do you use a two way lab?

Typically when the area being supported is square The Building Structural Standard defines a two-way slab system as a concrete slab system in which two rebars are arranged in two directions regardless of the presence or absence of a beam that transmits a load to a column'.

An architect is planning a new auto mechanic shop. The shop will have two repair bays, a storage area, and a small office. The building will be 1,000 square feet. The building is to be categorized as the least possible fire-resistive construction type. Which construction type is both appropriate and minimally fire-resistive?

V-B Correct. Type V-B construction is unprotected wood frame. This type has no fire rating requirement, making it the most combustible. It is appropriate for the auto shop because there are multiple occupancy types and the square footage is low enough to fit within the building area requirements of Type V-B construction. V-A Incorrect. Type V-A construction is protected wood frame. This requires the structural framing, bearing walls, floor, ceiling, and roof to have a one-hour rating. III-B Incorrect. Type III-B construction is unprotected combustible construction with brick or block walls. The exterior walls need to have a two-hour rating.

A set of plans is designed for a cold climate. A builder wishes to build the same structure in a warm climate. Some of the details will need to be modified to account for the change in the climate. What building material should the architect relocate within the wall section?

Vapor retarder/barrier Correct. Vapor retarders (or vapor barriers as they are sometimes called) are placed in the wall on the warm side of the insulation. This means it goes on the inside, in a cold climate, and on the outside, in a warm climate.

The owner of a proposed three-story office building would like their architect to design the building so that it will receive LEED Gold certification and meet their specific energy usage goals. While the architect cannot guarantee this, they explain to the owner that if the building is built in accordance with their drawings and specifications, it will be capable of obtaining the desired certification and meeting the energy usage goals. Which of the following factors that occur after design completion could affect the achievement of these sustainability goals?

Value engineering Correct. Value engineering by the owner or contractor to reduce costs during construction can have an impact on overall building and systems performance and certification. The architect should notify the owner and contractor of performance or certification issues that could be a result of proposed changes to the drawings and specifications. Certification approval Correct. LEED certification is not guaranteed. Various elements in the final construction and submitted documentation could affect whether certification will be awarded, or what the level of certification will be. Building systems operation and maintenance Correct. When energy usage does not meet specific goals, it is often caused by the owner not operating the building systems as they were designed to be run. Contractor documentation Correct. The contractor must accurately compile the required documentation during construction that will be submitted for LEED certification. If the contractor fails to provide this information, the building may not be certified. Permit approval Incorrect. Receiving a building permit should have no impact on the building meeting sustainability goals, unless the authority having jurisdiction (AHJ) requires revisions to the drawings that will impact those goals. In that case, the architect can try to make revisions that will still be in line with the project goals if possible.

In order to gather information about community concerns regarding a new proposed senior living community, an architect has decided to host a design charrette. The project is privately funded and will use design-build contracts. Throughout the charrette, the architect receives a lot of feedback; some is actionable and some is not. Which of the following responses should the architect consider as relevant regarding the proposed project?

"I'm worried about using my wheelchair to get from my car to the building." Correct. This concern addresses site accessibility. The architect should consider accessibility along the entire path of travel, not just inside the building. "How are we going to address issues of aging in place?" Correct. "Aging in place" is a concept which addresses the ability of a building to accommodate and plan for different levels of accessibility as an occupant ages. This concern should be considered in the design of the new senior living facility. "Will the building be visible from Main Street?" Correct. The architect should consider how the building sits in its surrounding context, including from surrounding thoroughfares. If visibility is a community concern, it's important to address it during the design process to avoid potential backlash from the community in the future.

An architect is designing a new 1,200-square-foot house with eight-foot ceilings. The initial design calls for five 3' x 4' windows that allow 60 cfm of fresh air each. However, the local sustainable design ordinance requires new houses to provide three fresh air changes per hour. How many additional 3' x 4' windows are required to comply with the ordinance?

3 CALCULATIONS 1. House volume: 1,200 square feet x 8 foot ceiling height = 9,600 cubic feet 2. Cubic feet per hour required by ordinance: 9,600 cubic feet x 3 fresh air changes per hour = 28,800 cubic feet per hour 3. Cubic feet per minute required: 28,800 cubic feet per hour / 60 minutes per hour = 480 cubic feet per minute 4. Cubic feet per minute provided by five windows: 5 windows x 60 cubic feet per minute = 300 cubic feet per minute 5. Cubic feet per minute deficit: 480 cubic feet per minute required - 300 cubic feet per minute already available = 180 cubic feet per minute still needed 6. Additional windows required: 180 cubic feet per minute / 60 cubic feet per minute (each window) = 3 windows Topic: Project Integration of Program & Systems

A municipal airport terminal with a gross area of 200,000 sf utilizes a variable air volume (VAV) central HVAC system. How much area should be allocated for all components of the HVAC system?

6,000 square feet Correct. VAV systems are a subset of all-air HVAC systems. All-air systems need about 3-9% of the gross building area for the HVAC system, depending on the building size and program. A good rule of thumb is large buildings (>50,000 sf) set aside 3% of the gross area for HVAC systems, midsize buildings (between 5,000 sf and 50,000 sf) set aside 6%, and small buildings (<5,000 sf) set aside 9%. Since the building is large, taking 3% of the gross area would result in 6,000 sf designated for the HVAC systems. (200,000 square feet x .03 = 6,000 square feet.)

The trust that owns a historic bank property is looking to add a green roof to the existing flat-roofed building. A preliminary feasibility study determined that the addition of the green roof would not be visible above the existing parapet, and would require only minor structural work in adding metal plate reinforcement to the existing exposed wood beam structure. The trust has hired an architect to evaluate the approach in line with the standards and best practices of historical rehabilitation. Per the Secretary of the Interior's Standards for Rehabilitation, what would be the best recommendation for the green roof proposal?

Advise the client to investigate alternatives that will not require structural changes Correct. Since the wood beams are exposed, they are considered a historic element, and adding reinforcement would alter the historic nature of the property. Due to the existing structural constraint, the architect should advise the owner to explore alternatives to avoid damaging the historic nature of the structure. Advise the client to proceed and add additional wood beams mimicking the original wood beams, in lieu of metal plates Incorrect. This is not a recommended approach as it would alter the historic nature of the property. Historic mimicry is primarily recommended for replacement of severely deteriorated elements, and is not a recommended method for additions or alterations.

Staggered electrical outlets within partitions so they are not back-to-back Correct. Back-to-back outlets provide potential openings for sound transfer and should be avoided. Acoustical sealant at the junctions where walls meet ceilings and floors Correct. Providing airtight construction will reduce sound transfer. High-mass materials such as solid concrete for the wall construction Correct. High-mass construction is better at reducing sound transmission. This is because sounds are vibrations and high-mass materials will not vibrate as readily. Hard gypsum board ceiling and sealed concrete floors Incorrect. Limp materials provide better sound reduction than stiff materials.

An architect is in the programming phase of a tenant improvement project for a small university office suite in an existing building. The client has asked for five 120-square-foot offices for staff members, a 200-square-foot conference room, and a 100-square-foot storage room. The client has a limited budget and would like to minimize the area to be remodeled. Other programming requirements follow: Use a building efficiency ratio (net-to-gross) of 0.75 if a double-loaded corridor design is implemented. Use a building efficiency ratio (net-to-gross) of 0.70 if a single-loaded corridor design is implemented. At least two offices and conference rooms should be located along exterior walls for views. The dimension of the longest length of existing space to remodel is 50 feet. How much area is needed for the renovation? _______ square feet

Correct answer: 1200 CORRECT RESPONSE 1,200 square feet A double-loaded corridor design should be implemented to minimize the area that needs to be remodeled. CALCULATIONS 1. Total office area: 120 sf x 5 offices = 600 sf 2. Total net square footage: 600 sf (offices) + 200 sf (conference room) + 100 sf (storage room) = 900 nsf 3. Gross square footage needed: 900 net sf ÷ 0.75 efficiency ratio = 1,200 sf Section: Project Integration of Program & Systems

An architect is designing a new nature center. A large, paved plaza in front of a multi-vehicle drop-off area is being planned at the main entrance of the project. What key considerations should the architect make when designing the plaza?

