latchset

ONLY holds door in place; NO lock (i.e. restroom partitions)

photogrammetry (drawing)

SURVEYING of objects/spaces by using photography and associated software

CAL TB133 (NFPA 266)

actual sample of furniture

organization concept: central

based on 1 space or point about which secondary elements are placed --usually very formal method of organizing interiors and inherently places primary emphasis on the central space

light source as design element

can be a point, plane, line or volume and can have qualities of brightness and color --illumination the light provides can, in turn, be seen as a point, line or plane on objects and surfaces, each with it's own brightness and color -lighting can: set/enhance the mood of an interior space, give added interest to the visual environment, accent & emphasize objects & areas, de-emphasize undesirable areas or architectural features, highlight surfaces & textures, enhance color, and affect spatial perception

how to fix reflected glare

decrease the contact between the task and its background

depth perception: texture perspective

density of a texture seems to increase as the distance from the viewer increases

one-line diagram

drawing prepared by the electrical engineer that shows a diagrammatic representation of the electrical system, from the primary feed in the building to individual lighting and power panel boxes

finish carpentry

exposed wood construction assembled AT THE JOB SITE (i.e. doors & windows, door & window trim, standard wood base & other molding, site-built stairs & handrails)

daylight factor

expressed as a %, is the ratio of the indoor illuminance at a point on a horizontal surface to the unobstructed exterior horizontal illuminance --direct sunlight EXCLUDED --range from about 1.5% to 4%

Intrusion Detection: Window screen

fine wires embedded in the screen that can be used to set off an alarm when they are broken

criteria for selection: safety/health

finish safety flammability = most important criteria mold & mildew resistance outgasing security slip resistance volatile organic compound emission

criteria for selection: cost

first (initial) cost life cycle cost

Green Label Plus

for carpets and rug

plane

form with 2 dominant dimensions, length, and width --*significant component of interior design because space is typically defined by the planar surface, such as walls, ceilings, and floors --help determine the form of the space; because of this, they are a major factor in determining the CHARACTER of a space

door and drawer front construction: flush overlay

front of door/drawer overlaps face frame of cabinet --edges of adjacent door/drawer fronts are separated only enough to allow operation without touching, usually about 1/8" or less --only doors/drawers visible and are flush with each other

criteria for selection

function durability maintainability safety/health cost

mortise lockset

installed in rectangular area cut out of door; more SECURE than cylindrical and offers wider variety of locking options

fire extinguisher type D

involves combustible metals

introduce nonintrusive background sound

may come from steady hum of HVAC systems, from business machines, traffic, conversations, etc. i.e. 75db (sound level of noise room) - 45db (transmission loss of wall) = 30db ... introduce background noise of 35db to mask sound of noisy room

elliptical reflector lamp

more efficient type of incandescent because it focuses the light beam at a point slightly in front of the lamp before it spreads out (slightly smaller spread that that of an R lamp)

space relationships: adjacent spaces

most common type of interior relationship in which each space or room has its own use and functional requirements and is separated by a partition or other construction element

cylindrical

most common; simple to install in holes drilled into door, relatively inexpensive, most common in residential (like doors in home bedroom)

blinds: plantation shutters

much wider louvers

Individual plastic-insulated conductors

must be placed in METAL conduit or other approved carriers -conduit supports and protects the wiring, serves as a system ground, and protects surrounding constructions from fire if the wire overheats or shorts

network workflow

no strictly organized method

live loads

people and furniture

perceptual: shape constancy

people perceive objects as having their original shape regardless of a change in ORIENTATION of the object or the point of view of the observer --why? because of people's memory and the brain takes into account depth of an object

brass & bronze

predominantly copper in practical use, many alloys that are really brass are referred to as bronze although corrosion resistant, it changes color with age & exposure to moisture in the air

Architectural woodwork (millwork) grades

premium: gives highest quality in materials, workmanship and installation custom: most common grade and still produces high quality job economy: defines minimum level of quality, materials and workmanship

Green Seal

promotes environmentally responsible production, purchasing, and products

Rhythm

rhythm = 1 of the most POWERFUL design principles --repetition of elements in a regular PATTERN --because it sets up a sequence of multiple elements through space, it also includes a TIME component as the eye or body moves past the individual pieces --elements follow a common baseline in which they are related either by physical connection or by an imaginary line that the eye and mind use to tie the elements together --simplest form is uniform repetition of identical objects ***a regular rhythm is often EFFECTIVE when contrasted with a unique element of EMPHASIS

Linen

seldom used for upholstery because it LACKS RESILIENCE and flexibility and susceptible to abrasion dimensionally STABLE and resistant to fading, making it usable for draperies and wallcoverings

