Practice test 3

The LEED Integrative Process has three phases crucial to the project's ongoing success. What are they? (CHOOSE 3) Occupancy, Operations, and Performance Feedback Charrette Design and Construction (Implementation) Value Engineering Discovery

1, 3, 5. Discovery: This is the most important phase of the integrative process; it can be thought of as an extensive expansion of what is conventionally called "Pre-Design." It is unlikely that a project's environmental goals will be achieved cost-effectively if this phase is not rigorously engaged as a discreet phase of the design process. Discovery work needs to be accomplished before "putting pencil to paper"— in other words, before schematic design begins. Implementation: This phase begins with what is typically called "Schematic Design." It resembles conventional practice in its structure, but integrates all of the work and collective understanding of system interactions reached during the Discovery Phase. Feedback: The third stage focuses on implementing performance measurement and creating performance feedback mechanisms. Such feedback is critical to building operations. The degree to which established performance targets have been met can be assessed and then corrective actions can be taken. The LEED Charrette is an example of a concept used in the Discovery phase. Value Engineering is the cutting of costs, often during construction phases, which affects the actual value of a project.

55-2010. ASHRAE Standard 55-2010 establishes the six factors that affect thermal comfort, air temperature, radiant temperature, air velocity, humidity, clothing insulation, and metabolic heat.The others:• ASHRAE Standard 62.1-2010: ventilation (minimum rates)• ASHRAE Standard 52.2-2007: ventilation (air filters)• ASHRAE Standard 90.1-2010: energy efficiency

Prior to submitting a LEED Interpretation, a project team must first do the following: Contact USGBC customer service Contact the GBCI and explain the issue Ensure the project is LEED Platinum Have the inquiry go through the project CIR process Have a committee review the request

All formal inquiries first undergo the project CIR process. Project teams that want the formal inquiry to be considered for a LEED Interpretation must opt in and pay for the LEED Interpretation at the time that it submits the inquiry.

LEED for Neighborhood Development has two rating systems within it. It also has some unique credit categories. Which one of the following is not one of them? Smart Location and Linkage Innovation Awareness and Education Neighborhood Pattern and Design Green Infrastructure and Buildings

Awareness and education - covered under innovation

How many LEED rating systems are there? 21 5 19 10

BD+C = 10ID+C = 3O+M = 6ND = 2 Total= 21

Which is a renewable resource? Natural Gas Fossil Fuels Clean Coal Biomass

Biomass

Credit interactions and synergies are key to reducing the cost of LEED certification. Once those interactions and synergies are identified, the project team can develop strategies to better tackle which of the following? (CHOOSE 2) Construction activity pollution prevention Designing for flexibility Open space Site assessment Water and energy submetering Habitat conservation and restoration

Both 'Habitat conservation and restoration' and 'Construction activity pollution prevention' involve preserving and protecting greenfields during the construction process. Since they are broad areas, many aspects of the project will affect them. Thus, a project team can reduce costs if it identifies interactions and makes use of the synergies.

A project team is having difficulty at different stages of a project's LEED process. When would a project team choose to submit a Credit Interpretation Request (CIR)? (CHOOSE 2) When a conflict in a credit or prerequisite requires resolution When the LEED consultant is having difficulty registering a project and needs assistance When the reference guide does not address a specific issue When the owner cannot find a LEED consultant in the area When a project is denied a credit and wants to appeal

CIRs should be used when there are conflicts in a credit or prerequisite and/or you can't find the answer in the reference guide.

The material specification team requires information on the environmental impact of a manufacturer's extraction operations and the product's supply chain. How can this be found? By reviewing the manufacturer's corporate sustainability report By reviewing the product's health product declaration By conducting a life-cycle assessment of the product By ensuring that the product is LEED approved By ensuring that the manufacturer's company is a USGBC member

CSR. A Corporate Sustainability Report (CSR) is a third party, verified report that includes information on how the manufacturer extracts or sources materials. A Life-Cycle Assessment is specific to a product, not the manufacturer's operations and supply chain in general. Same for a health product declaration.

