Q

A soils report ha indicated that the water table is 5’0” above the basement level of a planned three-story building. What type of construction technique most likely will be required?

A. Dampproofing
B. Surcharging
C. Waterproofing
D. Waterstopping

A

C - Waterproofing is the control of water and moisture that is subject to hydrostatic pressure. It can refer to the application of watertight membranes, waterstops, or bentonite panels when building below the water table.

Dampproofing is the control of water and moisture when hydrostatic pressure is not present.

Surcharging is the preloading of the ground with fill material to cause condolidation and settlement of the underlying soil. Surcharging is used to increase the bearing capacity of soil or decrease the possible settlement, or both. A waterstop is a preformed piece of material used to seal construction joints. Although waterstops would be used in this situation, they are a subset of the larger requirement of waterproofing the entire basement slab and a portion of the basement walls.

Q

A deep excavation for a high-rise building in an urban area would require

A. battered walls
B. needle beams
C. steel sheeting
D. tiebacks

A

D - A deep excavation would require the used of vertical soldier beams supporting horizontal timber breast boards or cribbing. The vertical soldier beams must be anchored into the adjacent earth with grouted tieback rods. Even steel sheeting would require tiebacks for support.

A battered wall is simply a type of retaining wall using a material, such as stones or brick, slighting angled to support the adjacent earth. It is not appropriate for a deep excavation wall in an urban area where space is limited. Needle beams are used to temporarily support a structure when its foundation is repaired or deepened. Steel sheeting requires the use of rakers that extend into the excavation site, limiting the depth of the excavation and interfering with construction activities in the excavated area.

Q

A soils report indicates that bentonite is present below the site of a proposed two-story manufacturing building. What type of foundation system should be used?

A. drilled piers with grade beams
B. raft foundation
C. caissons with pile caps
D. extended spread footings

A

A - Bentonite is an expansive type of clay that can push foundations and floor slabs upward when it gets wet. To prevent this, drilled piers are used to support the building weight on bedrock or stable soil below the bentonite. Grade beams span continuously between the piers and transmit building loads from the superstructure to the piers. Voids are left below the grade beams to allow the bentonite to expand without transmitting uplift forces.

A raft foundation is use to distribute a building load over a large surface area of low-bearing capacity soil. Caissons with pile caps are used to distribute a load from one column to two or more caissons or piers and would only be appropriated if there was a void below the pile cap. Spread footings placed on bentonite would be subject to the uplift of the swelling clay soil and would not be appropriate.

Q

On a site with extensive development of buildings, roads, and parking, which change in drainage would have the most significant negative impact?

A. Decrease in pervious paving
B. increase in water held on site
C. increase in the number of drainage grates
D. increase in the overall runoff coefficient

A

D - The runoff coefficient is the fraction of total precipitation falling on a surface that runs off the surface or is not absorbed into the ground. Although the runoff coefficients may vary slightly depending on the types of paving materials used, on a site with a great deal of hard-surface development, more stormwater would have to be diverted to a storm drain system or to natural waterways. It is preferable to minimize the amount of water allowed to run off of a site.

From the information given in the problem statement, it is not clear whether or not pervious paving would be used. With a large amount of hard-surface development, the amount of water held on site would decrease, rather than increase. The number of drainage grates would most likely increase, but this is not the most significant problem.

The runoff coefficient is used to calculate the amount of runoff a cubic feet per second on a site. The calculation takes into account the rainfall intensity and the area of the site. The runoff coefficient value ranges from almost Zero for wooded areas with spongy soil to 1.0 for totally waterproof surfaces.

The formula is Q = CIA, where C is the runoff coefficient, I is the rainfall intensity in inches per hour, and A is the area of the surface in acres.

Q

Several sites are being considered for the construction of a new community college. The most appropriate site would be the one adjacent to

A. two major intersecting highways
B. libraries and shopping
C. a technology-oriented office campus
D. a residential neighborhood and public transportation

A

A - A community college is a regional resource and would benefit from easy access to transportation sources encompassing a wide areas, which two highways would provide.

Although public transportation is also a requirement, a large-scale development like a community college would not be appropriate for a residential neighborhood.

This problem requires an understanding of whether the proposed land use is local, district, or regional in nature and what the compatible uses are. A locally based project, such as a branch library or church, is compatible with residential uses and pedestrian transportation, while regionally based projects require public or vehicular transportation.

Q

Which of the following design features would have the most detrimental effect on the environment of the surround neighborhood in an urban setting?

A. square building shape.
B. dark exterior colors
C. extensive exterior paving
D. reflective glass

A

D - Reflective glass would subject the surrounding buildings, streets, and pedestrian areas to harsh reflective light and heat during most of the day. Moreover, it would affect the surrounding areas throughout the day and during all times of the year.