LED

semiconductor device that uses solid-state electronics to create light --advantages: brightness, long life, and low power consumption --produce no heat and can be directly controlled by a digital interface __disadvantage: LOWER efficacy and high cost

flowchart

show adjacencies as well as the direction of movement

veneer cutting: half round slicing

similar to rotary slicing, but the log is cut in half and the veneer is cut slightly across the annual growth rings --results in a pronounced grain pattern showing characteristics of both rotary and plain sliced veneers

circulation patterns: dumb bell layout

simplest and 1 of the most flexible circulation path patterns --spaces laid out along a straight path that connects 2 major elements at the end - usually an entrance to the space or groups of rooms at one end and an exit or other access point at the other

fuzzing

small fibers work out of yarn onto the surface of the fabric

human factors: ergonomics

study of the relation between human physiology and the physical environment --uses info developed by ANTHROPOMETRICS, but goes FURTHER by studying exactly how humans interact with PHYSICAL OBJECTS, such as chairs, control panels, desks, etc.

transmission loss

takes into account ONLY the loss through the partition

coefficient of absorption

the ratio of the sound intensity absorbed by the material to the total intensity reaching the material --max. absorption possible is 1 --generally a material with a coefficient below 0.2 is considered to be REFLECTIVE and one with a coefficient above 0.2 is considered sound ABSORBING

parabolic alluminized reflector (PAR)

tighter spread than regular incandescent --* second narrowest beam spread

rentable area

total amount of usable space available, but it also includes structural columns, the thickness of some partitions, and typ. a portion of the exterior wall of the building --ALSO INCLUDES: proportionate share of the elevator lobby, the public corridor, restrooms & mechanical rooms

radiation

transfer of heat energy through electromagnetic waves from one surface to a colder surface

convection

transfer of heat through the movement of a fluid, either a gas or a liquid --occurs when air temperature surrounding a person is LESS than the body's skin temperature

volume

true 3d aspect of interior design, because an object with volume is clearly perceived as a spacial form having length, width, and depth --either be solid or void, sometimes referred to as positive or negative space, or figure-ground

radial balance

type of symmetrical balance in which elements are arranged uniformly about a central point --usually focuses attention on the center of the grouping

stainless steel

used for its corrosion resistance, strength & appearance

design theory

way to direct design based on a system of beliefs

net area

ACTUAL AREA required to accommodate specific functions (includes walls and building columns)

waffle slab concrete construction

(2 way joist); can provide support for heavier loads at slightly longer spans than flat slab -often left exposed with lighting integrated into coffers -ribs can be cut for large opening, i.e. stairs, but difficult & expensive & requires additional support around it

air temperature

**primary determinant of comfort

soft coverings: drapery

*1 of the most common types --any loosely hung fabric that covers the window --fabric attached to a traverse rod that allows it to be drawn open and closed, but many styles of hanging are possible, including fixed, tie back, and loose-hung swags **pick drapery according to flammability first, over durability, fading resistance, and style

perspective drawings

*give most accurate 2d representation of the 3d world because they use the principle of convergence, which is the apparent diminishing size of objects as they get farther from the eye -1 point perspective: when point of view is perpendicular to 1 of the planes of the object -2 point perspective: created when the point of view is at a normal eye level and is not perpendicular to any plane of the object

reducing the level of sound source

*not always possible if sound created by a fixed piece of machinery, people, etc. -source noise from outside/adjacent room? ---transmission loss of the enclosing walls can be improved ---if a machine is producing the noise, it can often be enclosed or modified to reduce its noise output

client interview

--1 of the most VALUABLE ways to collect information -combines observation, a structured process, the ability to clarify ambiguous questions or responses, & the opportunity for extemporaneous exploration of needs & ideas of the user not previously considered --verify accuracy of questionnaires --takes time

noise reduction within a space: rules of thumb

--avoid designing rooms with hard reflective surfaces on the walls, floors, and ceiling (space will be too "live" and noisy) ----- average absorption coefficient of a room should be AT LEAST .20 (average of .50 is usually NOT desirable, nor economically justified) --each doubling of the amount of absorption in a room results in a noise reduction only 3db (HARDLY NOTICEABLE) -----to make any difference, the total absoprtion must be increased by at least 3 TIMES to change the reduction by 5 DB, which is noticeable --although absorptive materials can be placed anywhere, ceiling treatment for sound absorption is more effective in LARGER rooms, while wall treatment is more effective in SMALL rooms

observation

--one of the most reliable ways to gather information to see what people do rather than by listening to what they say --DANGEROUS, however, because you may jump to conclusions without understanding why people are doing things in a particular way --best used to verify information gathered by interviews or questionnaires or as a way of generating questions to determine reason behind observed behavior

effect of color: complementary colors

--reinforce each other (high contrast) --when 2 complementary colors are seen adjacent to eachother, each appears to heighten each other's saturation --when used together in a scheme, large areas of color are generally a low chroma (more gray) and are a tint or shade of the color while smaller areas/accents have a higher chroma --when 2 NONcomplementary colors are placed together, each appear to tint the other with its own complement (result: 2 colors will seem farther apart on the color wheel than they really are)