RioCan just purchased the Yonge-Sheppard Center and will retrofit the envelope, HVAC, domestic hot water, and electric systems. Tenants will still control their own spaces, which will not be upgraded. Which LEED rating system should be used? LEED BD+C: Schools LEED O+M: Existing Buildings LEED BD+C: New Construction LEED BD+C: Core and Shell LEED ID+C: Commercial Interiors

Core and Shell

Energy Use Intensity (EUI) is an important factor in determining energy usage. What does EUI refer to? The total daily energy use Energy consumption divided by the site area The ratio of maximum daily energy use divided by the total annual energy use The amount of energy consumed per unit of floor space

Energy consumed per unit of floor space. When a building is benchmarked, as in ENERGY STAR Portfolio Manager, one of the key metrics is Energy Use Intensity, or EUI. Essentially, the EUI expresses a building's energy use as a function of its size or other characteristics. For most property types in ENERGY STAR Portfolio Manager®, the EUI is expressed as energy per square foot per year. It's calculated by dividing the total energy consumed by the building in one year (measured in kBtu or GJ) by the total gross floor area of the building. The user can enter the energy use information from their energy bills and ENERGY STAR Portfolio Manager® automatically does the conversion to thousand British thermal units (kBtus). Generally, a low EUI signifies good energy performance.

Select one low-cost structural incentive that a municipality can give to a developer to encourage green building? Permit fee waivers Green building grants Tax credits Allowing increases in the floor-area ratio

FAR. Local zoning codes cover floor-area ratios, and thus could be set by municipalities. The rest are financial, not structural, incentives.For more information about different incentives please read here: http://leadinggreen.ca/wp-content/uploads/2014/08/Green-Building-Incentive-Strategies.pdf. Other structural incentives include:• Expedited review/permitting process• Density and height bonuses Financial incentives include:• Tax credits• Fee reductions/waivers• Grants• Revolving loan funds (low-interest loans) Non-financial incentives include:• Technical assistance• Marketing assistance

When is a project allowed to show its LEED certification plaque? After the substantial project completion phase When the project is approved by a LEED AP Following the acceptance of a final certification review After successful registration and prerequisite compliance

Final certification review

There are many ways to fight the damages caused by refrigerants, but this is not one of them: Select refrigerants that have long atmospheric lives Specify refrigerants with low ozone depletion potential Ensure ventilation rates meet ASHRAE 62.1 Design the building to use natural refrigerants

First answer. A high ODP (Ozone Depletion Potential) is directly correlated with a long atmospheric life, and thus this choice would hinder environmental performance.

A team is trying to decide between two different office desks. One is made from overseas-imported bamboo and the other is made from local maple. How can the environmental attributes of the products be compared? Through a life-cycle assessment By a review of the manufacturer's corporate social responsibility policy Through material-quality testing Using the products' material safety data sheets (MSDS)

How can you, as a LEED consultant, make a suggestion that would lower operating costs and increase energy efficiency in a new school? Ensure that triple-paned glass windows instead of double-paned glass windows are used Install all LED lighting Place a PV array on the schools roof Maximize the ventilation of outdoor air

LED lighting

LeadingGreen has almost completed all LEED documentation for its new office tower. The USGBC believes that it has found an error in the LEED rating system. How should USGBC address this error? LEED Addenda LEED TAG will review the issue and save it for the release of the LEED v5 rating system LEED Interpretation Issue out a LEED Interpretation

LEED Addenda. LEED Interpretations and CIRs are technical answers to clarifications.The USGBC publishes clarifications (also called addenda) to address errors in the LEED rating systems and reference guides.LEED TAGs (Technical Advisory Groups) provide technical advice to LEED committees and working groups to improve credits/prerequisites and support tool development.

What type of buildings do 'LEED BD+C: New Construction', 'LEED BD+C: Core and Shell', 'LEED BD+C: Schools', and 'LEED O+M: Existing Buildings' evaluate? (Choose 3) Community development Interior spaces High-rise residential buildings Institutional buildings Commercial buildings

Last 3

A developer cannot determine how many buildings he wants to locate on a large site. What LEED rating system extends past the project and into the local and regional communities? LEED BD+C: Schools LEED ND LEED BD+C: Homes LEED BD+C: Retail

ND goes beyond the project itself. The system addresses the land use planning of a neighborhood by addressing its components: building design, infrastructure, street design, and open spaces.