A square building shape would not have much of an effect other than to cast a shadow during the day. Dark colors would generally absorb heat and affect the building itself more than the surround environment or microclimate. Extensive exterior paving would tend to absorb heat and affect the mircoclimate, but primarily in the immediate area of the paving.

Q

With regard to the theories of proxemics, which approach to the design of a plaza would probably accommodate the most people while allowing individuals to maintain comfortable personal space distances?

A. large, flat, open space with trees defining the perimeter
B. heavily landscaped area with areas of lawn
C. amphitheater with bench-type seating in raised tiers
D. space with various levels, benches, and spaces defined by low walls.

A

D - Proxemics is a term used by Edward T. hall for his theory of cultural use of space. Proxemics deals with issues of territoriality, spacing and positioning between people, and how the organization of the environment can affect these issues.

When designing a plaza that could accommodate a large number of closely spaced people, the designer may incorporate features that provide a sense of territoriality, encourage actual or imagined separation, and offer a choice of various spatial positions. These elements could be provided by using design features such as changes of level; juxtaposition of open spaces and spaces defined by street furniture, landscaping, and low walls; landscape areas not intended for occupancy; and individual seating. This design could be flexible enough to accommodate a large number of people when required for large events, or could be used for individual groupings of people.

A large, open space would encourage individuals and small groups to spread out rather than feel at ease nearer together. A heavily landscaped area would be attractive and would help define separate spaces for people to gather, but may limit the greatest number of people from assembling. An amphitheater would accommodate a large number of people but would be limited in flexibility for other types of informal uses.

Q

An architect can best discourage criminal activity in a street-level apartment lobby by applying which of the following design strategies?

A. separating the lobby and the street with a large expanse of glass.
B. changing the paving texture at the property line.
C. clearly marking the entrance with a “residents only” sign.
D. adding a bright light over the entrance door.

A

A - although all of these design features would help discourage criminal activity, the best approach would be to make activity inside the lobby visible from the street. This employs the principle of natural surveillance.

Changing the texture of the flooring between the sidewalk and the private property, using a sign, and adding a light are methods of territorial reinforcement, but they would not be as effective as opening the lobby to public view.

In regard to blast security, the space between a building and the outermost secured perimeter is called the

A. blast reduction zone
B. perimeter defense area
C. security setback
D. standoff distance

A

D - The standoff distance is the space between a building and the potential location of a blast threat. For blast protection, this distance should be maximized because blast energy decreases exponentially with increased distance between the source of the blast and the building.

Q

An architect is developing a site plan for a developed property with an existing building. The building is in good condition and was used for the same purpose as the client’s proposed use of the site. Which of the following four strategies would earn the greatest number of points within the Leadership in Energy and Environmental Design (LEED) 2009 for New Construction rating system?

A. Maintain at least 50% of the interior nonstructural elements.
B. Remove the building and recycle and/or salvage at least 50% of construction and demolition debris.
C. Maintain at least 95% of the existing walls, floors, and roof.
D. Reuse materials from the site that amount to 5%, by cost, of the total value of materials on the project.

A

C - If 95% or more of the existing building’s structure, exterior walls, and roof are reused, the LEED 2009 NC rating system awards three points, one point each for reaching levels of 55%, 75%, and 95% (MR Credits 1.1 through 1.3). Window assemblies and nonstructural roofing material are excluded from these calculations.

(Under the older LEED NC rating system v2.2, two points were awarded, for 75% and 95%)

In the LEED 2009 NC rating system, each of the other three strategies - maintaining 50% of the interior nonstructural elements (MR Credit 1.4), recycling and/or salvaging 50% of the debris (MR Credit 2.1), and reusing materials from the site worth 5% by cost, of the total value of materials (MR Credit 3.1) - would earn only 1 point.

Q

According to model codes, the minimum width of an office exit corridor serving an occupant load of 55 is

A. 36”
B. 42”
C. 44”
D. 48”

A

C - Model codes prescribe a minimum corridor width of 44”, with various exceptions. Corridors in residential occupancies or those serving an occupant load of less than 50 may be 36” wide. Other occupancies require wider corridors, but B occupancies (offices) require the 44” width.

Model codes also require that the minimum width of an exit corridor be calculated by multiplying the occupant load by a factor given in the codes, which varies depending on the occupancy, the interior area of the building, and whether the building is sprinklered. Both requirements must be checked, and the larger of the two should be used. If this calculation results in a number larger than other minimum requirements given in the code (such as for corridors), then the larger dimension must be used.