Designing the plaza in a way that will allow runoff to be collected in a constructed stormwater wetland Correct. Constructed stormwater wetlands are designed to resemble natural environments and would be appropriate for the nature center. Utilizing a rigid paver system Correct. Rigid paver systems effectively shed water when installed correctly. Utilizing a rigid paving that collects water and then flows to a swale or stormwater wetland is a common solution to stormwater management. This system allows for a high level of control in terms of where water goes when it rains. Providing stormwater collection tanks under the plaza Incorrect. This strategy is often used for large parking lots when no other method of stormwater control is possible. Integrating a detention basin into the plaza design Incorrect. A detention basin holds large amounts of stormwater runoff and is unlikely to be allotted such a large area in an entry plaza.

An architect is designing a replacement roofing system for an exiting building in a hospital complex. The hospital is worried about the effects of the installation of the roof on patienets with breathing difficulties. The hospital has asked the architect to choose a roofing system that minimizes health risks. Which roofing system should the architect specify?

EPDM EPDM membranes have a minimal amount of seams which are joined together with adhesive. This roofing system is the most appropriate option because it is the only system that will not pose a risk to the health of hospital platiemnts during isntallation. patients

What is an EPDM roofing system?

EPDM is an extremely durable synthetic rubber roofing membrane (ethylene propylene diene terpolymer) widely used in low-slope buildings in the United States and worldwide. Its two primary ingredients, ethylene, and propylene, are derived from oil and natural gas.

An architect is designing a new subdivision on a large plot of land adjacent to a commuter train route. What is the most effective option for mitigating off-site noise intrusion from a nearby train route?

Earthworks to block sound Correct. The best approach is to adjust the grading to deaden the noise. Construct sound barriers Incorrect. Sound barriers do not have enough mass to effectively deaden the noise from a train route.

The design of a new skyscraper has multiple floors below grade. The second level below grade will have restrooms and a staff room for the maintenance team. This level will be below the main sanitary sewer to which the plumbing fixtures must be connected. Which of the following plumbing elements must be included in the design

Ejector pump Correct. An ejector pump looks similar to a sump pump, but its job is to collect sewage from the basement plumbing that is lower than the municipal sewer line and pump it up and out. The ejector pump is in a pit in the ground, like a sump pump. It has a lid and is vented. Sump pump Incorrect. A sump pump is not for use with sewage. Sump pumps are for pumping groundwater from the drain tile piping or for pumping water out of the basement.

A university has mandated that all new campus projects must achieve LEED certification. Which method of energy calculation should be used by the project team?

Energy cost budget Correct. The energy cost budget method is used to verify compliance with LEED. It determines the energy budget for a specific building. The budget is calculated with a computer simulation of hourly energy use over the course of a year. Although it is a complex method, it is the only way to deal with individual projects and the unique aspects of a design. Building area Incorrect. The building area method provides a maximum allowable power in watts per square foot of building area, based on the building type. This may be used to meet several code requirements. However, it is not the prescribed method for LEED certification, which requires energy modeling.

Although it is a complex method, it is the only way to deal with individual projects and the unique aspects of a design. Space-by-space Incorrect. The space-by-space method assigns allowable wattage per square foot to spaces based on their use type. When multiplied by the gross area of each programmatic space, a lighting power density can be determined and compared to the code requirements. However, it is not the prescribed method for LEED certification, which requires energy modeling.

The parts of a packaged unit HVAC system are listed below. In which stage of the refrigeration cycle is the refrigerant a gas under low pressure?

Evaporator Correct. The question is describing an evaporative process in which the refrigerant turns from a liquid to a vapor; thus the evaporator is the correct answer. Condenser Incorrect. The condenser is where the refrigerant turns back into a liquid.

What is a staggered truss system?

Everyone other floor is a floor, each truss is going to hold the floor below and above it. We could have column-free floor plates.

Fire wall Vs Fir Barrier

Fire Wall Most stringent-you essentially build two different buildings, structurally independent of one another. Separated two construction types or two different areas. Extends from foundation through roof Fire Barrier More commom-extends from floor to underside of structural ceiling and does not need to be structurally independent. Required fro mechanical shaft walls, egress stair walls, separated uses, and incidental uses. Fire partition Least stringent-can be mad out of wood and can include a dropped ceiling. (Doesn't have to extend to the deck above) Required for corridors.

An architect is developing plans for a new electric vehicle manufacturing facility. Early in the design process, the architect requests a meeting with the building plan reviewer to discuss the project and identify any concerns the reviewer may have before moving forward with the project design. In addition to the building plan reviewer, who else should the architect recommend attend the meeting?

Fire chief Correct. The fire chief would be a beneficial addition to the meeting as the building inspector and fire plan reviewer sometimes have different interpretations of the building and fire codes. Also, the fire chief may have additional concerns based on the current capacity of the fire department.

Which HVAC sstems are capable of both heating and cooling with the same units?

Forced Air Packaged Terminal Units (PTACs) Trough-wall units Heat Pumps Heat pumps can be reversible. They can pump heat out (cooling) or pump it in (heating)

What is a GFCIT plug?

GFCI stands for Ground Fault Circuit Interrupter. These are also referred to as GFIs, or Ground Fault Interrupters. A GFCI precisely monitors the balance of electrical current moving through a circuit. If the power goes where it shouldn't, like in a short, the GFCI immediately cuts off the electricity The NEC requires GFCIs on all exterior and bathroom receptacles (another term for outlets). GFCIs are also required on all receptacles serving kitchen countertops. In laundry rooms and utility rooms, GFCIs should be installed on outlets within six feet of sinks, washing machines, and water heaters.May 18, 2022

What is galvanic action?

Galvanic action occurs when two electrochemically dissimilar metals are in contact and a conductive path occurs for electrons and ions to move from one metal to the other. One metal corrodes as its ions are deposited onto the other metal

An architect is working on selecting an elevator for a new luxury high-rise apartment building. The elevator needs to be a quiet, high-speed, and energy-efficient system able to handle the day-to-day needs of the residents. Space is also at a premium within the building, so a machine-room-less system is preferred. Which of the following elevator types would be most appropriate given the requirements?

Gearless traction elevator Correct. While the gearless traction elevator provides the same performance as a geared traction elevator, a gearless traction elevator is quieter, more efficient, and does not have a gearbox, which eliminates the potential need for a machine room. Incorrect. While a geared traction elevator would be appropriate given its speed and height capabilities, the required gearbox is noisier and would require more space (i.e. a machine room) than the gearless option.

What is a girder, beam, joist relationship?

Girder- shorter span, beam -longer direction, joist-in between beam- decking-always laid in the opposite directio

Peak demand for cooling often coincides with peak demand for electricity. This results in a spike in electricity use when electricity is most costly. Which type of cooling flattens this curve?

Ice storage Correct. An ice storage cooling system uses energy overnight, when it is less expensive, to freeze ice. The ice is then used during the day to cool the building.

Hollow core slab Correct. A hollow core slab minimizes site construction time and allows for thin floor thickness. Post-tensioned one-way slab Incorrect. Post-tensioning does allow for a thinner floor slab thickness, but does not decrease the on-site construction time.

What is a Vierendeel truss?

noun. Vie·ren·deel truss. ˈvirənˌdāl- variants or Vierendeel girder. : an open-web truss with vertical members but without diagonals and with rigid joints.

An electrical engineer wants to look up the minimum required number of foot candles for interior artificial lighting. Where should they look?

IBC Chapter 12 addresses the Interior Environment. Note: Chapter 27 addresses electrical, the requirements outlined in this chapter are for general electrical supply and emergency and standby power systems.

Where do you locate your building on a hill? At the bottom? Partway up? At the crest?

If you are building in the mountains, know that the valley will pool sinking cold air on still nights (good for hot-arid) and the top will have the most wind (good for hot humid). So locate your buildings on the following elevations based on climate:

What is ballon framing?

In balloon framing, the studs (vertical members) extend the full height of the building (usually two stories) from foundation plate to rafter plate, as contrasted with platform framing, in which each floor is framed separately.

What is platform framing?

In platform framing, each floor is framed separately, as contrasted with balloon framing, in which the studs (vertical members) extend the full height of the building. Freed from the heavy timbers of the post-and-beam system, platform framing offers ease of construction.

What is the difference between A Shear Wall Connection and a Moment Connection?

In steel, you can recognize a shear connection because (generally) the beam web is bolted or welded to the column, but beam's flanges are not. Shear walk connections resist gravity, but don't do well in the presence of lateral forces like wind and seismic. Therefore they need additional lateral resistance from cross bracing or a shear wall. By contrast steel moment connections (generally) bolt/welded both the flanges and web to the column and resist both vertical f=gravity and lateral wind/seismic.