What is one of the primary goals of the commissioning process? The project complies with local building codes The project complies with the Owner's Project Requirements (OPR) The project will earn enough points for certification The project complies with the Commissioning Authority Basis of Design (BOD)

OPR. Commissioning is a process for achieving, verifying, and documenting that the performance of facilities, systems, and assemblies meets defined objectives and criteria as established by two fundamental documents, one prepared by the Owner—Owner's Project Requirements (OPR)—and the second prepared by the project team—Basis of Design (BOD). The Fundamental Commissioning and Verification prerequisite requires the project team to engage a commissioning authority by the end of the design development phase, review the OPR and BOD, and prepare a facilities operations and maintenance plan. This prerequisite primarily addresses active systems, which includes the project's mechanical, plumbing, electrical, and renewable energy systems. The Enhanced Commissioning credit offers several options, including commissioning of the building envelope. Although enhanced commissioning can add sufficient cost to the project and extends the certification time by 10 months, it is important in that it maintains the integrity of the envelope (roofing, siding, windows and doors, and waterproofing (e.g., caulking, flashing, etc.)). Ongoing commissioning (aka recommissioning): for building operations to ensure that a building continues to meet its fundamental operational requirements. Retrocommissioning is the same process applied to existing buildings and it is intended to keep a building on track for meeting or exceeding the original operational goals.

Looking at the LEED rating system, it is very complex with many different paths to achieve each credit. Some even have an LPE option. What is an LPE? A LEED Accredited Professional A Letter of Potential Excellence A Licensed Professional Exemption A LEED Pilot credit

Professional exemption. A Licensed Professional Exemption (LPE) is an optional credit documentation path in which professionals can submit license information and a declaration of compliance in lieu of a number of otherwise required submittals. Credit forms automatically recognize and link Licensed Professional (LP) information from user account data when that user accesses the credit form. LP Information must be identified on the "My Account Page" of the user's account, or during user registration. This information is visible on a project's "Team Administration" page, but can only be added or changed from the "My Account" page. For LPE paths with multiple sign-offs, more than one team member may be assigned to the credit or prerequisite for signatures (see "Assign Credits"). Note: It is not required that the LP be a LEED AP. LPE streamlined paths are available to:• Professional Engineers (PE)• Registered Architects (RA)• Registered Landscape Architects (RLA)• Registered Interior Designers (RID)

The building code in Pittsburgh allows for smoking in restaurants. As a result, a consultant for a new bar suggests having a dedicated smoking room, which would mean: The project can automatically receive LEED points The project would have to ensure proper compartmentalization in the isolated room to become LEED certified The project is exempt due to location and service The project can not be certified

Project cannot be certified

A project uses an on-site wastewater treatment plan and uses the treated wastewater to replenish the aquifer below, helping to: Reduce the amount of wastewater from the building Reduce irrigation requirement of on-site rain gardens Reduce the demand for on-site potable water Reduce the demand for wastewater treatment infrastructure

Reduce the demand for wastewater treatment infrastructure. This on-site wastewater treatment plan reduces the demand for wastewater treatment infrastructure elsewhere, and reduces the energy required to treat the water due to the short distance it travels to the treatment plant. As a result, there is a reduction in GHG and other pollutants that are created by water transportation and treatment facilities, which improves the quality of life for humans and lessens environmental burdens. Irrigation requirements are not affected, and the amount of wastewater leaving the building is not necessarily reduced.

A delivery truck had a leak in its roof, and as a result, some building materials got wet. What should the project team do with these materials when they get to the site? Replace the materials Install them immediately Wait for them to dry before installing Recycle the materials

Replace the materials. The Construction Indoor Air Quality Management credit (EQc3) requires a project to develop and implement an IAQ management plan during construction and before occupancy. This credit promotes best practices to ensure high indoor air quality during construction, as outline in the Sheet Metal and Air Conditioning National Contractors Association (SMACNA) IAQ Guidelines. A general contractor is responsible for keeping building materials dry so that no mold is introduced into the building, as mould would negatively affect the indoor air quality.

There are 6 main LEED credit categories that make up 100 points. Some of the points are awarded for strategies that minimize the impact on ecosystems and water resources under what credit category? Energy and Atmosphere Location and Transportation Water Efficiency Sustainable Sites Materials and Resources

SS - Sustainable Sites credits encourage strategies that minimize the impact on ecosystems and water resources. Water Efficiency credits promote smarter use of water, inside and out, to reduce potable water consumption. Location and Transportation credits reward projects in relatively dense areas, near diverse uses, with access to a variety of transportation options, or on sites with development constraints.