HID lamps

--require time to restart after being shut off or in case of power failure

brightness rations

-3:1 = between task and IMMEDIATE backgrounds -5:1 = between the task and NEARBY general surroundings -10:1 = between task and more REMOTE surroundings

effect on color on SPACIAL perception

-bright warm colors: tend to make an object appear LARGER -dark color: make an object look SMALLER and HEAVIER -light, neutral color: extend the apparent space of a room while dark values make a space feel closed in -warm colors advance, cool colors recede

particleboard

-composed of small wood particles, fibers, and CHIPS of various sizes mixed together in a binder and formed under pressure into a panel -commonly used as a SUBSTRATE for natural and laminate veneers in architectural woodwork construction (i.e. casework not built on site) -most common, dimensionally stable; smooth surface; impact resistance

shades: roller shades

-consist of a piece of cloth wound around a spring roller ----normally pulled closed from the top but can also be mounted so a pully-mounted cord unwinds them from the bottom up ----inexpensive & can be covered in decorative fabric ----block view when closed & can interfere with ventiliation ----block light unless made from a translucent material

pre-cast concrete system (as a whole)

-consists of factory made pieces -high-strength steel cables are stretched in the precasting forms before the concrete is poured -after concrete attains a certain min. strength, the cables are released and they transfer compressive stresses to the concrete -popular form because they can simultaneously serve as beam and floor decking and are easy/fast to erect

performance (open) spec

-descriptive: gives detailed written REQUIREMENTS for the material product and the WORKMANSHIP required for its fabrication and installation; does NOT mention tradenames -reference standard: variation of the descriptive spec type that describes a material, product, or process based on requirements (REFERENCE STANDARDS) set by an accepted authority or test method (can be made to trade associations) -pure performance: statement setting criteria and results required of an item being specified (results verified by measurements, tests, etc.)

proportion: modular system

-developed by Le Corbusier, it is loosely based on the golden section but uses the HUMAN BODY as the starting point --system begins by dividing the height of a man, about 6', at the waistline or navel --another proportion is developed by the distance from the top of the head to the fingertips when the arm is naturally raised above the head --distance from the bottom of the feet to the navel is equal to the distance from the naval to the raised hand DIVIDED by the dimension from the top of the head to the raised hand = GOLDEN SECTION

pre-cast concrete floor

-double t: commonly found in industrial buildings, one & two story commercial buildings, and parking garages (stems deep and contain prestressed cable, they CANNOT be CUT; so opening is limisted to areas between t sections -hallow core: small opening can be cut thru the existing cores but should not be cut thru the solid portion where prestressing cables are located

selecting fabrics: important criteria

-durability -resistance to abrasion = MOST IMPORTANT -flammability = also one of the most important considerations -maintenance -appearance -scale -comfort -touch -wearability

Site Analysis: LEED

-during site analysis, interior designer should determine if the building owner or client is interested in applying for a LEED rating -certified, silver, gold, or platinum

Types of Hinge Tips

-flat button (most common; typical) -hospital -oval head (typical) -steeple -flush

behavior settings: proxemics distances

-intimate (6-18") -personal (18"-48") -social: most impersonal business, work, and other interaction takes place between strangers or in formal situations (48"-84"; 84"-144") -public distance (144" and beyond)

open web STEEL joist system

-joists span between beams or bearing walls -steel decking spans between joists and a concrete slab is poured on top of the decking (EASY to penetrate holes) -one-story/low rise buildings with wide column spacing -because webs are open, mech. and elec. service ducts, pipes, and conduits can easily be hung from the bottom of the joists

steel beam & girder system

-large members called GIRDERS span between columns and small beams are framed into them -girders span SHORT DISTANCE because they carry the weight of the beams (beams span longer distance because they frame into the girders) -framing is usually covered with steel decking, which spans between the beams, then concrete topping is poured over the decking to complete the floor slab (EASY to penetrate holes) -found in MID to HIGH rise office buildings -usually LIMITED SPACE between the bottom of the girders and the suspended ceiling (possibility of adding new mech. ductwork or installing large recessed light fixtures should be reviewed before final decisions are made)

incandescent

-low efficacy -2700-2800K *-100 CRI -Low lamp life -inexpensive, compact, easy to dim, can be repeatedly started without a decrease in lamp life & have a warm color rendition DISADVANTAGES: low efficacy, short lamp life, and high heat output

plywood

-made from an odd # of layers of thin veneer glued together under heat & pressure -used in FINISH carpentry (door trims, etc.)