The owner would like to create typical live/work apartments consisting of one bedroom and one living room on the upper floors of the existing building. The apartments will each have 300 sf of open living space and 300 sf of bedroom space, excluding the bathroom and kitchen. The architect is verifying operable glazing requirements against the existing window characteristics. Based on the information provided, what is the area of operable glazing required per room to provide fresh air?

Incorrect - the answer is 15 The provided reference states that any habitable room must have glazing with an area no less than 8% of the floor area of that space, and must have operable window area totaling a minimum of 5% of the floor area of the space. The planned apartments will each have two habitable rooms that are 300 sf each. To determine the minimum operable area required per room, the area of the individual habitable space is multiplied by the minimum operable area percentage allowed:300 sf x 0.05 = 15 sf

A proposed two-story wood-framed building is 36'x48'. The architect is comparing costs for two different framing systems for the second floor. The first system is 18"-deep trusses spaced 24 inches on center. The cost of the trusses is $3.20 per linear foot. The second system is 16" wood I-joists spaced 16 inches on center. The cost of the I-joists is $2.50 per linear foot. The joists will span the short direction. Ignoring any cost differences due to increased building height and assuming all other factors are the same (including labor, fasteners, intermediate supports, and lateral bracing), what is the cost difference between the two framing systems for the second floor? Round to the nearest whole dollar.

Incorrect - the answer is 450 This is a unit cost comparison. First, figure out how many framing members are needed when they are spaced at 24 inches on center or 16 inches on center. Do this by sketching the building's footprint. The framing members will span in the short direction.48 ft x 12 in. / 24 in. = 24 + 1 = 2548 ft x 12 in. / 16 in. = 36 + 1 = 37 (An additional framing member has been added to each calculation above to accommodate the extra member required at one end of the building. This can been seen by sketching the framing members in the building's footprint.)The placement of trusses at 24 inches on center would require 25 members, and the placement of I-joists at 16 inches on center would require 37 members.Now calculate the price of each by taking the number of members x the cost per linear foot x the length (36 ft).Trusses:25 x 36 ft x $3.20 = $2,880.00I-joists:37 x 36 ft x $2.50 = $3,330.00Last, find the difference by subtracting. $3,330.00 - $2,880.00 = $450.00.

Incorrect - the answer is 586 First, subtract the salvage value from the initial cost: $22,000 - $1,500 = $20,500 Then, divide by the useful life expectancy of the system: $20,500 / 35 years = $585.71, which rounds to $586. The maintenance costs are irrelevant to annual depreciation calculations.

During a low-grade seismic event, the two-hinge moment-resisting frame depicted undergoes elastic deformation. What is the moment value at point B if the two-hinged moment-resisting frame resists a seismic force of 70 kips? Ignore the weight of the frame itself.

Incorrect - the answer is 595 Because the two columns are identical (e.g., there are two HSS12x12 columns), each column resists ½ of the total seismic force; so we divide 70 kips / 2 = 35 kips (this force will act horizontally upon the hinged connection at the base of each column). The height of the columns is 17 ft.Thus, the moment value at point B will be:M(B) = 35 kips x 17 ft = 595 kip-ft.

A proposed children's play area contains the following equipment: 1 sandbox 9 swings 1 spiral standalone slide 3 play panels 1 dome climber 2 diggers 1 playhouse How many of the above play items must be on an accessible route?

Incorrect - the answer is 7 The answer is 7. Scoping for play structures is found in the ADA 2010 Standards section 240.2. One of each kind of ground-level play feature (sandbox, swing, standalone slide, play panels, climber, digger, and playhouse) must be on an accessible route. See how there is a different between "accessible route & ADA usable"

Incorrect - the answer is 8640 Correct. IBC (2018) 1204.2 requires a minimum net glazed area of 8% of the floor area. The total area of the two rooms is 750 sq. ft., and 8% of that would be 60 sq. ft. (8,640 sq. in.). There are 144 square inches in 1 square foot. To convert from square feet to square inches, multiply your figure by 144

An architect is designing a building in a cold climate and wants to eliminate condensation on the interior surface of the building's exterior wall. Which of the following will help eliminate condensation?

Increase the wall insulation Thermal insulation will help to reduce the amount of heat lost from a building and raise the internal temperature of the wall near the interior surface. Lowering the interior relative humidity Lower humidity will result in a lower dew point for the air within the space - thus lowering the chance of condensation Raising the surface temperature of the affected area Increasing the surface temperature will reduce the cooling of any moisture-laden air and, consequently, the amount of condensation.

An architect is working on a project in an unfamiliar location. Where should the architect look to determine the climate zone of the project site?

International Energy Conservation Code (IECC) Climate data for building science is found in the International Energy Conservation Code. These maps are used to determine the climate zone for designing building envelopes and mechanical systems in buildings. The USDA ZOne map is incorrect. This map is the standard by which gardeners and growers can determine which plants are more likely to thrive at a location.

An architect is designing a passive solar building which will take advantage of an adjacent south-facing slope. The slope will have a specially designed collector where air will be warmed by the sun and then rise to serve as the heat for the building. Cooler air will simultaneously be pulled from a chamber below the floor, creating a convection loop. How is this type of passive solar system identified?

Isolated gain Correct. Isolated gain systems collect and store solar radiation away from the space to be heated, as described. Isolated gain, or sunspace, passive heating collects the sunlight in an area that can be closed off from the rest of the building. The doors or windows between the sunspace and the building are opened during the day to circulate collected heat, and then closed at night, allowing the temperature in the sunspace to drop.

There are changes to the appliances planned for a new building. In order to accommodate the electrical needs of the new appliances, the voltage for the system must be doubled and the resistance cut in half. How do the changes affect the electrical current?

It is quadrupled Correct. Ohm's Law states that current is directly proportional to voltage and inversely proportional to resistance. State this as the equation I = V/R where I is current, V is voltage, and R is resistance. In this scenario, V increases by a factor of 2 and R decreases by a factor of 1/2. Solving for I, we find that I changes by a factor of 4. The electrical current is quadrupled.

An architect is sizing downspouts and leaders for a multifamily project. Which of the following are determinants of minimum gutter or leader sizing?

Maximum hourly rainfall Correct. The maximum hourly rainfall for a specific location will be used to determine gutter and leader sizes. Roof area Correct. The square footage of a roof that contributes to a specific gutter or downspout will be used to determine sizes. Slope of pipe Correct. The slope of a gutter will be used to determine its required size. Smaller gutter slopes warrant larger channel sizing. Maximum annual rainfall Incorrect. The maximum amount of rainfall is not used to determine sizing of these elements. Rather, the maximum rate of rainfall for a location is used. Slope of roof Incorrect. The slope of the roof is not used to determine the sizing of gutters or leaders, but it would affect placement of these elements.

Should crawl spaces be ventilated or sealed?

New, evidence-based, thinking: Crawl spaces should be sealed: treat them like (small) basements and think of them as part of the building's thermal enclosure. Underlay them with gravel, plastic sheeting, and a concrete slab to keep out groundwater, insulate the walls (but not the overhead plane), and heat/cool them just like the house.

An architect is surveying a 4,500-square-foot cabin in the northwestern United States that is slated for renovation. After bringing in a structural engineer, it is determined that the existing shallow foundations are not capable of bearing the existing loads and the renovation will require deep foundations. What foundation type is best suited for this situation?

Micropiles Correct. Since this is a renovation project and the existing structure is to remain, the smallest and least invasive foundations should be used. Micropiles are installed through the downward force provided by a hydraulic jack. A hydraulic jack is small enough to get close to the existing structure to drive the micropiles in at an appropriate location. H-piles Incorrect. The installation of H-piles requires a pile driver. A pile driver is a large and cumbersome piece of equipment, and it is unlikely that it could get close enough to the existing structure to locate the piles in a place where they could support the existing load.

Piles for a new building's foundation must be used in a sensitive area adjacent to another building. Vibration and disturbance must be kept to a minimum. Which type of pile could be used?

Mini Correct. Minipiles (or micropiles) are small high-strength piles. A small steel casing is drilled into the ground. Steel bars are then inserted into the casing and grouted in place. The smaller size of minipiles makes them suitable for installations where minimizing impact is a main criterion. Helical Correct. Helical piles screw into the soil like a nail screws into wood. This means there is no soil displacement, making them suitable for installations where minimizing impact is a main criterion. Sheet Incorrect. Sheet piles are for excavations, not foundations.