Donald Sterling only cares about the economic return of a building, so why would he certify it as LEED? Certified buildings cost less than conventional buildings Certified green properties receive 0%-interest loans Certified green office buildings rent for 2% more than comparable buildings Certified buildings have guaranteed incentives in all jurisdictions In hopes of getting the LA Clippers back

Studies show that on average, a green building can charge higher building rents (2%-20%, on average) and have fewer empty tenant spaces than non-green buildings.

If 16 people work for 4 hours a day, 20 people work for 6 hours a day and 10 people work for 8 hours a day, how many FTEs are there? 33 264 7 6 32

[(16×4)+(20×6)+(10×8)] / 8 hr/day= 33 1 FTE = 8 hour/day or = 40 hour per week use the day rate

Which of the following describes site energy? The energy product (heat or electricity) created from a raw fuel The raw fuel that is burned to create heat and electricity The total amount of raw fuel that is required to operate the building The amount of heat and electricity consumed by a building as reflected in utility bills

amount of heat and electricity consumed by a building as reflected in utility bills and is delivered to a building in one of two forms: primary or secondary energy.• Primary energy is the raw fuel that is burned to create heat and electricity.• Secondary energy is the energy product (heat or electricity) created from a raw fuel, such as electricity purchased from the grid or heat received from a district steam system. The total amount of raw fuel that is required to operate the building is referred to as "Source Energy". It incorporates all transmission, delivery, and production losses. By taking all energy use into account, it provides a complete assessment of energy efficiency in a building.

A project team decided to increase the building floor to site area ratio by building up as opposed to out. In doing so which impact category would be targeted? Enhance Human Health and Well-Being GHG Emissions Reduction from Materials and Water Embodied Energy Use Protect, Enhance and Restore Biodiversity and Ecosystem Services Reverse Contribution to Global Climate Change Promote Sustainable and Regenerative Material Resources Cycles

by decreasing footprint, more space for nature.

California has had many forest fires and the team on a project nearby wants to provide financial support for reforestation by investing in: Green-e certified renewables On-site renewable energy Carbon offsets Green power

carbon offsets, Purchasing carbon offsets helps fund projects that decrease carbon emissions or remove carbon from the atmosphere. Examples of these types of projects include reforestation, changing land-use, and methane abatement.

Why are VOCs limited? They can be sensitive to the touch They can have an unpleasant odour They can cause buildings to degrade faster They can be carcinogenic

carcinogenic

Standards are an integral part of LEED, as they avoid the need of reinventing the wheel. What are Green Seal and Environmental Choice used for? Furniture and furnishings Flooring Cleaning products Renewable energy Carpet

cleaning products. Green cleaning products have several standards depending on the type of cleaning product. Green Seal, Environmental Choice, EPA, and California Code of Regulations are a few examples.

What process uses heat recovery to capture heat from electricity generation and then turns the recovered heat into thermal energy that can be used to heat a building? Commissioning Sedimentation Cogeneration Evapotranspiration Tertiary Treatment

cogeneration: Combined heat and power (CHP), also known as "cogeneration", is an electricity generation technology that recovers waste heat from the electricity generation process to produce other forms of useful energy, such as usable heat or steam. On average, two-thirds of the input energy used to make electricity is lost as waste heat. CHP systems are capable of converting more than 70% of the fuel into usable energy.

**LEED v4 takes a new approach to the water efficiency credit category and requires which strategy/approach? Water conservation only Desalination of sea water Conservation first Capture and treat rainwater

conservation first; For both energy efficiency and water efficiency, LEED requires a conservation/efficiency-first approach. Efficiency means doing the same with less. After efficiency, the focus should then be placed on other ways to reduce demand such as rain water reuse

LeadingGreen owns 100% of the LEED® boundary. The project includes a major HVAC renovation, significant envelope modifications, and core plumbing renovation but may also allow for future tenant fit-outs. Which LEED rating system should be selected based on the 40/60 rule? LEED BD+C: New Construction LEED O+M: Existing Buildings LEED BD+C: Core and Shell LEED ID+C: Commercial Interiors

core and shell. The key terms here are envelope and core renovations. LEED Building Design and Construction: Core and Shell applies to the exterior shell of the building and the core mechanical, electrical, and plumbing units, but not a complete interior fit-out. LEED BD+C: Core and Shell is the appropriate rating system to use if more than 40% of the gross floor area is incomplete at the time of certification. LEED O+M: Existing Buildings is used for buildings that are undergoing improvement work and little to no construction. LEED BD+C: New Construction requires more than what is being completed in this project. LEED ID+C: Commercial Interiors is for an interior project that involves a complete interior fit-out. As the owner of the building, LeadingGreen would not be completing these fit-outs.