MDF

-made from wood particles REDUCED to fibers (fluff) in a moderate-pressure stream vessel and then combined with a resin and bonded together under heat and pressure -most DIMENSIONALLY STABLE -used for painting, thin overlay materials, veneers and high pressure decorative laminate, shelving, molding, and furniture

circuiting

-many lights connected to a dimmer must be on their own circuit -incandescents should be on a different circuit than fluorescents (120v vs. 277v)

Romex

-nonmetallic sheathed cable -consists of 2 OR MORE plastic insulated & ground wire surrounded by a MOISTURE-RESISTANT plastic jacket -can be used in WOOD STUD residential building & buildings not exceeding 3 floors as long as it is used with wood studs and protected from damage by being concealed behind walls & ceilings

Flame properties of fabric

-nylon and wool will burn when in flame but are SELF-EXTINGUISHING when removed from flame -olefin and cotton continue to burn when removed from flame

Nylon

-one of the MOST POPULAR synthetic fibers -exceptionally strong with high resiliency and elasticity -resistant to many chemicals, water, and micro-organisms --flame resistant (not as much as wool, silk, and modacrylic) *often combined with other synthetic/natural fibers to obtain superior advantages of both

social and cultural belief influences

-political conditions: prevailing political attitudes and policies may affect design -economic conditions: state of economy often reflected in architecture & design -cultural attitudes: views of family, shared values, religion, fashion, leisure pursuits, sports, etc. -symbolism: physical environment holds a great deal of symbolism for people -regionalism: design that reflects the local geographic area

prescriptive (closed) spec

-proprietary: call out SPECIFIC manufacturer's product; no competitive bidding allowed -base-bid (equal): calls out proprietary material or product but allows the SUBSTITUTION of other products that the contractor thinks is equal ----variation: list several approved manufacturers or base-bid spec with "approved equal"

principles of gestalt pyschology

-proximity -similarity -direction -context -closure (tendency to perceive incomplete forms as complete) -continuity -simplicity (people prefer simplest, most stable organizations of forms or overall structure) -figure-ground

vertical stack

cast-in-place concrete (as a whole)

-utilize only MILD steel reinforcing set in the framework before concrete is placed -sometimes with long span structures: post tensioned: steel cables within the concrete are tightened after the concrete sets, creating extra compression forces into the beam or slab (SHOULD NOT be penetrated with holes/conduit)

noise reduction coefficient of materials

-vinyl tile on concrete = .05 -wood strip flooring = .10 -carpet, 1/2" pile on concrete = .50 -gypsum walls = .05 -1" fiberglass wall panel with fabric cover = .80 -plywood paneling = .15 -5/8" suspended acoustical ceiling tile = .60 1" suspended acoustical tile = .90

winding vs. curved stairway

-winding: tapered treads that are wider at one end than the other -curved: SIDES whose SHAPE is a curve (inside smaller arc cannot be less than twice the required width of the stair or it is winding)

Fire rated glazing

-wired: mesh of wire embedded in the middle of the sheet; NOT tempered & doesn't qualify as safety glazing for hazardous locations -tempered, fire protective glass -glass block

Loudness vs. decibels

1 = almost imperceptible 3 = just perceptible (doubling) 5 = CLEARLY NOTICEABLE (3 times as much) 6 = change when distance to source in a free field is doubled/halved 10 = twice/half as loud 18 = very much louder or quieter 20 = 4 times or 1/4 as loud

methods to build a sound-resistant partition

1. add mass to the wall (use heavy material for the partition, i.e. masonry or by using more than 1 layer of gypsum wallboard 2. place insulation within the stud cavity 3. resilient channels used as furring strips on 1 side of the partition

2 methods used to measure speech privacy in open offices

1. articulation class: how effective a CEILING is in absorbing sound reaching it from over LOW PARTITIONS (uses 9' high ceiling and 60" high partitions) 2. articulation index: measures the performance of ALL the elements of a particular CONFIGURATION working TOGETHER, including ceiling absorption, space dividers, furniture, light fixtures, partitions, background masking systems, and HVAC sound --all predicts the intelligibility of speech for a group of talkers and listeners --rating between 0 and 1 (1 = no privacy) --confidential speech = below .05 --normal speech: between .05 and .2 --UNACCEPTABLE level of privacy = .30 and ABOVE

Maslow's Hierarchy of Needs: Deficiency Needs Levels

1. basic needs: food, water, minimal body comforts 2. safety needs: protection, avoidance of personal harm 3. belonging and love needs 4. Self Esteem (i.e. achieve, be competent, and gain approval and recognition by others)

extent of direct glare problem depends on what?

1. brightness of the source 2. its position 3. the background illumination 4. the adaptation of the eye to the environment

5 important factors to achieve speech privacy in an open-plan office

1. ceiling must be highly absorptive ("clear sky" condition = sounds not reflected) 2. area must include space dividers that reduce the transmission of sound 3. other surfaces, such as the floor, furniture, windows, and light fixtures, must be designed or arranged to minimize sound reflections 4. if possible, activities should be distanced to take advantage of the normal attenuation of sound with distance 5. area should have a properly designed background masking system

3 performance criteria for foam cushions

1. density 2. indentation load deflection (ILD): firmness 3. support ratio (ratio of force required to compress foam)

process of developing/reviewing a detail is a way of satisfying the requirements of 4 categories, what are they?