An architect is interested in incorporating a vegetated roof on an existing office building. The system needs to be as light as possible to minimize additional loading on the existing structure. Which of the following vegetated roof systems should the architect propose?

How to calculate Square feet into Square inches?

An architect is specifying a fire suppression system for a small museum building that will house sensitive and expensive artifacts. Which type of sprinkler should the architect specify?

Preaction System A preaction system must go through a two-step process before the sprinklers will realize water. This system is designed to protect spaces with sensitive and expensive materials. The main advantage of pre-action systems is found in the two steps needed for water to release. Since both the pre-action valve and the individual sprinkler head must activate in order for water to be released, it minimizes the possibility of accidental discharge.

Put these in order from most effective insulation to least effective insulation

Perlite-Vermiculite-Most insulation. Perlite and Vermiculite are puffy rocks that have air pockets for thermal resistance, and because they are rocks, they can be exposed to moisture without significantly degrading. Air: More insulation than grout! Air molecules sit farther apart from one another than grout molecules, so air conducts heat more poorly than grout (Which is a good thing when using empty cavities in cold climates) Grout: Pourable and cementitious, grout serves as surprisingly poor insulation, until remember that all dense cementitious serve as poor insulation.

In the site investigation for a townhome development, the geotechnical report describes the building site as four feet of organic fill over twenty-four feet of silty sand on top of bedrock. Which of the following systems would be the best option for the townhomes?

Pile foundation Correct. A pile foundation is a type of deep foundation which is used to transfer heavy loads from the structure to bedrock. In this instance, the bedrock is not terribly far below the surface, and thus pile foundations are a viable option. Combined footings Incorrect. A combined footing is constructed when two or more columns are close enough that their footings would overlap each other. This is used for isolated instances and is not a type of foundation system. Spread footings Incorrect. Spread footings are footings whose base is wider than a typical load-bearing wall foundation. This is the typical option for smaller structures on stable soil.

An architect is working on a new high school building. The initial cost estimate determines that the project is over budget, and it is recommended that value engineering be performed to get the project's budget back on track. Which of the following are reviewed during value engineering exercises?

Product initial costs Correct. Product initial costs are evaluated during value engineering. A higher initial cost can sometimes be justified if cost savings can be accumulated through lower installation costs and longer life expectancy. Energy usage cost Correct. By evaluating the energy usage cost for equipment, it can be determined if a higher initial cost can be justified due to cost savings over the lifespan of the product. Replacement costs Correct. Replacement costs are evaluated during value engineering as a product may have a lower initial cost but higher replacement costs. Depending on the product, it may be determined that it is more economical to provide a product with a higher initial cost and lower replacement cost, or vice versa. Life expectancy Correct. The life expectancy of a product is reviewed during value engineering in order to evaluate its total cost over its entire lifespan. Local availability Incorrect. While selecting products that are available locally does have its benefits, this is not a factor that is typically reviewed during value engineering.

The first modern zoning code was introduced in New York City in 1916. Which of the following exemplify the purpose of zoning?

Protect access to direct sunlight and fresh air Correct. The need for zoning began with the urban growth in the late 19th- early 20th century when it became clear that cities such as New York would soon have streets with limited access to light and air. Ensure incompatible types of building uses do not disturb residents Correct. Zoning is centered on protecting the rights of residents and property owners. This includes disturbances such as putting a school next to a noisy factory. Protect local residents from undesirable types of businesses Correct. Protecting residents from undesirable businesses is a key component of zoning. This concept is in place in order to group compatible businesses and ensure the wrong kinds of businesses don't end up too close to each other. Protect the amount of open space for local residents Correct. The amount of open space directly correlates to the need to maintain access to light and air. Determine the allowable function of a building Incorrect. The allowable function of a building falls under building rather than zoning code. Building codes comprise a set of rules that specify minimal quality and safety requirements. Regulate the number of people or occupant loads of a building or structure Incorrect. Occupancy falls under building rather than zoning code. Building codes comprise a set of rules that specify minimal quality and safety requirements.

Protect and retain existing vegetation Correct. Existing vegetation is already established on the hillside and helps prevent erosion from rainwater. Design development to fit the site and the terrain Correct. Situating the building on an area of the site with flat terrain will limit disturbance of existing soils, which leads to a greater chance of erosion. Revegetate and mulch exposed areas Correct. Added vegetation and mulch help to hold disturbed soil in place and limit erosion from runoff. Strip topsoil from steep hills Incorrect. The loss of topsoil creates major site damage. The onsite loss of this upper layer of soil nearly eliminates the soil's natural ability to provide nutrients, regulate water flow, and combat pests and disease.

An architect is designing a five-home townhouse development where each townhouse will have a full basement. The geotechnical engineer advised the team that groundwater is expected to be found 5 to 6 feet below grade. Which of the following should be included in the design in order to mitigate the effects of groundwater on the foundation?

Provide a foundation drain Correct. Foundation drains allow groundwater to be mitigated and diverted away from the foundation walls.

Provide a foundation drain Correct. Foundation drains allow groundwater to be mitigated and diverted away from the foundation walls. Provide joint sealant at the joint between the foundation slab and walls Incorrect. This should be provided to allow for expansion and contraction between the wall and slab of the foundation, as well as settling. However, this detail is not useful in mitigating the effects of groundwater on a foundation.

What is a variable refrigerant flow (VRF) HVAC system?

Pumps and manifolds move refrigerant to spaces that need heating (high-pressure refrigerant gets hot). And pumps and manifolds move refrigerant from spaces that need cooling (low-pressure refrigerant gets cold). An in-unit fan blows air over the refrigerant coil in each space. Because we can simultaneously heat the perimeter while cooling the core-just by moving refrigerant between the two-this type of system cab often be your lowest energy option. The ductless mini-split system we covered is a type of VRF.

A homeowner in a cold weather climate is remodeling their primary bathroom. Following their architect's suggestion, they will be installing an electric underfloor heating system under the tile flooring for increased thermal comfort in the winter. What is the main method of heat transfer that is utilized by an electric underfloor heating system to heat the air in the room?

Radiation Correct. The electric underfloor coils heat the floor by conduction. However, the air in the room is heated by thermal radiation from the floor. Conduction Incorrect. Conduction is the transfer of heat through a solid or liquid. In the case of an underfloor heating system, the floor itself is heated by conduction, but the room is heated by radiation from the floor.

Radiation Correct. The electric underfloor coils heat the floor by conduction. However, the air in the room is heated by thermal radiation from the floor. Convection Incorrect. Convection is the movement of heat through air or water. An example of this would be a forced air furnace system, where the air is heated by the furnace and physically blown through the space.

What is the difference between Restoration and Rehabilitation and Reconstruction?

Restoration is defined as "The act or process of accurately depicting the form, features, and character of a property as it appeared at a particular period of time by means of the removal of features from other periods in its history and reconstruction of missing features from the restoration period. Rehabilitation emphasizes the retention and repair of historical structures while also allowing latitude for repairs and replacement materials or building additions. Reconstruction Defined as "The act or process of depicting, by means of new construction, the form, features, and detailing of a non-surviving site, landscape, building, structure, or object for the purpose of replicating items appearance at a specific period of time and in its historic location"

A client is interviewing architectural firms regarding their experience and knowledge of evolving sustainable design strategies and technologies. Which strategies or technologies should the firm present to the client during the interview?

Regenerative design Correct. The goal of regenerative design is to produce a net positive environmental impact with respect to energy, water, and materials. This design strategy is new and evolving. Systems include biologically engineered wastewater treatment using living plant species to treat water, generate biomass in aquacultural ponds, promoting green roofs for stormwater management, carbon sequestration, and fauna habitat. Building Integrated Photovoltaics (BIPV) Correct. BIPV is an evolving solar energy technology that architects should be familiar with. The technology embeds photo-voltaic solar cells in the glazing itself, thus maximizing the surface area of buildings for electricity generation. Passive solar design Incorrect. Passive solar design has been around for centuries. The Greeks are considered to be among the first civilizations to design buildings for passive heating potential. Many of the same passive design strategies can be adopted in current design strategies, including building orientation, thermal massing, water harvesting, solar gain, and natural ventil USGBC (U.S. Green Building Council) LEED certification Incorrect. The USGBC LEED certification rating systems for green building design was launched in 2000 and is a popular certification worldwide. In this regard, this topic is not new and has been adopted widely by many U.S. cities into their building requirements. Most architect firms have LEED-accredited professionals on staff.