Q

The maximum allowable floor area of a building is primarily determined by the

A. city planning board
B. International Building Code (IBC)
C. Life Safety Code
D. Zoning Ordinance

A

D - A local city planning board may have requirements for building sizes, but the requirements are not a primary determinant. The IBC limits the allowable floor area of a building based on occupancy, building construction type, frontage, and whether the building is sprinklered, all of which may set a limit more or less than a zoning ordinance. For example, a zoning ordinance may set a maximum limit of 200,000 sq.ft., but using a type IIA construction with no frontage may limit the area to 150,000 sq.ft. The Life Safety Code also places restrictions on building area; however, like the IBC, it is not the primary determinant until occupancy and building type are determined. A zoning ordinance sets limits on the floor area ratio based on the lot size, setbacks, maximum height, and solar access, among other possible parameters. A combination of these factors will determine the maximum allowable floor area.

Q

An architect is designing a house in Georgia. She is determining how cross-ventilation can be maximized as a form of cooling. Which of the following should be considered for this project? Select 3

A. Locate opening ins rooms across from, but not directly opposite, each other.
B. Locate opening in rooms exactly across from each other.
C. Place larger openings on the leeward faces of the building.
D. Place larger openings on the windward faces of the building.
E. Place inlets at higher pressure zones and outlets at lower pressure zones.
F. Place outlets at higher pressure zones and inlets at lower pressure zones.

A

A, C, E - It is generally not the best to place openings exactly across from each other, even though it does provide ventilation, it can cause parts of the room to be far better cooled and ventilated than others. Placing inlets low and outlets high can cool the space more effectively because the strategy is able to leverage natural convection.

Q

Which of the following domestic water heating systems would yield the lowest operating costs for a duplex residential unit?

A. active closed-loop solar
B. direct-fired storage tank
C. ground-source heat pump
D. tankless instantaneous

A

A - a solar water heating system would have the lowest long-term operating cost because no fuel costs would be involved.

A standard direct-fired system would require purchasing gas, oil, or some other type of fuel to heat the water. A ground-source heat pump would not be able to supply water hot enough for domestic use and is inappropriate for this application; ground-source heat pumps are used for heating the home, not water. A tankless instantaneous unit would incur ongoing expenses due to its use of electricity and is not appropriate for general household domestic hot water generation.

42
Q

Which of these is the most important concern in relation to a private water supply?

B. humidity
C. motors and equipment
D. air movement
E. people
F. fluorescent lighting
A

A, C, E, F - Humidity and air movement do not affect heat gain. Although the effect of motors and equipment, people, and lighting may vary in different types of occupancies, they all produce heat.

Q

A building in a temperate climate will have some areas that require cooling and others that require heating at the same time. To minimize energy use, the best devices to employ are

A. energy recovery ventilators
B. heat pumps
C. recuperative fuel economizers
D. water-loop heat pumps

A

D - Water-loop heat pumps are a continuous flow of temperate water to extract heat from areas that need to be cooled and add heat to other areas requiring heating using very little, if any, additional energy input.

Energy recovery ventilators work best in climates where the difference between indoor and outdoor air temperatures is high. Heat pipes are not appropriate for this use because they would simply pre-warm cool outdoor air. A recuperative fuel economizer is another type of system that simply uses hot exhaust gas to preheat incoming air or water. This type of equipment would save energy by increasing the efficiency of the heating plant but would not be as effective as the water-loop heat pump system.

46
Q

A seven-story office building is to have a variable air volume system. The building will have 105,000 sq ft of net space and an estimated 126,000 sq ft of gross area. About how much space should be the minimum area allowed for heating, ventilating, and air conditioning (HVAC) systems?

A. 2500 sq ft
B. 3800 sq ft
C. 6300 sq ft
D. 7600 sq ft

A

D - For most midsize buildings, an all-air or air-water system needs about 3-9% of the gross area for HVAC system mechanical space. Office buildings fall somewhere near the midpoint of the range, so use 6% for this question. 6% of the estimated 126,000 sq ft gross area is 7560 sq ft. This is rounded up to 7600 sq ft, so option D is correct as a minimum estimated area.

47
Q

Air barriers are designed to stop infiltration and exfiltration caused by which of the following? Select 4.

A. stack effect
B. vapor pressure
C. HVAC fan pressure
D. wind pressure
E. temperature differentials
F. exhaust vents
A

A, C, D, F - Wind pressure, stack pressure, and HVAC fan pressure all can influence infiltration and exfiltration rates. Vapor pressure does not cause air movement; rather, vapor pressure is a movement of moisture. Temperature differentials have little effect on infiltration or exfiltration.

48
Q

Which of the following are typical rules to keep in mind for surface water management? Select 2.

A. Land adjacent to buildings should slope at least 2%
B. Grass lawns should slope no more than 20%
C. Paved parking areas should slope between 4% - 10%
D. Slopes greater than 50% should be avoided.