"Location, location, location!" Location is a very important item for LEED in multiple credit categories. Which location choice can unexpectedly reduce the demand for new materials in a project? A sprawled single-home residence A mixed-use development built on a greenfield A dense, mixed-use neighborhood A multi-building office project with single-story buildings

dense, multi-use neighborhood. The greater the density of a project, the more environmentally friendly it is. Putting more people into a single building is better than taking up additional land space for multiple buildings for the same number of people. A mixed-use project, such as one with apartments on top of retail stores, uses less material overall because residential and retail are not in separated into stand-alone buildings. Building fewer stand-alone buildings means fewer new materials used. Finally, dense building requires fewer roads and related infrastructure, saving more materials.

LeadingGreen is developing a new campus project in an area without zoning. When would LeadingGreen use the ITE Transportation Planning Handbook? To determine the amount of parking needed To determine transportation demand strategies To determine where to place preferred parking To determine how much vegetative space is required to meet LEED

determine amount of parking needed. For the Reduced Parking Footprint credit (LTc7) under Location and Transportation, there are three requirements:• Do not exceed local zoning code requirement• Provide 5% preferred carpool parking• Reduce parking capacity from baseline (ITE Handbook Standard)

What LEED rating system would be applicable to minor renovations in a building? LEED BD+C: Homes LEED O+M: Existing Buildings LEED BD+C: Core and Shell LEED BD+C: Schools LEED BD+C: New Construction

existing buildings.

The Green Building Information Gateway (GBIG) is a great tool to find information about buildings across America. What would a LEED Green Associate use the GBIG for? Finding the regional priority credits to pursue on a specific project Updating a project's public information Submitting LEED documentation Exploring and comparing the green dimensions of the built environment Communicating with regional USGBC chapter to determine Regional Priority credits

exploring. LEED Online is used to find Regional Priority (RP) credits, submit LEED documentation and update project information. One of the tasks of a LEED Green Associate is to create project profiles, case studies, and press releases. Part of the public relations guidelines for LEED-certified projects suggests the use of the Green Building Information Gateway (GBIG).

Which term describes the positive or negative consequences of an economic activity experienced by unrelated third parties? Ponzi schemes The Butterfly Effect The Prius Effect Externalities

Which of the following statements is FALSE regarding Environmental Tobacco Smoke (ETS) Control (EQp2)? Signage prohibiting smoking must be posted 10 feet from all entry locations Smoking is not permitted in residential projects Smoking is not permitted outside the building except in designated smoking areas Signage prohibiting smoking must be posted 10 feet from all operable windows

false: smoking is not permitted in residential projects

The EPA's WaterSense label is encouraged by LEED for all new fixtures purchased throughout the building's life. Which of the following does it apply to? (CHOOSE 3) Private/public faucets Washing machines Irrigation submeters Waterless urinals Toilets Showerheads

faucets, toilets, showerheads.

A Health Product Declaration (HPD) leads to the purchase of what kind of materials? Those that are verified to have been responsibly sourced Those that are certified by ISO 14021 Those that are more durable Those with fewer negative health effects

fewer negative health effects. Health Product Declarations (HPDs) provide a full disclosure of the potentially concerning chemicals in products by comparing a product's ingredients to "hazard" lists published by government authorities and scientific associations. An HPD itself does not indicate whether or not a product is healthy— it merely reports on the material ingredients. Armed with this information, project teams can compare the type and quantity of materials in different products and see if they contain any unhealthy materials.