Rehabilitation facility Correct. A rehabilitation facility is classified as an I-1 Institutional occupancy. Assisted living facility Correct. An assisted living facility is an I-1 Institutional occupancy. Hospitals Correct. A hospital is classified as an I-2 Institutional occupancy. Outpatient clinics Incorrect. An outpatient clinic is classified as a Business (B) occupancy.

Replace portions of the parking lot with pervious pavement Correct. Adding pervious pavement surfaces in the parking lot will reduce stormwater runoff. Install underground stormwater storage below the parking lot Correct. Installation of underground stormwater collection and storage tanks beneath the parking lot is an accepted solution, especially for a site with 73 percent impervious surface areas that are mostly for parking. Install a green roof Correct. A green roof installation is an accepted solution for reducing stormwater runoff. It also adds insulation to the roof, sequesters carbon, and filters air pollution. Plant trees Correct. Planting trees will help collect and store rainfall in addition to providing shade (reducing heat island effect), and improving guest experience. Reduce parking lot surface Incorrect. The building classification code will determine parking lot size, so reduction of spaces may not be an option.

An architect is designing a five-story addition to an existing building, and a separate foundation needs to be designed to support the addition. A subsurface investigation reveals that the soil on the site is predominantly coarse grained. Which type of foundation is most appropriate for the new building?

Shallow foundation with cantilever footings Coarse-grained soil on the site indicates that a deep foundation is not required. A cantilever footing addresses the need to build against an existing building.

The architect selected the beam's size based on resistance to bending moment. What other properties of the beam should be checked before making the final determination on the beam size?

Shear, Deflection & Shear A wood beam is often first designed for file use (bending) and then checked for shear (specially horizontal) and deflection. The end bearing and lateral buckling are also checked. (Beams are note compression members)

An architect is working with a structural engineer on the design of a 1-story masonry retail building. Which of the following describes this building's likely fundamental period?

Short fundamental period Correct. The shorter and stiffer a structure or object, the shorter its fundamental period.

An architect has been commissioned to design an office that utilizes sustainable energy as much as possible. The office will be located in Arizona, so passive cooling will be an essential part of the design. Which of the following options would be the most effective at reducing the solar heat gain?

Shutters on the outside Correct. Reducing solar heat gain is best done by not allowing the sun's rays to enter the building. Exterior shutters stop the sun's rays by shading the glass. Light colored finishes inside Incorrect. Light colored finishes help exterior elements as they reflect the heat, but once solar heat has entered a building the interior finishes don't have a noticeable effect.

An architect is preparing a cost of work estimate at the end of the schematic design phase for a 55,000-square-foot retail project. After studying past projects completed in their office, the architect has decided that the most similar project for which they have cost information is a different office completed three years ago for $250 per square foot. The owner has also provided the following information to be included in the architect's cost of work estimate: Design contingency: 5% Bidding contingency: 7% Construction contingency: 10% Finally, the owner asked the architect to factor in an escalation factor of 2%. Construction is expected to begin in one year. What is the total cost of work estimate? Round to the nearest thousand.

Since the office building that will be used as the basis for cost was completed three years ago and the scenario notes a 2% escalation, the first step is to determine the appropriate cost per square foot to price the project today: $250/sf x 1.02 x 1.02 x 1.02 = $265.30/sf ($265.302)(Note that numbers provided in parentheses show the math that would result from not rounding this first step. Either method is considered correct.)Next, multiply that cost by the square footage of the project: 55,000 sf x $265.30/sf = $14,591,500 ($14,591,610)Next, find the three contingencies noted in the scenario: Design contingency: 5% x $14,591,500 = $729,575 ($729,580.50) Bidding contingency: 7% x $14,591,500 = $1,021,405 ($1,021,412.70) Construction contingency: 10% x $14,591,500 = $1,459,150 ($1,459,161.00) Next, add these three contingencies to the base cost:$729,575 + $1,021,405 + $1,459,150 + $14,591,500 = $17,801,630 ($17,801,764.20)Last, apply the escalation factor to include the fact that construction is expected to begin in one year: $17,801,630 x 1.02 = $18,157,662.60 (18,157,799.48) Round the answer to the nearest thousand, which is $18,158,000.

When conducting a code analysis for a new apartment building, the project lead notes that the project's local jurisdiction has adopted the International Energy Code (IECC), limiting the total power that can be used for lighting a building. Which method may the architect and/or the electrical engineer employe in order to compy with the requirements?

Space by Space Method This method assigns allowable wattage per square foot to spaces based on their user type. When multiplied by the gross area of each programmatic space, a lighting power density can be determined and compared to the code requirement. Note that a GROSS AREA CALCULATIONS approach is incorrect. This measure accounts for exterior walls, including vertical penetrations, and does not consider energy usage. so it is not sufficient by used for determining whether the code has been met.

An architect is looking to implement more environmental strategies in the firm's upcoming projects. Which of the following building and site configurations is best suited to implement passive heating and cooling?

Small single-story residential building on a rural site Correct. Passive heating and cooling strategies are best implemented for small and medium-sized buildings that are on sites which provide flexibility in orientation and configuration. Large single-story office building on rural site Incorrect. Large buildings are not well suited for passive heating and cooling strategies because the typical configurations for these buildings are not compatible with the design elements that are necessary for passive design.

Superplasticizers Correct. Superplasticizers improve the workability of a concrete or mortar mix at a given water-cement ratio. They can also be used to reduce the amount of mixing water needed for a desired workability. Accelerators Incorrect. Accelerators decrease the setting time of a mix, allowing concrete to be placed in winter with reduced risk of frost damage. However, while they speed up the cure time, accelerators do not protect the cured product over the long term against cracking induced by freeze-thaw cycles. Air-entraining agents Incorrect. Air-entraining agents disperse air in the form of small air bubbles throughout concrete, Portland cement paste, or mortar. This has a number of benefits to the cured product when used properly, including improved resistance to frost attack and deterioration. Surfactants Incorrect. Surfactants reduce the surface tension of the water in a concrete or mortar mix. This helps the cement particles and other additives in the mix to emulsify and disperse evenly.

An architect is working on the schematic design of a mixed-use, speculative office building for an urban infill site, where maximizing floor area for rental income is a primary project goal. When working to maximize the economically viable building size for the project, which of the following principles should the architect follow?

The architect should follow an iterative process to maximize the space for the rental area Correct. While working to maximize the economically viable building size, the architect would use an iterative process to maximize the space for the rental area. The architect should make assumptions regarding construction type and evaluate the relative cost-benefit analysis Correct. Before the owner can make a decision, the architect would make assumptions and evaluate the cost-benefit ratio for various construction types. The architect should figure out the maximum allowable height for the site, and then advise the client on which occupancy type would be appropriate Incorrect. The architect would determine the occupancy classification of the building first, and then determine the program area by either program needs or budget. A construction type will be determined after that, usually during schematic design.

An architect is working with their structural engineer on a mid-rise office building where they intend to use a braced framed system. In order to understand which members can be framed out of tensile materials, the architect will analyze the structure using only the lateral forces. Which of the following members will act in compression, tension, or neither? Using the image below, drag the correct designations onto the frame.

Under lateral loading conditions, this system will behave like a large truss to transmit the loads through a series of compression and tension axial members. The horizontal members, where the lateral loads are applied, will experience compression. The diagonal members that go down to the right, will also experience compression, since they are being pushed against. The diagonal members that go up to the right, will experience tension. The load is not directly applied to these members but the force pushing on the horizontal members that they are attached to causes pulling, or tension in these members. The members with no rotation do not experience truss action.

A client has purchased a plot of land and would like to build a prototype on it, requiring very little redesign. One major difference the mechanical team notices is that the original building is in a hot humid climate, and the new location is in a hot arid climate.