A

A, D - Land adjacent to buildings should slope at least 2% to avoid water getting into the building. Slopes greater than 50% should be avoided as they can lead to erosion.

49
Q

When orienting a building on a site, an architect should account for which of the following climatic conditions? Select 3.

A. Solar orientation
B. Average rainfall
C. Natural features
D. Snow loads
E. Prevailing wind direction
A

B, D, E - When orienting a building on site, an architect should account for average rainfall, snow loads, and prevailing wind direction. All of which are representative of climactic conditions. Solar orientation and natural features are site conditions.

50
Q

To be considered dry lumber, moisture content in wood cannot exceed which of the following?

A. 19%
B. 20%
C. 24%
D. 25%

A

A - to be considered dry lumber, the moisture content of wood cannot exceed 19%

51
Q

Which of the following is the decibel level of background noise?

A. 30db
B. 35db
C. 40db
D. 75db

A

B - Background noise is typically at a decibel level of 35db. Transmitted noise occurs at 30db.

52
Q

An architect is developing the overall building layout on a specific site. Which of the following are most likely to impact her plan. Select 3.

A. Zoning
B. International Building Code
C. Easements
D. International Fire Code
E. Homeowners Association
A

A, C, E - Zoning ordinances will regulate both the types of activity that may occur on a site and the location and mass of the building or buildings. Easements set the minimum required distances from the structure to the property lines. Most HOAs have additional rules regarding building heights, setbacks, and potentially even building layouts (i.e., garage must not be visible from the front of the house).

53
Q

An Architect has a client return after a year of living in their home with a few complaints. The gas fireplace is not working well, the doors and windows can be difficult to open, and odors tend to linger. The Architect has realized the house is pressurized. Which of the following should be done to remedy the situation?

A. Fix each individual problem
B. Replace the return air grilles
C. Repair the mechanical system to rebalance the pressure
D. Install fresh air intakes
E. Increase the crawl space ventilation
A

D - all issues are due to having a well constructed air-tight building. The goal is to keep the air tight construction while bringing in fresh air.

54
Q

A power distribution system is to be specified for an open office area. Which of the following is the most flexible and economical alternatives?

A. access floor system
B. underfloor raceway system
C. cellular metal floor raceways
D. ceiling raceway system with pole raceways

A

D - Any of the options would allow flexibility, but the ceiling raceway system with pole raceways would be the least expensive.

An access floor system consists of individual panels, typically 24” square, supported by adjustable pedestals above the structural floor. These systems provide unlimited flexibility for routing power, communications, and air supply, but are expensive and not justified unless a great deal of cabling is involved or future changes will be extensive (such as in a computer room). An underfloor raceway system consists of a series of parallel rectangular metal raceways laid on the structural slab and covered with concrete. A cellular metal floor raceway is similar in concept, but s part of the structure. Raceways are similar to standard metal decking and serve as conduits for power and communication cabling. In both underfloor and cellular metal floor systems, the raceways are tapped when power and communication outlets are required.

55
Q

High voltages are used in commercial buildings because

A. conductors and conduit can be smaller
B. a wider variety of loads can be accommodated
C. commercial buildings require more power
D. transformers can step down the voltages to whatever is needed

A

A - As voltages increase, current may be decreased and the system will still provide the same amount of power. Lower currents require smaller conductors. For large commercial buildings, smaller conductors translate to less expense in conductors and conduit, as well as easier installation of smaller wires.

56
Q

Which would be the best location for a transformer for a large school building?

A. on the power pole serving the building
B. in a separate room near the exterior wall
C. outside, on a transformer pad close to the main switchgear
D. in a protective shed where power from the utility company enters the property

A

B - A transformer vault near the exterior wall would be the best choice for protection, ventilation, and ease of installation and removal. A large school building would require high voltage service from the utility company and step-down transformers provided by the owner. This type of transformer could not be installed on a pole. Although the transformer could be placed on a pad outside the building, this would leave it exposed to possible vandalism and might present a danger to the students.

57
Q

Which of the following types of lamps provides the best color rendition of skin tones?

A. cool-white fluorescent
B. incandescent
C. mercury vapor
D. metal halide

A

B - an incandescent lamp has a high color rendering index (CRI) and low color temperature, with a predominance of light in the red range. These characteristics give a complimentary rendering to skin tones.

A cool white fluorescent lamp has more blue and green light in its spectral distribution and makes skin tones appear more gray and washed out. Both mercury vapor and metal halide lamps have poor color rendering indexes and are not appropriate for lighting areas where skin tone rendition is important.