1. design intent 2. constraints 3. function 4. constructability (can't do this one until the other 3 are accomplished)

light quality factors

1. direct glare 2. reflected glare 3. contrast 4. uniformity 5. color 6. efficacy (ability to produce a desired/intended result; how well a light source produces visible light)

5 step programming process

1. establishing goals (what does the client want?) 2. collecting & analyzing facts (describe existing conditions and requirements of the problem; i.e. space adjacency, equipment needed, expected growth rate, etc.) 3. uncovering & testing concepts (ABSTRACT ideas that are functional solutions to the client's performance problems, without defining the physical means that could be used to solve them) 4. Determine needs (balance desires of the client against the available budget or establishes a budget based on defined goals & needs) 5. Stating the problem (the bridge between programming and the design process)

flexiblity

1. expandability (accommodate growth) 2. convertability (allow for changes in function) 3. versatility (different activities with multifunctional spaces)

4 major considerations during programming

1. form (relates to existing conditions of the space, the physical & psychological environment of the interior, and the quality of construction) 2. function (relates to people using the space, the activities to be performed there, and the relationship of spaces to eachother) 3. economy (concerns money) 4. time (describes ideas of the past, present, and future as they affect the three other areas)

critical VARIABLES in the control of sound transmission

1. gaps in the barrier must be sealed 2. edges at the floor, ceiling, and intersecting walls must be caulked 3. penetrations of the barrier should be avoided or at least sealed well ---i.e. electrical outlets should not be be placed back to back but staggered; pipes, ducts, etc. should not be rigidly connected to barrier (gaps sealed and caulked) 4. construction with a lower sound transmission class than the barrier itself should be avoided 5. doors should be heavy and sealed with weather stripping with a threshold or automatic door bottom --if glass used, make sure its laminated with resilient framing 6. flanking paths for sound travel, i.e. AC ducts, plenums and hallways should be eliminated or treated appropriately

information gathering

1. interview 2. questionnaires 3. observation 4. field surveys

how to determine square footage (3 ways)

1. multiply area 1 person needs by total number of people in same area OR based on something that is directly related to the occupancy rather than the # of people (i.e. restaurant kitchen is a percentage of the size of the dining space) 2. by the size of an object or equipment 3. defined through a built-in set of rules or customs related to the activity itself

detailing serves to meet 1 of 3 objectives

1. must resolve how to physically connect the various components of a design 2. solves functional problems 3. way to enhance the design intent of the project and contribute to the overall look/style of the project design

2 interviewers always present: why?

1. one person to ask questions and the other to observe and take notes 2. provide a 2nd opinion

3 basic types of adjacency needs

1. people 2. products (movement of objects facilitated) 3. information

planning concepts in regard to noise

1. plan similar use areas next to each other 2. use buffer spaces such as closets and hallways to separate noise-producing spaces whenever possible 3. stagger doorways in halls and other areas to avoid providing a straight line path for noise 4. locate furniture and other potential noise-producing objects away from the wall that is separating spaces 5. minimize area of the common wall between the 2 rooms where a reduction in sound transmission is desired 6. avoid room shapes that reflect or focus sound

sound transmission: 2 basic problems in controlling noise

1. preventing/minimizing the transmission of sound from one space to another 2. reducing the noise within a space

how to control sound control in a room (3 ways)

1. reduce level of loudness of sound space 2. modify absorption in space 3. introduce non-intrusive background sound to mask unwanted sound

Butt Hinge

MOST COMMON; has both leaves fully mortised into the frame and the edge of the door so the hinge is flush with the surface of the frame and door

background noise

NOISE CRITERIA CURVES can be used to specify the max. amount of this in order to establish a min. amount of noise desired to help mask sounds, and to evaluate an existing condition

programmatic concept

PERFORMANCE requirement related to methods of solving a problem or satisfying a need --developed ideas about how to view & solve client's PERFORMANCE problems

avora fr

POLYESTER yarn that uses modified polymer so it is PERMANENTLY flame resistant regardless of wear and number of washings --easy to clean, abrasion resistance, crease proof and dimensionally stable --DOES NOT retain odors and support bacteria

Rayon

POOR RESISTANCE to SUNLIGHT & poor resiliency (stretchy), high absorbency, low resistance to water and moisture **FLAMMABLE *seldom used for upholstery

Gypsum Drywall Edges

Tapered: Most common; tapered on face side along the long dimension of the panel & square edges at the end; allows for application of reinforcing tape & joint compound without causing bulges at joints Square: used where appearance is NOT a factor, for basic layers of 2-layer applications & for veneer plaster work

Most resistant to fire when UNTREATED

Wool! (least?: cotton, linen, rayon)

oblique drawings

a 3d view of an object where 1 plane of an object is parallel to the picture plane while a 3rd axis is oblique to the picture plane --shows 1 plane of an object (2 dimensions) in TRUE SHAPE and scale, with the 3rd dimension indicated by lines at a fixed angle to the true plane --advantages: existing ORTHOGRAPHIC floor plan can be used as the starting point without any redrawing; just tilt the plan at any desired angle --3rd dimension is created by projecting vertical lines (and drawn at 1/2-3/4 of the scale of the true plan)

split complementary

a color on 1 side of the color wheel is used with 2 hues that lie on either side of the complementary color