When conducting a site assessment to show compliance with LEED, which of the following does not need to be included? Climatic conditions Solar exposure Financing Instruments Historical/blighted structures

financing

Which of the following statements is an accurate description of a stakeholder meeting? A meeting with everyone that has a vested interest in the outcome of a project A meeting where research is conducted about materials An intense workshop to solve a problem or plan the design of something that includes the project team and stakeholders A meeting where engineers work together to discover new synergies

first answer.

LEED v4 introduced new compliance paths for its rating systems. When would the Home Energy Rating System (HERS) Index be used? When determining the minimum energy performance of a two-story residential project During the discovery phase of water-related systems To measure how much rain runs off through 25% of the site When measuring the energy performance of an office tower During energy modeling process to determine points awarded in energy and atmosphere

first answer. The Home Energy Rating System (HERS) Index is a standard by which a home's energy efficiency is measured. Based on the results, a home will receive a HERS Index Score in the form of a miles-per-gallon (MPG) sticker, giving prospective buyers and homeowners insight as to how the home performs in terms of energy efficiency. In addition to the HERS Index Score, a home-energy rating also provides the homeowner with a detailed report regarding energy problems in the house.

What should an indoor air quality plan during the construction phase entail? Protect materials from moisture damage, flush out the building before occupancy, and restrict entry of dust Calibrate sensors and monitors, and conduct an occupant survey Conduct custodial training, use fans to blow out construction dust, and orient the building properly Flush out the building before occupancy, use low VOC materials, and monitor carbon dioxide Protect materials from moisture damage, monitor carbon dioxide, and monitor outdoor airflow

first choice. Housekeeping during the construction process keeps dust and dirt from collecting in the building and its installed systems. It is important to protect materials from moisture damage to prevent rot and mold. Protecting equipment from dust and dirt by covering openings protects the systems. A flush out runs the mechanical systems with 100% outside air to remove contaminants. Flush outs are usually done after construction is complete and prior to when the occupants move in.

Minimum program requirements and prerequisites must be met if a building wants to eventually become LEED certified. Which of the following situations would not be eligible? (CHOOSE 2) An existing building project that uses CFC-based refrigerants without having a CFC phase-out plan A new building project that uses CFC-based refrigerants An existing building with strictly natural refrigeration A building that specifies only benign refrigerants A building that has a phase out place for CFCs within 5 years of completion at a maximum of 5% leakage A new building project that uses hydrocarbons (HCs) as refrigerants

A new tenant is taking over a floor in an historic building. What does LEED recognize as sustainable flooring? (CHOOSE 2) Wood flooring that a manufacturer takes back after its end of life and refinishes Carpet certified to EPA standards Green-e carpet Ceramic tile that a manufacturer takes back after its end of life and incinerates for energy Ceramic tile that a manufacturer takes back after its end of life and recycles

first, last. Environmentally preferable products have set end-of-life paths to keep them out of the landfill when they need to be replaced. These are frequently called take-back programs. As a LEED credit, the take-back program is an example of extended producer responsibility.

A new project is being built in an area with a high number of dwelling units per acre and as a result, is within walkable proximity to a number of diverse uses, mitigating environmental impacts from: (CHOOSE 2) Groundwater pollution due to construction Greenhouse gas Water pollution and sedimentation of nearby streams Air pollution Bicycle pollution

ghg and air pollution

Refrigerant management is a large factor which detrimentally affects the environmental side of the triple bottom line by: Groundwater contamination Contributing greenhouse gas emissions Indoor carbon dioxide emissions Erosion and sedimentation of adjacent streams

ghg emissions. Refrigerants have Ozone Depletion Potential (ODP) and Global Warming Potential (GWP) due to greenhouse gas emissions. Low values of each are best when choosing refrigerants.

Green Cleaning used to be a commonly used 'Innovation in Design' point for LeadingGreen's Canadian projects. Now it is an actual credit. What standard can projects outside the United States use for green cleaning products? EN 15251:2007 Green Seal EcoWise Global Ecolabeling Network SMACNA

global ecolabeling network. Global Ecolabeling Network is for any projects outside the U.S., the ISO standard developed by the Global Eco-Labeling Network may be used instead of Green Seal Environmental Choice. EcoWise is for pest management contractors. EN 15251:2007 is one of the international indoor air quality standards that projects outside of the U.S. may use. Previous versions of the credit used ASHRAE 62.1 as the reference standard. In LEED v4, projects outside the U.S. may use European standards when ASHRAE 62.1 is not available or suitable. Green Seal is used for life-cycle assessments of products or services. SMACNA (Sheet Metal and Air Conditioning National Contractors Association) standards are used for construction activity pollution prevention.

