LEED-AP-BD-C Exam Questions and Answers

QUESTION: 51

For Energy and Atmosphere Credit, Advanced Energy Metering, what is the minimum amount of time that the metering system should store data?

6 months
12 months
24 months
36 months

Answer(s): D

Explanation:

For Energy and Atmosphere Credit, Advanced Energy Metering, the minimum amount of time that the metering system should store data is 36 months. This is to ensure that the data can be used for long-term analysis and verification of energy performance. The credit also requires that the metering system be capable of transmitting data to a remote location and reporting energy use at least hourly.

QUESTION: 52

Which energy efficient lamp type is free from mercury?

Compact Fluorescent
High Pressure Sodium
Light Emitting Diode
T-8 Fluorescent

Answer(s): C

Explanation:

Light Emitting Diode (LED) is an energy efficient lamp type that is free from mercury. Mercury is a toxic metal that can pose health and environmental risks when released from broken or discarded lamps. LED lamps do not contain mercury or other hazardous substances, and they also have longer lifespans and lower energy consumption than other lamp types.

QUESTION: 53

Which of the following will contribute to reducing the heat island effect?

Artificial turf grass
Intensive vegetated roof
Steep sloped roof with initial SRI of 35
Low sloped roof with initial Solar Reflectance Index (SRI) of 64

Answer(s): B

Explanation:

An intensive vegetated roof is a roof that has a thick layer of soil and plants that provide shade, evapotranspiration, and stormwater management. It can reduce the heat island effect by lowering the surface and air temperature of the roof and the surrounding area. Artificial turf grass does not reduce the heat island effect because it is not a living plant and does not provide cooling benefits. A steep sloped roof with initial SRI of 35 does not meet the minimum requirement of 39 for Option 1 or 32 for Option 2 of the Heat Island Reduction credit. A low sloped roof with initial SRI of 64 exceeds the minimum requirement of 82 for Option 1 or 64 for Option 2, but it is not the best option among the choices because it only reflects solar radiation and does not provide other benefits such as shading, evapotranspiration, and stormwater management.

QUESTION: 54

In the calculations for Water Efficiency Credit, Outdoor Water Use Reduction, food gardens

must be calculated using at least 20% from an alternative water source
must be calculated using 100% potable water
may be included or excluded from the calculations
may be calculated using a standard 20% reduction from baseline

Answer(s): C

Explanation:

Food gardens may be included or excluded from the calculations for Water Efficiency Credit, Outdoor Water Use Reduction, as per the project team's discretion. If included, food gardens must be calculated using 100% potable water. If excluded, food gardens must be irrigated with 100% captured rainwater, recycled graywater, or water treated and conveyed by a public agency specifically for nonpotable uses.

QUESTION: 55

The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will

be advertised as LEED compliant
be both water efficient and high performing
comply with mandatory federal government regulations
comply with all international plumbing system requirements

Answer(s): B

Explanation:

The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will be both water efficient and high performing. The WaterSense label is a voluntary program by the U.S. Environmental Protection Agency (EPA) that identifies and promotes water-efficient products that meet EPA's specifications for water efficiency and performance. The label applies to tank-type toilets, water-using urinals, private lavatory faucets, and showerheads. For projects outside the U.S., local equivalents may be used if they meet the same criteria as WaterSense or are listed on the USGBC website. The label does not imply that the fixtures are LEED compliant, comply with mandatory federal government regulations, or comply with all international plumbing system requirements.