The owner has expressed interest in creating artist studios as allowed by zoning. There is concern regarding the adequacy of the existing structural system and its ability to carry loads from heavy equipment. The dead load is assumed to be 50 psf at interior floors, and dead and live loads on the roof are assumed to be 30 psf each. What is the total load that must be carried by a freestanding ground-floor column in the east building?

the answer is 131040 To determine the total load on a ground-floor column, first calculate the tributary area. The tributary area of the freestanding column is found by measuring the distance to each of the nearest columns, and dividing that distance in half. The resultant rectangle (in this example, 26' x 18') is the tributary area of the column. Once the tributary area is determined, the dead and live loads at each floor are multiplied by this value. Add the total calculated at each floor which sits above the column to determine the total load. Tributary Area = 468 sf (26' x 18')Roof load = 60 psf (30psf dead load + 30psf live load - refer to question) 3rd floor load = 110 psf (50psf dead load + 60psf live load - refer to code excerpt) 2nd floor load = 110 psf (50psf dead load + 60psf live load - refer to code excerpt) 468 sf x (60 lbs + 110 lbs + 110 lbs) = 131,040 lbs

An architect is calculating the average expected indoor illumination level in a room from daylighting with an overcast winter sky.The following information is known: The daylight factor in the room is 2% The lowest average outdoor illumination level from an overcast winter sky is 1000 footcandles The size of the room is 16 feet by 18 feet Based on these conditions, what is the average expected indoor illumination level? Reference formula:daylight factor = interior illuminance / exterior illuminance to calculate.

the answer is 20 Daylight factor is defined as the ratio of exterior illuminance to interior illuminance. Use the equation: daylight factor = interior illuminance/exterior illuminance. Rearrange the equation to solve for interior illuminance: interior illuminance = daylight factor x exterior illumination. Solve for interior illuminance.0.02 x 1000 = 20 footcandles

An architect is designing a new Prairie-style house with three-foot roof eaves on a 50-foot-wide lot. The zoning ordinance requires five-foot side yard setbacks and allows the roof eaves to project no more than two feet into the setbacks. What would be the maximum allowable width of the house per the zoning ordinance?

If the house has three-foot wide eaves and the zoning ordinance allows the eaves to project up to two feet into the side yard setback, then the exterior walls of the house would need to be located one foot to the inside of each side yard setback.50' wide lot - 10' (two five-foot side yard setbacks) - 2' (two additional one-foot setbacks due to eaves) = 38' maximum house width.

Incorrect - the answer is 595 Because the two columns are identical (e.g., there are two HSS12x12 columns), each column resists ½ of the total seismic force; so we divide 70 kips / 2 = 35 kips (this force will act horizontally upon the hinged connection at the base of each column). The height of the columns is 17 ft. Thus, the moment value at point B will be:M(B) = 35 kips x 17 ft = 595 kip-ft.

An architect is designing a sign that must be legible to pedestrians from a distance of 60 feet away. The architect is following a guide that states that the letters are to be 3 inches high for the first 21 feet of viewing distance and an additional 1/8" higher for every foot of viewing distance beyond that. What is the minimum height for the letters on the sign? Round to the nearest inch.

Incorrect - the answer is 8 Find how many inches need to be added to the base of 3 inches in order to be readable at a distance of 60 feet.60 feet - 21 feet = 39 feet. 39 x 0.125" = 4.875". Adding 4.875" to 3" = 7.875". Round up to 8".

An architect is working on a new ski resort clubhouse. In an effort to keep the mechanical equipment on the roof hidden, the architect has decided to enclose the equipment with a large screen wall. The screen wall will be attached to the main roof structure at the corners with posts. Which of the following changes to building loads will have the greatest impact on the structure?

Increased snow load Correct. Snow drift occurs when vertical members are present on roofs; the snow drifts towards those members, and piles up against them. This also can occur at parapet walls on flat roof construction. The increased snow load due to drifting will increase the load on the roof framing. This increase can impact a large portion of the roof system depending on the overall size and geometry of the equipment screen. Increased roof dead load Incorrect. The increased roof dead load will be minimal as the load from the screen wall will be transferred to the main structure through each of the four posts, meaning that each post will apply a point load to the structure equal to 1/4 of the total screen wall load.

Infill development Correct. An infill development would be most appropriate for this project, as this type of development takes advantage of vacant or undeveloped properties while utilizing the existing infrastructure of the neighborhood. Transit-oriented development Incorrect. While a transit-oriented development takes advantage of existing infrastructure, this type of development is typically much larger than this application. Infill development would be more appropriate.

Maintain on-site daylight access Correct. Arrangement of adjacent buildings, site features, and building orientation provides daylighting opportunities. Utilize reflection and incorporate diffused light to promote daylighting deeper into the building core Correct. Reflected and diffused light redirect daylight effectively, while reducing glare into a building's interior. Rooms must be well- proportioned and sized correctly for this strategy to work. Manage glare by specifying tinted glass Correct. Mitigating glare ensures occupants will refrain from using blinds to completely block daylight. Modify the landscape design to use planting to modulate and filter sunlight based on each location Correct. In a temperate climate in the northern hemisphere, the architect could use deciduous trees or vines to shade the south facade in winter, and allow light and radiation in the winter. In a cold climate in the northern hemisphere, the architect might avoid plantings along the south facade. In an arid climate in the northern hemisphere, the architect could specify drought-tolerant trees around the east, west and south facades to provide shade.

A developer is evaluating alternative sites for a luxury residential development. Despite higher development costs, they feel that a hillside site will warrant greater market values because of the views and unique character of the terrain. What is typically the most cost-effective means to develop the site while retaining its character?

Minimize disturbed areas Correct. Minimizing disturbed areas on the selected site is typically more cost-effective and will have less of an impact on natural drainage patterns and habitats. It also allows the finished grading to more closely mimic the original terrain and retain the character of the site. Straighten the slopes Incorrect. Straightening the existing slopes on the selected site can negatively impact the natural appearance of the terrain and affect drainage patterns.

Modular block vegetated roofing system Correct. The modular block system typically only require 3-4 inches of engineered soil to sustain growth. This typically adds an average of 12-18 pounds per square foot of additional load to the structure. Extensive vegetated roofing system Incorrect. An extensive system typically requires 4-6 inches of engineered soil and can add roughly 15-50 pounds per square foot to the roof structure. A modular block system is more appropriate. Intensive vegetated roofing system Incorrect. Intensive vegetated roofing systems require a minimum of 12 inches of soil and can add anywhere between 80 and 150 pounds per square foot to the existing structure.

The architect for a new forestry station in a national park has ordered a geotechnical survey with six soil borings to confirm the soil conditions of the project site. They will use the recommendations from the survey to determine the type of foundation needed to support the building. What types of soil information will the geotechnical survey provide? Check the four that apply.

Moisture content Correct. Soil borings will indicate the amount of moisture that is being held by the soil. Cohesion Correct. Soil borings will indicate the cohesion of the soil, which is the strength of the soil when unconfined and air-dried. Permeability Correct. Soil borings will test the soil's permeability, which is the amount of liquid or gas that can pass through its pore spaces. Shearing strength Correct. Soil borings will indicate the shearing strength of the soil, which is the ability of the soil to resist displacement from adjacent soil when an external force is applied to it. Frost level Incorrect. The frost level is not part of a soil report, but is a predetermined depth of frozen subsoil for a particular region of the country.

Refer to the plans of buildings A and B in the graphic. A building's planned columns are redistributed from the configuration in Figure A to now be on the periphery, as is shown in Figure B. What has increased as a result of this change?

Moment of inertia Correct. Moving mass farther from the centroid of either a beam or, in the case of this question, the whole building, increases the moment of inertia. Moment of inertia is defined as "the sum of the products of all the elementary areas times the square of their distances from the neutral axis." Moving the columns to the exterior of the building makes the structure stiffer as a whole. This is the same concept that gives the wide flange beam the "I-beam" shape.

The architect and owner of a proposed new neighborhood cultural center are seeking input from stakeholders with an interest in the project. In which of the following groups would the stakeholders represent their own individual interests?

Neighborhood business owners Correct. Individual neighborhood business owners can speak for themselves and represent the "typical" views of other business owners in their neighborhood. Neighborhood associations Incorrect. Neighborhood associations would fit into the "interest group" category of stakeholders. Individuals in these associations represent their organization's interests rather than their own individual interests.

An architect is reviewing product information for fire suppression systems. The product info states that ordinary sprinkler heads operate between 135 and 170 F, whereas the newer quick- response heads trigger at a lower temperature. Which of the following building types should the architect specify quick-response sprinklers for? Check the four that apply.