A site assessment is a key part of the integrative design and must include the investigation of: (CHOOSE 3) Hydrology and vegetation Geology Walkability Existing cars driven on to the site Surrounding density Existing physical structure

hydrology/veg, geology, existing physical structure. A site assessment is an evaluation of an area's above ground and subsurface characteristics, including its structures, geology, and hydrology. Site assessments typically help determine whether contamination has occurred and the extent and concentration of any release of pollutants. Remediation decisions rely on information generated during these assessments.

The city of Toronto is attempting to reduce greenhouse gas emissions in its municipally owned buildings and should encourage: (CHOOSE 2) The improvement of the energy efficiency of communities Development on contaminated historical sites The use of single pane glass only The implementation of waste-to-energy programs The improvement of the energy efficiency of buildings The maximization of daylighting without modeling energy loss

improvement of the energy efficiency of communities, improvement of the energy efficiency of buildings.

How can a higher level of occupant comfort due to task lighting, thermostats, and adjustable air diffusers positively impact the Triple Bottom Line? Increased initial costs Increased maintenance requirements Less ozone depletion potential Increased occupant performance

increased occupant performance

If you show exemplary performance in the SS category where are you awarded the points? Innovation in Design Sustainable Sites Integrative Process Location and Transportation

innovation in design are extra points no matter what category/credit they are in.

What is the primary reason for performing energy audits? It is one of the MPRs To monitor energy consumption related to potable water use To capitalize on renewable energy options To inspect, survey, and analyze energy flows

inspect, survey, and analyze energy flows. An energy audit is an inspection, survey, and analysis of energy flows for the purpose of energy conservation in a building, process, or system. The intention is to reduce the amount of energy input in the system without negatively affecting the output(s). When the object of the study is an occupied building, then reducing energy consumption while maintaining or improving human comfort, health, and safety are of primary concern. Beyond simply identifying the sources of energy use, an energy audit seeks to identify energy uses that have cost-effective opportunities for energy savings.

How is Floor Area Ratio (FAR) defined? FAR is the measure of the density of residential and non-residential land-use on buildable land FAR is the measure of the density of residential and non-residential land-use on all land within the property FAR is the measure of the density of non-residential land-use on all land within the project boundary FAR is the measure of the density of non-residential land-use on buildable land

last one. The Floor Area Ratio (FAR) is an important element in LEED, as it one of the metrics used to establish density requirements for credits such as Surrounding Density. Density is a ratio of building coverage on a given parcel of land relative to the size of that parcel. Floor Area Ratio (FAR) is the density of non-residential land-use measured as the total non-residential building floor area divided by the total buildable land area available for non-residential buildings. Buildable land is the portion of the site where construction can occur, including land voluntarily set aside and not constructed on. When used in density calculations, buildable land excludes public rights-of-way and land excluded from development by codified law (e.g., set-backs). Residential buildings generally use Dwelling Units per acre to describe density

Impact Categories were developed for incorporation into LEED v4 to address which of the following? Minimum Program Requirements (MPRs) TRACI categories LEED's goals Regionalization

leed goals, of which there are 7. The more effective the credit requirements are at addressing the goals of the system, the more points it receives. The seven categories address: Climate change, Human health, Water resources, Biodiversity, Natural resources, Greener economy, and Community. The seven Impact Categories answer the question: "What should a LEED project accomplish?"

The Regional Priority credit category is specific to: LEED BD+C and O+M only LEED CIRs All LEED rating systems The LEED project type (schools, healthcare, data centers, etc.) The location of the project, determined by its zip code

leed project type. Each LEED project type has different requirements, so each rating system has its own Regional Priority (RP) credits. E.g. IAQ is more important in a healthcare facility than a warehouse, so a healthcare facility project may be able to earn points for IAQ, whereas a warehouse may not. Zip or Postal codes are no longer used to determine RP credits. Specific Geographical location found on the USGBC's website is the new method.

A project owner in Colorado is hoping to reduce the amount of potable water used for irrigation through rainwater harvesting and should first look at: The volume of rainfall The pollutants in the rainwater runoff The annual consumption of potable water on the project Local/state regulations The grading of the site

local/state regs. Regulations and rules/codes are always the first item to be looked at. For example, some water in Colorado is owned by Texas.

