質問 # 34
Relating to water efficiency in LEED. gallons per minute or liters per minute refers to the amount of
- A. water used by flush fixtures
- B. stormwater runoff
- C. water used by flow fixtures
- D. captured rainwater
正解：C
解説：
Explanation
Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED. Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per minute (L/min), which indicates how much water flows through them in a given time period. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to "use low-flow faucets and showerheads (maximum 2.5 gpm at 80 psi)" [1, p. 14].

質問 # 36
Which of the following Is a measure of energy use intensity?
- A. Energy consumed per unit of floor space
- B. Daylighting and views
- C. Systems with ENERGY STAR" requirements
- D. The amount of electricity a wind turbine can produce
正解：A
解説：
Energy use intensity (EUI) is a measure of energy use per unit of floor space. It is calculated by dividing the total energy consumed by the building in one year (measured in kilowatt-hours or kilo-British Thermal Units) by the total gross floor area of the building (measured in square feet or square meters). EUI is a useful metric for comparing the energy performance of different buildings or benchmarking against national averages. EUI can vary depending on building type, climate, occupancy, and other factors. Generally, a lower EUI indicates better energy efficiency and lower environmental impact.

What is the best way to prevent a building's indoor pollutant(s)?
- A. Remove any pollutants that enter the building
- B. Eliminate or control pollutants at the source
- C. Monitor carbon dioxide
- D. Test for radon
正解：B
解説：
The best way to prevent a building's indoor pollutant(s) is to eliminate or control pollutants at the source. Indoor pollutants are substances or particles that can adversely affect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Indoor pollutants can originate from various sources, such as building materials, furnishings, cleaning products, combustion appliances, outdoor air, or occupant activities. Eliminating or controlling pollutants at the source can prevent them from entering or spreading in the indoor environment, which can reduce the exposure and risk for the occupants. Some examples of source control strategies are: using low-emitting materials, installing local exhaust ventilation, sealing combustion appliances, implementing green cleaning practices, and prohibiting smoking13.

- A. 10 additional points
- B. 15 additional points
- C. 30 additional points
- D. 20 additional points
正解：D
解説：
Explanation
LEED certification is awarded based on the number of points a project earns across several categories of green building performance. The range of points required to achieve LEED Silver is 50-59, out of a possible 110 points. The other levels of LEED certification are: Certified (40-49 points), Gold (60-79 points), and Platinum (80 or more points)12. Therefore, if a project initially has 34 credit points, it would need 20 additional points to reach the minimum threshold for LEED Silver.

- A. Designating parking spaces closest to the building for exclusive use by carpooling vehicles
- B. Utilizing an existing community nature path connecting the building to surrounding buildings
- C. Providing shuttle access between the project site and a local transit center
- D. Placing a low speed limit in the parking lot around the building
正解：B
解説：
Utilizing an existing community nature path connecting the building to surrounding buildings is an action that promotes pedestrian access to a project site. Pedestrian access is the ability of people to walk to and from a project site safely and comfortably. A community nature path is a type of pedestrian infrastructure that provides a pleasant and scenic route for walking, as well as environmental benefits such as habitat creation, stormwater management, and heat island reduction. The other options are not actions that promote pedestrian access to a project site. Placing a low speed limit in the parking lot around the building is an action that enhances pedestrian safety within the project site, but does not improve pedestrian access to the project site. Providing shuttle access between the project site and a local transit center is an action that encourages alternative transportation, but does not promote pedestrian access to the project site. Designating parking spaces closest to the building for exclusive use by carpooling vehicles is an action that reduces vehicle trips and emissions, but does not promote pedestrian access to the project site. Reference: LEED Green Associate Candidate Handbook, page 30; USGBC, [Location & Transportation], page 3.