58
Q

The zonal cavity method of calculating average illumination on the work surface for a given number of luminaires depends on which of the following variables? Select 4

A. angle of light
B. dirt accumulation
C. efficacy of the lamp
D. lumens per lamp
E. room size
F. wall reflectance
A

B, D, E, F - The zonal cavity method is used to calculate the total number of luminaires required to achieve the desired average illumination on the work surface, which is assumed to be 30 in above the floor. The variables considered in the calculation include the level of illumination desired, the area of the room, the number of lamps in each luminaire, the lumen output of each lamp, the coefficient of utilization, the light loss factor, wall reflectance, and the gradual loss of light due to dirt accumulation.

The coefficient of utilization (CU) is a measure of the efficiency of a particular lumniaire in outputting light and is based on the design of the luminaire itself, the reflectance of the room, and the size of the room. The light loss factor represents a degradation of ideal light output due to aging of the lamp and gradual dirt accumulation on the lamp.

59
Q

Problems with veiling reflections in a general-purpose workroom could best be reduced by

A. substituting ambient light for direct light fixtures
B. repositioning the light fixtures
C. reducing the brightness of the light fixtures
D. changing the type of lamps

A

A - A veiling reflection is glare caused when the image of a light source is reflected from a viewing surface into the eye. The best way to reduce it is to provide general background illumination (ambient lighting) so the light sources are not concentrate in the area of the lamp.

Repositioning the luminaires (or the task) can reduce veiling reflections, but only when the task is in a specific location in relation to the light source. In a general-purpose workroom this would not be feasible. Reducing the brightness of the light source would help, but would also reduce the illumination provided for the task. Changing the type of lamps would have little effect on reflected glare.

60
Q

Variables that must be considered when designing for daylighting include which of the following? Select 4.

A. longitude of the site
B. glass transmittance
C. height of the head of the glass
D. height of space above ground level
E. outdoor surface reflection
F. room surface reflection
A

B, C, E, F - The longitude of the site is not a factor in daylight design. The latitude of the site might have a minor influence on how a daylighting design is implemented, but this is not a critical variable. The height of the space above the ground level does not have a direct influence on daylighting except that it may affect tree obstructions and outdoor surface reflection.

Variables that affect daylighting include the brightness of the sky (which is affected by solar altitude, cloud conditions, and time of day), the area of the glass, the height of the head of the glass, the transmittance of the glass, the reflectance of surfaces within the rooms and nearby outdoor surfaces, and obstructions such as overhangs and trees.

61
Q

Which of the following can increase a heat pump’s efficiency?

A. Connect the heat pump to a natural gas generator.
B. Connect the heat pump to an electrical resistance heating source.
C. Connect the heat pump to a refrigerant.
D. Connect the heat pump to a solar energy system.

A

D - To increase a heat pump’s efficiency, connect the heat pump to a solar energy system, which will provide heat during a moderate range of temperatures to reduce strain on the system.

62
Q

Roof and ceiling assembly design can reduce heat transmission by which of the following? Select all that apply.

A. Using light-colored roof materials to reflect heat
B. Using steeply pitched roofs on the windward side
C. Using louvered overhangs
D. Decreasing the thermal mass
E. Sealing attic spaces from air leakage

A

A, B, C - Increasing the thermal mass would mitigate heat transmission, and ventilating attic spaces would reduce transmission.

63
Q

Which of the following has the least embodied energy?

A. Copper
B. Lead
C. Stainless steel
D. Corrugated galvanized iron

A

D - Corrugated galvanized iron requires 40,330 btu per lb.
Copper requires 265,140 btu per lb.
Stainless steel requires 138,300 btu per lb.
Lead requires 105,620 btu per lb.

64
Q

When conducting a life cycle assessment of the environmental impact of a material, which of the following would be components of that process? select 4

A. Transportation analysis
B. Goal definition
C. Inventory analysis
D. Impact assessment
E. Recycling method
F. Improvement analysis
A

B, C, D, F - An LCA would include goal definition, inventory analysis, impact assessment, and improvement analysis. It would not include a transportation analysis or recommend a recycling method.

65
Q

An Architect is trying to select a boiler for a small office. There is not a lot of space in the basement for the boiler, and they do not have a maintenance program. Which of the following boiler systems should be selected?

A. Cast iron
B. Firetube
C. Vertical firetube
D. Electric

A

C - The vertical firetube system needs very little space and does not require a lot of maintenance. Cast iron and electric systems require higher levels of maintenance. The firetube system requires a medium to large amount of space.

66
Q

Which of the following is typically used to determine the maximum load for a water supply system?

A. Probable demand
B. Standard demand
C. Regular demand
D. Plumbing demand

A

A - Probable demand is the term for determining the maximum load for a water supply system. This takes into consideration that most plumbing systems are not used all at once for an extended period of time in a building.