ASHRAE, MERV, FSC and ISO are some of the standards embedded in the LEED rating system. While MERV defines the amount of particulates allowed to pass through a filter, what helps teams with implementing in a comprehensive Integrative Process? ASHRAE Holistic Design Guide ENERGY STAR® I-Codes for Integrative Processes Integrative Process (IP) ANSI Consensus National Standard Guide 2.0 for Design and Construction of Sustainable Buildings and Communities LEED IP Help

longest answer. IP. The ANSI standard provides project teams with step-by-step guidance through the integrative process. The other options are fake or irrelevant to the IP.

If there are 3 LEED professionals, an architect, a construction person and an engineer, how can their expertise be most directly awarded in LEED? 2 Points for the integrative design process 3 Points for having 3 LEED AP+ working on the project 1 Point for a LEED consultant being involved in the project 1 Points for having a LEED AP+ working on the project

Which of the following demonstrates Systems Thinking? Researching how occupants will travel to the project Building up as opposed to out Reviewing the schedule for the timing of the HVAC system installation Building a parking structure Commissioning all building systems to reduce energy usage over time

researching how occupants will travel to the project. Systems Thinking is a process of understanding how each part of the built environment affects the other parts. It is the belief that the component parts of a system can best be understood in the context of relationships with each other and with other systems, rather than in isolation. These parts include project materials, building systems, site, people, and information. In this choice the people are considered in terms of their relationship to the transportation options and/or parking at the site.

LEED incorporates strategies and sustainable practices, such as open and closed systems, into its holistic rating system. Which of the following is FALSE in regards to a closed system in the built environment? This can be accomplished through a waste-to-energy facility if there is no waste Materials in a closed system are used for other purposes at the end of their useful life Resources that have been fully used are then released outside the system There is absolutely no waste

resources that have been fully used are then released outside the system. A closed system (A.k.a. "cradle to cradle") involves the re-use of materials at the end of their useful life, as opposed to a destructive open loop system (A.k.a. "cradle to grave") that produces waste. Sustainable buildings aspire to achieve the "cradle to cradle" system.

After substantial completion and occupancy, how can the project team maintain ongoing energy efficiency via a third party? By monitoring Building Automation Systems By comparing the building's energy performance against the ENERGY STAR Portfolio Manager By purchasing Renewable Energy Credits (RECs) Through retrocommissioning

retrocommissioning: Retrocommissioning is a commissioning process that can be performed on existing buildings to identify system improvements that will make the building more suitable for current use. Building Automation Systems (BAS) collect data about a building's systems and track it over time. The data can be used to determine trends or anomalies, which can then serve to help fix or update the systems. Purchasing RECs indirectly reduces the use of electricity produced from fossil fuels. This method would not affect ongoing energy efficiency. It may be useful to compare the building's energy performance to other Energy Star -labeled buildings using the Energy Star Portfolio Manager, but it is a completely separate tool from the LEED rating systems. The Energy Star label only applies to electronics, home appliances, and heating and cooling equipment. Energy Star -labeled buildings use about 35% less energy than traditional buildings.

ISO 14021 defines the different types of recyclable materials. Which of the following would be considered a "pre-consumer" material if it is recycled one day? (CHOOSE 3) Sawdust Coca-Cola® cans Construction and demolition debris Walnut shells Sunflower seed hulls

Soft costs: is one that is not directly related to building, construction, etc. Examples are building permit fees, architectural, legal, financing, and engineering fees, commissioning, and other costs incurred before and after construction.Hard costs: By far the largest portion of the expenses in a construction budget, hard costs are mostly comprised of the actual construction costs incurred in building the project.

The Environmental Protection Agency lists numerous ways to reduce solid waste leaving your site. Which is the priority? Recycling Reuse Recovery Source reduction

source reduction, also known as waste prevention or pollution prevention, targets waste at its point of creation, aiming to reduce waste before it is created. An example of source reduction is using less packaging to ship an item. Another is the use of dimensional lumber in the exact size needed. The four strategies preferred by the EPA for reducing waste are, in order:a. Source reduction b. Reuse c. Recycling d. Waste-to-energy