depth perception: interposition

a distant object may appear to be OVERLAPPED and partly HIDDEN by a closer object

clearance

a gap or space designed to allow for the construction or installation of a material, construction element, or piece of equipment --details must provide enough clearance to make construction possible

behavior settings

a particular place with definable boundaries and objects in which a standing pattern of behavior occurs at a particular time --useful concept for studying effects of the environment on human activity --behavior meeting (i.e. weekly meeting in conference room), useful for interior designers because it connects the strictly behavioral aspects of human activity with the effects of the physical environment on people

point

a position with no dimension --perceived when a 2d perceived object appears relatively small in relation to the plane against which it is seen --2 points create both a distance between them and an implied direction between the points as well as an implied direction between the points perpendicular to the imaginary line connecting them

proportion: Fibonacci series

a sequence of numbers beginning with 0 and 1, where each successive number in the series is the sum of the previous 2 --when any number is divided by the previous term, the quotient approximates the golden ratio; as the numbers get larger, the quotient gets closer to the value of the golden ratio

proportion: Golden Ratio

veneer cutting: rift slicing

accomplished by quartering a log and cutting at a 15 degree angle to the growth rings --like quarter slicing, it results in a straight-grain pattern and is commonly used with oak to eliminate the appearance of marking perpendicular to the direction of the grain

Maslow's Hierarchy of Needs

according to theory, humans have a variety of needs, which Maslow divided into 2 groups: 1. deficiency needs & 2. growth needs --the most basic needs must be met first before the person can move to the next highest level of needs satisfaction --meeting needs and moving to the next level proves motivation for behavior

criteria for selection: function

flame detector

responds to infrared or ultraviolet radiation given off by flames --do not give an early warning of smoldering fires

ionization detector

responds to products of combustion-ionized particles rather than smoke --not appropriate where fires may produce a lot of smoke but FEW PARTICLES --considered early warning detectors

photoelectric detectors

responds to smoke, which obscures a light beam in the device --useful where potential fires may produce a great deal of smoke before bursting into flames

space relationships: spaces sharing a common space

retain their unique identity and are linked with a 3rd space that has its own identity **most common variation of concept is corridor being used as the common space

locking mechanism: electrical lock

retracts the bolt when activated from the SECURE side of the door --unlatching from the inside is done by a button/switch/mechanical retraction of the bolt with the lever handle (i.e. AGD doors)

sense when a window has broken or been cut; either by using metallic foil or with a small vibration detector mounted on the glass

flat slab concrete construction

similar to FLAT PLATE, except drop panels (increased slab thickness around the columns) are used to increase strength --because of the closely spaced reinforcing required, often DIFFICULT but NOT impossible to drill these types for electrical service or small pipes

HID: Metal Halide

similar to mercury except halides of METALS are added to arc tube --increase efficacy and improves color rendition but DECREASES lamp life --***provide best combo of features of HID lamps (color rendering indexes between 60 and 90), high efficacy, and relatively long lamp life) DISADVANTAGE: experience a large shift in color temperature over their life

orthophotography

similar to rectified, except that is relies on DIGITAL photography and correction of optical distortion through computer software -technology of correcting aerial photographs so that displayed distances are uniform and can be measured like MAP (flat)

veneer matching method: matching veneers within a panel: BOOKMATCHED RUNNING MATCH

simply alternates bookmatched veneer pieces (all the veneer leaves), regardless of their width or how many pieces must be used to complete the panel --any portion left over from the last leaf of one panel is used as the starting piece for the next

ceiling attentuation class (CAC)

impact insulation class (IIC)

single number rating of a floor/ceiling's impact sound performance --value can be increased MOST EASILY by adding carpet -----also improved by providing a resiliently suspended ceiling below, floating a finished floor on resilient pads over the structural floor, or providing sound-absorbing material (insulation) in the air space between the floor and the finished ceiling above

noise reduction coefficient (NRC)

single number rating of the average sound absorption of a material over a limited frequency range --range from 0 to 1.0, where acoustical ceiling tiles are usually a .65-.90 *.85 or higher is recommended in open-plan offices (for ceiling tiles)

preliminary sustainability decisions during site analysis & programming

site selection or selection of building in which tenant or interior design project will be located, stormwater management plan implemented already, shade provided and/or use of light-colored/high-albedo materials and/or uses open-grid pavement, has a minimum of 50% of its parking spaces underground or covered, where roofing has high solar reflectance index or a green roof of both, whose exterior lighting does not create light pollution, uses high-efficiency irrigation, does not have a permanent landscaping irrigation system, that reduces the use of municipally provided potable water, supplies at least 5% of its total energy use through on-site, renewable energy, is in an established, walkable community, close to a residential zone and to pedestrian access to 10 basic services, close to a commuter place, provides secure bike storage, changing & shower facilities; parking at min. (encourage car pools, etc.)