67
Q

When selecting the size of a pipe, which of the following should be kept in mind? Select 3.

A. Flow rate
B. Material
C. Pressure
D. Velocity

A

A, C, D - The size of the pipe needed would be dependent on the flow rate, pressure, and velocity, all of which are factors in how large or small a pipe should be used. The material the pipe is made of is of less importance.

68
Q

An Architect is designing a two story wood framed building that needs a clear span of 35 feet. Which for the following systems would work to support the second floor? Select all that apply.

A. Laminated beams
B. Trussed rafters
C. Box beams
D. Open-web joists
E. planking
A

A, C, D - span rating shows laminated beams, box beams, and open-web joists can all span 35 feet. Trussed rafters is incorrect because, even though it can span 35 feet, it would not be good for supporting a second floor.

69
Q

A three-story building was initially designed with a shallow foundation system. The client has partnered with another company on the project and would now like to add two additional stories. The foundation may no longer be able to carry the load. Which of the following are options the architect should consider to accommodate the additional stories? Select 2.

A. Reduce the height by broadening the building.
B. Change the foundation system to wall footings to better distribute the load.
C. Utilize a floating foundation system.
D. Increase then umber of columns in the building and decrease their spacing.

A

A, D - Reducing the height by broadening the building will allow the architect to keep the same shallow foundation system, the loading on the foundation will remain the same, and the footprint of the building and foundation just grows. Increasing the number of columns and decreasing the spacing can allow the foundation to accommodate more load. Changing to a different shallow foundation footing system will not help the situation. A floating foundation is used when the bearing capacity of soils is low.

70
Q

A project brief calls for a new office headquarters building with flexible workspace configurations in a cold climate. Which of the following options best responds to the project’s constraints?

A. A compact building with a moderately high floor to floor height.
B. A long, rectangular building form with windows on the two long sides and a minimum floor to floor height.
C. A compact building with a covered atrium light well through the center of the building and a minimum floor to floor height.
D. A compact building with a low floor to floor height.

A

A - A compact building form is most appropriate for cold climates. The higher FTF height provides daylighting for flexible workspace layouts. The wrong answers have forms for temperate climates, and the atrium does not support a flexible program.

71
Q

A project located in southwest Montana would be best-suited for which alternative energy system?

A. Hydropower
B. Wind turbine
C. Natural gas
D. Geothermal energy

A

D - Southwest Montana is where the highly active geysers/volcano of Yellowstone National Park are located. This area is well-suited for geothermal energy.

72
Q

Which of the following aspects of a lighting system will indicate the color temperature of the lamp (absolute temperature in degrees Kelvin)?

A. CRI
B. LPW
C. CCT
D. CIE

A

C - Correlated Color Temperature (CCT) indicates the color temperature of a lamp in degrees Kelvin. The Color Rendering Index (CRI) is not measured in Kelvin and indicates the color shift in the objects illuminated. Lumens Per Watt (LPW) indicates the efficacy of a lamp. The International Commission on Illumination (CIE) known from its French title, the Commission International de l’ Eclairage - publishes standards guiding the science and art of light and lighting, color and vision, photobiology and image technology.

73
Q

The bioclimatic chart measures which two variables to determine the comfort zone?

A. Daily high temperature and daily low temperature
B. Relative humidity and daily high temperature
C. Average high temperature and average low temperature
D. Temperature and relative humidity

A

D - Temperature and relative humidity

74
Q

Which of the following design elements can reduce crime? Select 2

A. Large windows
B. High walls
C. Window coverings
D. Low walls

A

A, D - Large windows are design elements that can reduce crime. Large windows provide transparency, and low walls can form an implied barrier between public and private or semiprivate space. High walls and window coverings reduce the ability to see activity happening in the area.

75
Q

An area of refuge must have which of the following? Select 3.

A. A platform lift
B. A two-way communication device
C. A steady supply of outside air
D. Emergency lighting
E. Access to an elevator
A

B, C, D - Two-way communication, a steady supply of outside air, and emergency lighting are all components required in an area of refuge.

76
Q

To reduce the risk of condensation within the wall structure, where would the best location for the vapor barrier be installed in a new house in Ohio?

A. Between the insulated studs and the exterior insulation
B. The inside face of the building
C. Outside of the exterior insulation behind the siding
D. Inside of the studs behind the sheetrock

A

A - By insulating both sides of the vapor barrier, you reduce the drastic air temperature differentiation that is the cause of condensation

77
Q

Can a 23,000 sf storage facility relocate to a 1/4-acre site with an allowable FAR of 2.0?

A. No; the site would be too large.
B. No; the site would be too small.
C. Yes; the site would be exactly the right size.
D. Yes; the site would be large enough.