Offices Multi-family residential Hotels Assisted living facilities Correct. All light hazard occupancies are required to have quick-response (or fast-response) sprinklers. These include hotels, motels, offices, residential, healthcare, and other buildings where faster sprinkler operation could enhance life safety. The biggest difference between quick-response and standard-response sprinkler heads is their activation temperatures. As the name suggests, quick-response sprinkler heads activate sooner. Factory Incorrect. Standard-response sprinklers are used in factories and warehouses, where occupancy is low.

An architect is working on a renovation to an existing office building. The owner has asked to incorporate sustainable practices on the property, but would like to minimize the impact to the existing building as much as possible. Which of the following solutions should the architect suggest?

Photovoltaic array Correct. Adding a photovoltaic (PV) solar array would be the best suggestion given the desire to minimize the impact on the existing building. PV arrays can be ground-mounted, which eliminates the need to attach to the roof, and the connections can be made within the electrical room, meaning that the only modifications required are the new inverter and battery bank. Geothermal heat Incorrect. A geothermal heating system would involve substantial reconfiguration of the existing heating and cooling system, as well as additional disruption to the facility during the drilling of the wells required for the system to operate.

An architect is preparing the design and detailing for a below-grade basement for a new custom home. The home sits on a site with a variable water table where moisture intrusion and hydrostatic pressure are of concern. Which of the following are the most effective methods for creating a waterproof basement? Check the three that apply.

Placing a moisture barrier before pouring the foundation Correct. Placing a moisture barrier below the foundation will aid in reducing water and moisture penetration up into the slab. Placing a course of gravel beneath the foundation pour Correct. The gravel course will provide a porous surface for water to drain into the ground below as opposed to soil, which may gather water and cause capillary or increased hydrostatic pressure on the foundation slab. Placing perforated drain tile around the foundation, above the concrete footing Correct. Placing the pipe around the foundation will allow water to flow away from the foundation to keep the basement dry. Applying damp proofing around the exterior foundation wall Incorrect. Dampproofing is a layer applied during the foundation process, intended to keep soil moisture out of the building. It is not an effective long-term solution, as it is unable to seal large cracks in the concrete and may be subjected to damage during backfill operations.

The owner and architecture team are developing a property into a country estate and golf course. They are looking at wetlands as a sustainable strategy for managing stormwater. The area available for wetlands development is approximately six acres, shoe-horned between the country estate and the golf course. As an active course, the owner would like to minimize the attraction of native species and wildlife. Overall, the project is aiming for a moderate pollutant removal in coordination with other treatment measures onsite. Which one of the following wetland designs would the civil engineer most likely recommend?

Pocket wetland Correct. The pocket wetland is suitable for up to 10 acres and due to the smaller size, is not an attractant for wildlife. In addition, it has only moderate pollutant removal, and is compatible with the stated goals of the project. Also, the system is more malleable to fit into the ancillary space between the estate and the golf course. Shallow marsh Incorrect. This system would require approx 25 or more acres of available land to be effective, as shallow marsh consumes much land. In addition, the large spread would attract wildlife. This system is more applicable to high pollutant removal, which is not necessary for the stated goals of this wetland project. Pond wetland Incorrect. This system would require approx 25 or more acres of available land to be effective. This system also tends to attract waterfowl and cleans a very high level of pollutants, which is not compatible with the programming goals of this project. Detention pond Incorrect. Requires a minimum of 10 acres to be effective. While the removal of pollutants would be in line with the goals, it also tends to attract wildlife due to the size of the pond, and is not compatible with programming goals of this project.

A design-build firm is researching Forest Stewardship Council (FSC) certification. Which of the following is accurate pertaining to wood certified by the FSC?

The wood was harvested without violating peoples' rights Correct. The FSC (Forest Stewardship Council) is a global nonprofit dedicated to responsible forest management. Indigenous Peoples' Rights is Principle 3 of FSC certification. The wood is locally sourced Incorrect. The FSC certifies that wood has come from responsibly managed forests. There is no requirement that a wood be locally sourced to be FSC-certified.

Fire protection is an important part of the design of a new building. Which of the following choices accurately lists the priorities for designing for fire protection in buildings?

Protecting the building's occupants > Protecting the building itself > Protecting the building's contents Correct. Protecting the people inside the building is the top priority, followed by protecting the building, and then the things inside the building. Ensuring access for fire and rescue personnel > Providing adequate water supply for fire-fighting > Limiting quantity of combustible material Incorrect. These are not the guiding priorities (which are protection of the occupants, the building, and the contents), but they are important details that will affect the protection of the priorities. Therefore, how rescue personnel access the site and combat the fire event is addressed throughout various sections of the IBC and municipal code.

The architects for a proposed recreation center building in an urban neighborhood are discussing the best options for receiving community input on the project. Which of the following options are ways to engage local community stakeholders in the design process? Check the three that apply.

Questionnaires Correct. Well-formatted questionnaires for local community members can solicit input on the needs and concerns of neighborhood stakeholders. Interactive workshops Correct. Interactive workshops with local community members allow for a give-and-take of ideas that are important to the local stakeholders and helpful to the architect. They can alleviate stakeholder concerns about the project and allow for understanding and support from the community. Design charrettes Correct. Engaging community members in design charrettes can be an effective and satisfying experience for local stakeholders while providing useful design input for the architect. Planning commission meetings Incorrect. Planning commission meetings are geared more toward comments and approvals from the planning board, rather than community members. Although community members often have an opportunity to make comments, it is not a proper forum for engaged community input.

A three-story building housing a mineral spa was built in the 1920s as a tourist health destination. The building fell into disrepair in the 1960s and was unused for several decades. The building was listed on the National Register of Historic Places in 1979. In 2002, the first floor of the building was flooded when the nearby creek overfilled. The flooding left the building derelict and close to being condemned. A new owner has purchased the building and would like to convert it back to the mineral spa. Which treatment of historic structures should the architect recommend?

The flooding left the building derelict and close to being condemned. A new owner has purchased the building and would like to convert it back to a mineral spa. Which treatment of historic structures should the architect recommend?

Rehabilitation Correct. Rehabilitation emphasizes the retention and repair of historical structures while also allowing latitude for repairs and replacement materials or building additions. By rehabilitating the space, repairs and appropriate replacements can be made while holding true to the original intent of the structure. Restoration Incorrect. Restoration is defined as "the act or process of accurately depicting the form, features, and character of a property as it appeared at a particular period of time by means of the removal of features from other periods in its history and reconstruction of missing features from the restoration period." There is no indication of the need to remove features from other periods of time. The building only needs to be rehabilitated.

Replacement costs Replacement costs are evaluated during value engineering as a product may have a lower initial cost but higher replacement costs. Depending on the product, it may be determined that it is more economical to provide a product with a higher initial cost and lower replacement cost, or vice versa. Life expectancy Energy usage cost By evaluating the energy usage cost for equipment, it can be determined if a higher initial cost can be justified due to cost savings over the lifespan of the product. Product initial costs Product initial costs are evaluated during value engineering. A higher initial cost can sometimes be justified if cost savings can be accumulated through lower installation costs and longer life expectancy. Note: While selecting products that are available locally does have its benefits, this is not a factor that is typically reviewed during value engineering.

An architect has been hired to perform a programming analysis for a new preschool. The architect's firm specializes in educational facility design but has not recently completed a preschool. What is the first step the architect should take in the programming process?

Research the project type Correct. This is the first step in a programming exercise. It is important to study precedents before proceeding further with any analysis, especially since the firm has not completed a preschool design in the recent past. Identify programming strategies Incorrect. This step can only be successfully done after the architect has researched the project type, established goals, gathered data, and analyzed the data.

A building design is to include photovoltaic (PV) panels as a component of the electrical system. Which of the following is an appropriate material for photovoltaic cells?

Silicon Correct. Photovoltaic cells require a semiconductor to create the flow of electricity. Silicon is the only semiconductor of the materials listed here, though alternatives such as amorphous materials are also available.

An architect is detailing a wall assembly for a multi-family residential building. Which of the following wall types will provide the greatest thermal and acoustic insulation?

Staggered stud with insulation Correct. A staggered stud wall with insulation would provide the greatest thermal and acoustic insulation, because staggering the studs prevents thermal bridges and reduces the transmission of acoustic vibrations. 8" CMU, painted Incorrect. An 8-inch CMU wall would provide some level of acoustic insulation, but would not provide adequate thermal insulation. Double-wythe CMU wall Incorrect. A double-wythe CMU wall would provide some thermal and acoustic insulation, but not as much as the staggered stud wall.