field surveying should determine the following:

size & configuration of existing building/space, existing nonloadbearing partitions, cabinetry & built-in items, location & size of doors & windows, type & height of ceiling, location of electrical & telephone outlets that will be retained in new space, location & size of heating diffusers, radiators, etc., location of plumbing fixtures & plumbing PIPES, location & type of artificial lights, conditions and CAPACITY of electrical, plumbing, heating, & other mechanical systems in older buildings, general conditions of construction elements, location of true north & notes on quality & amount of natural light, views from windows, potential noise problems, special architectural features, and potential environmental problems

concrete beam & girder

slab supported by intermediate beams, which are carried by large girders -easiest to penetrate with small core drilling for pipes & poke through electrical outlets (less reinforcing than others)

casters

smooth, friction-free movement

impact noise

sound resulting from direct contact of an object with a sound barrier, can occur on any surface, but it generally occurs on a floor and ceiling assembly --usually caused by footfall, shuffled furniture, and dropped objects

lockset

special mechanism that allows the door to be locked with a KEY or THUMBTURN

texture

surface quality of a material --results from inherent structure of the material or from application of some type of coating over the material --perception of texture closely tied to the texture's visual qualities, the relationship of the texture with surrounding textures, the viewing distance, and the lighting --affected by scale relationships to nearby textures --changes based on viewing distance --light alters apparent texture (diffuse and strong, direct wash out texture) -texture: adds interest to a space, reinforces design concepts, helps differentiate objects & surfaces from each other, modulates light, and adds scale

integrated ceilings

suspended ceiling system specifically designed to accommodate acoustical ceiling tile, light fixtures, supply & return air grilles, fire sprinklers and partition attachment in a CONSISTENT, UNIFIED way all proprietary systems intended to be used in commercial applications where the partition lights & other elements connected to the ceiling change FREQUENTLY all components designed for max. REUSABILITY & FLEXIBILITY

design concepts

takes into account existing space within which the designer must work, its size, shape, entry points, windows, and other fixed elements

effect of color: primary colors

tend to appear tinted with the 3rd primary

balance

the arrangement of elements in a composition to achieve visual equilibrium --depends on the idea of visual weight (to the human eye, some elements appear "heavier" than others by the nature of their size, shape, complexity, color, texture, or location in space" --depends on both the object weight and placement

contrast

the juxtaposition of dissimilar elements --way we perceive the difference between things, create importance, and add interest and variety to our environment

transmission loss and noise reduction is primarily retarded by what?

the mass of the partition **stiffness and rigidity is also important but not as much

shape

unique characteristic of an object or space that defines it as distinct from adjacent objects or spaces --clearly distinguished by planar and volumetric forms and can be geometric (like a square, circle, or cylinder), irregular, or natural --*can convey powerful, symbolic or emotional qualities; i.e. cross, apple, etc.

access control devices: numbered keyboards

unlock a door when a user enters the correct numerical code

gore seating protection

upholstery fabric lamination and treatment process that applies a breathable moisture barrier to the back of a fabric and a topical coating to the front of a fabric

locking mechanism: electric bolt

upon activation, bolt retracts, allowing normal operation of door --fail safe feature retracts bolt if there is a power failure or upon activation of a fire alarm --cannot be used on EXIT DOORS

terminal reheat system

use ductwork for supplying fresh air but use water to heat and cool air before it is introduced into the conditioned air box contains a hot-water coil (COPPER PIPE) that provides additional heat to the air stream

fixed coverings: curtains

use fabric, usually hung within a window frame and close to the glass --not intended to be open, but meant to remain fixed across all or portion of the window

veneer matching method: matching panels within a room: SEQUENCE MATCH

use panels of uniform width MANUFACTURED for SPECIFIC JOB and with the veneers arranged in a sequence --if some panels must be trimmed to fit around doors/other obstructions, there is a moderate loss of grain continuity

all water heating system

use some type of coil unit called a convector (a unit or device that radiates heat from water to the surrounding air, usually through closed spaced fins placed against a wall under a window) in each space through which hot water is circulated -hot water heats the fins of the coil unit and the air is heated as it is drawn over the fins -for heating & a separate duct system for ventilation and cooling

Acrylic

used as a replacement for wool because of appearance --okay strength and resilience, VERY resistant to sunlight **FLAMMABLE

Intrusion Detection: Magnetic Contacts

used to purposely introduce carefully controlled sound into a space rather than rely only on random background noise --often used in open offices to provide speech privacy & to help mask office machine noise

STC (sound transmission class)

used to rate the transmission loss of CONSRUCTION --the higher the stc rating, the better the barrier is in stopping sound

raised barrel hinge

used when there is not room for the barrel to extend past the door trim; OFFSET to allow one leaf to be mortised into the frame (kind of has an L shape on each side)

halogenated agents (halon)

used where water might damage the contents of a room, like in computer installations

stereophotogrammetry (stereo- = solidity)

electronic distance measurement

uses LASER-BASED instrument with an ONBOARD COMPUTER to measure the distance, horizontal and vertical angles of the instrument's laser beam to a reflective prism target --1/64" accuracy