A

B - 1 acre = 43,560 sf; 1/4 acre = 10, 890 sf; 1/4 acre at 2.0 FAR = 21,780 sf.

Smaller than the sf needed for the storage facility.

78
Q

A public elementary school is looking to install new benches as part of their playground remodel. Which of the following ideas would have a low environmental impact based on their embodied energy, maintenance, and life cycle?

A. Recycled plastic benches
B. Brick walkways
C. Wood chip play area fill
D. Gravel walkways
E. Recycled tire play area fill
A

A, D, E - Recycled plastic benches, gravel walkways, and recycled tire play area fill, all have low embodied energy and are long-lasting materials that do not have negative side effects in an outdoor environment.

79
Q

The Architect is designing a small dental office where they need to bring in outside air to supply the building. The exterior dry bulb temperature is 90 degrees F, and the relative humidity is 54%. The client wants the inside dry bulb temperature to be 64 degrees F and hte relative humidity to be 4%. WHic hfo the following methods are required to transition the exterior conditions to match the interior conditions? Select all that apply.

A. Cooling and dehumidification
B. Reheating sensible only
C. Evaporative cooling only
D. Heating and humidifiying
E. Moisture but no heat
A

A, B - To reduce the relative humidity you need to cool and dehumidify the air. Once the air is at the right level of relative humidity, the air needs to be heated to the necessary temperature.

80
Q

A hospital would most likely use which of the following heating systems? Select 2

A. induction system
B. electric system
C. fan coil system
D. direct expansion system

A

A, C - Of the choices, a hospital would likely use an induction or fan coil system because each of these allow for a complete exhaust to the outside, which is important in a hospital setting.

81
Q

Which of the following would an architect be most concerned about when designing the lighting for an office space with computer workstations and standard desks? Select 3

A. color rendering index
B. visual comfort probability
C. task/surroundings brightness ratio
D. veiling reflection
E. reflected glare
F. lighting uniformity
A

C, D, E - In an office space where computer monitors and standard office tasks are present, the architect should be concerned with two results of glare. Veiling reflection would be of concern for standard office tasks such as writing and reading, where as reflected glare would be critical in using the monitors. The brightness ratios between the tasks and their surroundings are important, especially when employees spend hours in front of a computer monitor. The color rendering index, visual comfort probability, and lighting uniformity are less important.

82
Q

Why would high-pressure sodium lamps be favored over low-pressure sodium lamps in a storage warehouse?

A. They are less expensive
B. They have a longer lamp life
C. They can operate at higher, more efficient voltages
D. They have better color-rendering properties

A

D - Low-pressure sodium lamps produce a monochromatic yellow light that would not be appropriate in a storage warehouse where people may have to discriminate between colors.

83
Q

A material supplier states that adding a certain product to a wall assembly in a critical acoustical situation will increase the noise reduction (STC rating) between two spaces by 3 dB. What is the most appropriate response?

A. Determine the additional cost and then decide whether or not to use the product.
B. Thank the supplier for stopping by but explain that the architectural firm probably will not be using the product because the amount of noise reduction does not make it worth the effort of cost.
C. Specify the product as long as it does not affect the design or construction cost by more than 5%.
D. Inquire whether some modification can be made to the product to increase its rating to 6 dB and say that then the architectural firm might consider it.

A

B - Because a change in intensity of 3dB is considered “just perceptible,” it would probably be better not to use the material regardless of how low the added cost was. Trying to modify the material to 6dB would also probably not be worth the trouble. TO achieve an STC rating 6dB higher, it would be better to look at another type of construction assembly instead of trying to make do with a modified material. Option (D) could be correct if the material was such that doubling it rather than modifying it would result in a 6dB increase.

84
Q

A geared traction elevator would be most appropriate for a(n)

A. 5-story medical office building
B. 16-story office building
C. 4-story department store
D. 8-story apartment building

A

C - Geared traction elevators can be designed to serve a wide variety of slower speeds and high capacities, so they are ideal for low-rise buildings with heavy loads, such as department stores. A geared traction elevator could be sued for a small medical office building, but a higher speed would offer better service. A 16-story office building would need a high-speed, moderate-capacity elevator, so a geared traction type would be inappropriate. An apartment building would require a low capacity but higher speeds.

85
Q

What is the optimal location for an elevator machine room?

A. beside the elevator on the lowest level of the building
B. adjacent to the electrical room
C. above the hoistway
D. adjacent to the mechanical room.

A

C - Ideally, elevator mechanical rooms should be placed above the hoistway. They must be at least as wide as the elevator shaft and generally need to be more than 12 ft deeper than the hoistway, but the exact size of the space should be calculated considering the type of elevator specified, the sizes of all the equipment to be housed in the space, and the required servicing clearances.