The owner of a private art collection is looking at two potential building sites for his next gallery. The owner's main desire is to display the artwork in a naturally lit space. Which of the following site analysis diagrams would help the architect choose a site that fits the owner's main desire? Check the three that apply.

Sun path diagram Correct. This diagram would help in choosing the site that can best provide daylight at specific hours of operation and help in determining any necessary shading. Vegetation diagram Correct. This diagram can show where existing mature planting is located that may hinder daylight penetration into the space and potential site situation. Building height diagram Correct. A building height diagram can inform the owner of the surrounding building heights and potential for casting unwanted shadows on the site, limiting the potential for daylight.

The architect has selected heavy timber framing for a new office building in a dense downtown area. In order to get the height of the building and of the spaces, the architect needs to preliminarily size the structural members. What should be the minimum dimension between the bottom of the beam and bottom of the girder?

The girder should be at least 2" deeper than the beam it supports. This allows for a char layer to occur on the girder while not compromising the integrity of its support of the beams.

An architect is considering the benefits and limitations of entry systems for a new mixed-use building located in downtown Portland, OR. The street level of the building will contain various retail stores, two restaurants, and access to a business lobby which houses elevators for the offices on the upper floors of the building. The architect is reviewing the specifications for the installation of revolving doors at the building's main entrances. Which is true regarding revolving doors?

The practical capacity of each system is 25-35 people per minute Correct. Revolving doors can typically accommodate fewer people than sliding or swinging door systems. Depending on the size and speed of the revolving doors, approximately 25-35 people per minute can obtain entrance and/or egress. The doors can be accommodated on separate slab foundations Incorrect. Revolving doors must be mounted entirely on one slab foundation. If the doors span across multiple slabs and one slab is subject to settling, the doors may be off center and unable to revolve properly. Revolving doors contribute in full toward egress capacity Incorrect. Revolving doors are not considered to be egress options on life safety plans, and are therefore not able to contribute in full to egress capacity for a building. Some jurisdictions allow for revolving doors to count as 50% of legal exiting requirements, while others do not count them at all.

An architect is putting the finishing touches on the site plan for a new sports complex when an email comes in from the electrical engineer. It states that the kVA equipment has to be moved to the south end of the site. Which piece of electrical equipment carries a kVA rating?

Transformer Correct. Transformers and generators carry kVA ratings, which is a measure of power. kVA stands for kilovolt-amperes. Kilovolt-amperes are calculated by multiplying the volts and the amperes.

A developer and their architect are planning to build a mixed-use building on a large suburban downtown site that is located two blocks from a commuter rail station. The building will contain high-density commercial and residential uses, with a pedestrian orientation and reduced parking requirements. Based on this information, what type of project is being proposed by the developer and the architect?

Transit-oriented development Correct. A transit-oriented development is a development typically located within a 10-minute walk from a transit station. To take advantage of the proximity to transit, the development is usually characterized by high density, mixed uses, pedestrian accessibility, and reduced parking requirements. Neighborhood center development Incorrect. Neighborhood centers provide more localized availability of goods and services for area residents within a neighborhood. They are developed as the focal point of the neighborhood and are usually located near the neighborhood's core. Besides residential and retail uses, a neighborhood center might contain professional offices, schools, restaurants, religious facilities, and public spaces.

A new concrete parking structure with a capacity for 3,500 cars is being designed in the city center. It has been established that the structure will be built using rapid slip form construction. Which type of cement should the architect specify?

Type III Correct. Type III achieves strength values quicker than Type I, allowing the forms to be stripped sooner. Type I Incorrect. Type I is normal cement. This type is inappropriate for multi-level pours because of the time it takes to develop strength. Construction can proceed at a much faster pace for multi-level projects with other cement types. Type II Incorrect. Type II is moderate-sulfate-resistant cement, to be used when concrete is cast against soil that has moderate sulfate levels. Type IV Incorrect. Type IV is a low-heat-of-hydration cement, for use where the rate and amount of heat generated must be minimized. It develops strength at a slower rate than other types and is not suitable for the type of construction described in the question.

A family is consulting with an architect about designing a new custom residence. In addition to their current needs, they are also planning to have a cousin who uses a wheelchair come live with them sometime in the next five to ten years. The family needs the architect to design a home that will meet all of their needs now and in the future, without having to make adjustments when their cousin moves in. What principle of design should the architect follow for this project?

Universal Correct. Universal design is the creation of an environment that can be used to the greatest extent possible by all people regardless of their age, sex, size, or ability. It is a fundamental principle of good design that goes beyond just meeting the needs of a single individual. It makes accessibility an intrinsic part of the design of the home. Note: Adaptable Incorrect. Adaptable design looks at the ease of altering a room or space to meet the needs of individuals in the future. It does not address the needs of all of the users of the building like universal design does.

An architect is working on a new high-rise building and the client requests that sustainable materials and practices be used as much as possible. Which of the following are strategies the architect could employ to meet the client's goal? Check the four that apply.

Utilize prefabricated building elements Correct. By utilizing prefabricated building elements, there is less field-cutting of materials and job site waste can be decreased. Minimize field finishing of materials Correct. By finishing materials in the factory, the contaminants in the air on the job site can be reduced. These include volatile organic compounds (VOCs), dust from sanding, etc. Utilize smart technology Correct. Utilizing smart technology within the building is a great way to allow for the property to be more efficient in its operation. This technology includes occupancy sensors, smart thermostats, building automation systems, etc. Select products with high recycled content Correct. By selecting products with high recycled content, fewer raw materials need to be harvested. Specify high-VOC paint Incorrect. Specifying low-VOC (volatile organic compound) paint would help the client achieve their goal of a sustainable project.

Value engineering Correct. Value engineering by the owner or contractor to reduce costs during construction can have an impact on overall building and systems performance and certification. The architect should notify the owner and contractor of performance or certification issues that could be a result of proposed changes to the drawings and specifications. Building systems operation and maintenance Correct. When energy usage does not meet specific goals, it is often caused by the owner not operating the building systems as they were designed to be run. Contractor documentation Correct. The contractor must accurately compile the required documentation during construction that will be submitted for LEED certification. If the contractor fails to provide this information, the building may not be certified. Certification approval Correct. LEED certification is not guaranteed. Various elements in the final construction and submitted documentation could affect whether certification will be awarded, or what the level of certification will be. Shop drawing approvals Incorrect. Shop drawing approvals by the architect should not affect the ability to meet sustainability goals, if the submittals meet the project specifications. If a submittal is made that does not meet specification or performance criteria, the architect should make note of the fact and return the shop drawing unapproved.

Wall insulation requirements Correct. The IECC specifies the wall insulation requirements. Lighting controls Correct. The IECC specifies lighting control requirements to maximize energy efficiency. Electrical power consumption Correct. The IECC specifies the maximum electrical power consumption for different features such as electric water heaters and lighting. Total building performance requirements Correct. The IECC denotes the requirements for total building performance. Glazing thickness Incorrect. While the IECC specifies thermal performance criteria for glazing, the overall construction of the glazing assembly is controlled by the IBC. Ventilation requirements Incorrect. Ventilation requirements are defined in the International Mechanical Code. However, the IECC does specify the efficiency requirements for various pieces of mechanical equipment.

An architect is evaluating materials for the structural system of a new medical office building. Since the project is only going to be one story, the architect is considering both light gauge metal framing and wood framing for the project. What are some of the benefits to using light gauge metal framing instead of wood framing? Check the four that apply.

Water resistance Correct. Metal studs typically have a galvanized coating applied to them in the factory, giving the studs a greater water resistance than non-treated wood studs. Larger load capacity Correct. Steel studs have a higher load capacity compared to traditional wood studs. In addition, studs of the same depth are available in a range of steel thicknesses, which allows for heavier loads within a wall to be carried while still maintaining a consistent depth. Noncombustible Correct. While wood can be treated with a fire-retardant coating, metal studs are inherently noncombustible without additional treatments. Increased construction efficiency Correct. Metal studs can be delivered with pre-punched web holes, allowing for faster completion of utility rough-ins.

Wind rose Correct. A wind rose depicts wind directions over a period of time and can be used to determine the prevailing wind directions in that location. Wind sock Incorrect. A wind sock is used to measure wind speed and direction at a given point in time. A wind rose would be more appropriate because it depicts wind speeds and directions over an extended period of time.