HID: Ceramic Metal Halide (CMH)

uses a ceramic arc tube rather than a quartz tube, which allows the lamp to burn at a higher temperature, improving color rendition and light control --efficacy better than metal halide, and there is better color consistency over lamp's lifetime --**useful in high ceiling spaces where long life and high efficacy are desirable and in retail uses where point source control and excellent CRI are needed DISADVANTAGE: higher initial cost, difficult in dimming, and requirement of a ballast

centralized plan arrangement

uses a single, dominant space with secondary spaces grouped around it --nondirectional and focuses attention on the central space --may have symbolic or functional importance

rectified photography

uses large-format, FILM-BASED view cameras to photograph FACADES --camera's focal plane is set parallel to the facade and gives a flat image with no perspective distortion --dimensions can be scaled off image, but to improve accuracy, the building plane should be relatively FLAT

laser scanning

uses medium-range, pulsing laser beams, which systematically sweep over an object or space to obtain 3d coordinates of points of the surfaces of the object/space being scanned --resulting image is a "point cloud" forming a 3d image

convergent photogrammetry

uses multiple, OBLIQUE photographic images (surveying of objects/spaces but with multiple images) taken at different angles --measurements and 3d models are derived by using software that traces the multiple overlapping photos taken from different angles --required REFERENCE POINTS

veneer matching method: matching veneers within a panel: BOOKMATCHED BALANCE MATCH

utilizes veneer pieces (grouping of veneer leaves) TRIMMED to equal widths in each panel

noise criteria curves

variable consolidated into a set of noise criteria curves relating frequency in 8 octave bands to noise level --concert halls, opera houses, recording studios = 15-20 db --bedrooms, apartments, hospitals = 20-30 db --private offices, small conference rooms = 30-35 db --large offices, retail stores, restaurants = 35-40 db --lobbies, drafting rooms, lab work spaces = 40-45 db --kitchens, computer rooms, light maintenance shops = 45-50 db

veneer matching method: matching between adjacent veneer leaves: BOOKMATCHING

veneers are SLICED off the LOG and every other piece is TURNED OVER so that the adjacent leaves form a symmetrical grain pattern

dead load

vertical loads due to the weight of the building & any permanent equipment (i.e. columns/beams, exterior & interior walls, floors, chandeliers and mech. equipment)

Silk

very STRONG and has good RESILIENCE & flexibility; very expensive and DEGRADES in SUNLIGHT *flame resistant (not as much as wool)

presentation models

very detailed and accurately represent the furniture, details, colors, and finishes --most often used for FINAL, formal client presentations and usually made by a professional model builder

axonometric drawings

view of an object inclined to the picture plane in such a way that the 3 principle axes are FORESHORTENED; quick & easy to draw; drawn by omitting parts of room --isometric: object is tilted/oblique to picture plane; 3 principle axes of object make EQUAL angles with the picture plane or drawing surface ------result: vertical axis of an object is vertical on paper and 2 horizontal axes form angles of 30 degrees on paper; lengths of all 3 principle axes are drawn at the same scale --dimetric: 2 of the principle axes are foreshortened --trimetric: all three of the principle axes are foreshortened

orthographic projection

view of an object seen as though the viewer's line of sight were simultaneously perpendicular to every point on the nearest face of the object (i.e. elevation, floor plan, etc.) --all pieces are shown in their true relationships with other pieces & scale and proportion are the same for multiple views of the same object --no distortion for lines & planes parallel to the plane onto which view is projected --diagonal line/plane shown will be FORESHORTENED

area or room protection: photoelectric beam

warn of intrusion by sending a pulsed infrared beam across a room; if beam is broken, device sounds an alarm or sends a signal to a monitoring system

Green Format

web-based database developed by the CSI to allow manufacturers to self-report sustainability properties of their products using a standard questionnaire format

welt cording

welt: fabric covered cord sewn into the seam of upholstery for ornamental purposes or to improve durability of covering **avoid where cigarettes may be dropped

depth perception: size clues

when 2 objects are the same size, the more distant one will make a smaller image on the retina than the closer one

organization concept: radial

when more than 1 linear organization extends from a central point

rhythm: gradation

where size, color, or value of design elements are gradually modified as the elements repeat

lateral loads

wind & earthquake loads

LEED: brownfield site

with certain legal exclusions, commercial or industrial property where developing, expansion, or reuse may be complicated by the presence or potential presence of a hazardous substance, pollutant, or contaminant)

emphasis & focus

within any interior, there are some elements that are more important than others -how to create: 1. part of interior can be located in an important position, 2. can be centered, placed at the termination of an axis, 3 or offset by a rhythmic grouping of other elements --or created by a noticeable contrast between it and its surroundings

centralized workflow

work is controlled from 1 central position

linear workflow

work well in long, narrow space or space where line can be folded --work or business process proceeds from one location to another in a strict sequence

drainage in plumbing

work with GRAVITY so it must be SLOPED downward to carry away waste -vent pipes required

questionnaires

written forms that people fill in with requested information --useful when a large number of people need to be surveyed and the time or resources do not allow for individual interviews