86
Q

A client who has recently moved from New York to southern California has hired an architect to design a new house in the colonial revival style, which is similar to a former home. The architect should recognize that this building configuration request may be influenced by

A. cultural attitudes
B. status seeking
C. symbolism
D. regionalism

A

C - The client’s cultural upbringing is not known, so cultural attitudes cannot fully account for the client’s style preference. The client, as well as the architect, would probably see the cultural setting of California as very different from New York. Building a house, even a very large mansion, probably would not convey an image of status in southern California. It is more likely that if the client wanted status, the architect should design a large, unique house in a contemporary style. Regionalism is not a factor because the architectural styles of contemporary southern California are typically quite different from the northeast United States. Such a request is an example of how a certain style of building symbolizes what a home should look like. so the factor most likely driving the client’s request is symbolism.

87
Q

Which of the following factors accounts for the highest cost of a lighting system over time?

A. lamps
B. luminaires
C. installation
D. operation

A

D - Over the life cycle of a lighting system, the continuing operating cost for electricity is the single largest expense. For nonresidential applications, maintenance (i.e., the replacement of the lamps and cleaning of luminaires) is the second greatest expense.

88
Q

Which of the following are true about life-cycle cost analysis (LCCA)? Select 4

A. Higher up-front costs often lead to lower operational costs.
B. Costs presented in the analysis are the only factors that should be considered when making a decision about a material or system.
C. It is economical to complete a LCCA if two items have similar installation costs but differing operational costs or projected lifespans
D. LCCA evaluates all cots based upon their present value.
E. A LCCA is similar to a life-cycle assessment (LCA).
F. Salvage fees may be included in a LCCA.

A

A, C, D, F - LCCA allows designers and owners to evaluate the total cost of a product or system over its useful life. This facilitates an objective comparison between two or more options based upon a number of factors, including their initial purchase price, long-term maintenance costs, replacement costs over time, and any portion of the investment that may be recouped through salvage fees. Of course, this analysis is not the only factor that should be considered when making decisions about what to include in a building’s design, but it does permit a comprehensive look at the total cost to the owner that decision will incur. An item that looks like a bargain in terms of its present-day purchase price may have steep operational costs or a short lifespan, requiring replacement in just a few years. Life-cycle costing takes all of these factors into consideration and converts all of the costs to present-day values so that they can be compared effectively. An LCA is a method of evaluating the environmental impact of using a material or product, and it is not the same as an LCCA.

89
Q

During design development for a small corporate headquarters building, the client informs the architect that, due to poor sales in the previous quarter, the budget for the project must be reduced. Which of the following actions should the architect ignore in order to reduce initial construction costs?

A. reducing the number of pieces in the the details.
B. eliminating high maintenance finishes
C. suggesting changes that would make custom finishes closer to industry standards.
D. reducing the number of different details involved in the project.

A

B - Using industry-standard details, reducing the number of components in the construction assembly, and reducing the number of unique details all would help reduce construction costs.

Although life-cycle costs are a consideration in a corporate headquarters (presumably owner-occupied and maintained), the problem refers to initial construction costs.

90
Q

Which of the following strategies would be employed in a community adopting the principles of defensible space? Select 4.

A. gated streets
B. strict enforcement of code regulations
C. loan programs for first-time homebuyers
D. concentration of all housing in one area
E. specification of vandal-resistant materials
F. clear distinctions between public and private spaces.

A

A, B, C, F - Defensible space is a theory that is based on the principles developed by Oscar Newman. The case studies cited in his book describe some of the techniques used to help create a sense of pride of ownership in a neighborhood.

In Dayton, Ohio, mini-neighborhoods were created through the use of gated streets. However, as Newman pointed out, gated streets alone are insufficient; successfully implementing the principles of defensible space requires stricter enforcement of building codes (including attaching criminal charges for noncompliance), help for new homeowners to finance and maintain their properties, and community programs designed to facilitate interaction among neighbors.

At Clason Point in New York City, New York, Newman describes a row house project where the aesthetics of the community contributed to its demise: “temporary” concrete block buildings outfitted with vandal-resistant materials and separated by open spaces that were perceived as dangerous. Newman and the planners introduced barriers such as curbs and fences to define private and semiprivate spaces, limited and widened pedestrian walkways to allow for better visibility and supervision, and refaced existing structures with more “residential” materials that the residents helped to choose. They also allocated a portion of the common grounds to each family and encouraged them to grow grass in order to take ownership of the space outside their homes.

In Yonkers, New York, implementing defensible space principles involved scattering factory-built row houses on a number of sites throughout the city, rather than clustering the low-income residents in a high-rise.
