質問 # 55
Which system is eligible for the Energy and Atmosphere Credit, Renewable Energy Production?
- A. Ground-source heat pumps
- B. Tidal-based electrical production
- C. Passive solar and daylighting strategies
- D. Municipal solid waste combustion
正解：B
解説：
Explanation
Tidal-based electrical production is eligible for the Energy and Atmosphere Credit, Renewable Energy Production. This credit rewards projects that use renewable energy systems to offset building energy cost.According to the LEED v4 BD+C Reference Guide, renewable energy systems are defined as "those that use resources that are naturally replenished within a 100-year or shorter cycle and that are greenhouse gas neutral on an annual basis"1. Tidal-based electrical production meets this definition, as it uses the kinetic energy of the tides to generate electricity without emitting greenhouse gases. The other options are not eligible for this credit, as ground-source heat pumps are not considered renewable energy systems, municipal solid waste combustion is not greenhouse gas neutral, and passive solar and daylighting strategies do not offset building energy cost.References: LEED v4 BD+C Reference Guide, Energy and Atmosphere Category, EAc Renewable Energy Production, page 572.

The Solar Reflectance Index (SRI) includes the measure of a material's
- A. ability to reflect solar radiation
- B. color (shade of gray)
- C. ability to absorb solar radiation
- D. ability to reflect thermal radiation
正解：A
解説：
The Solar Reflectance Index (SRI) is a measure of the roof's ability to reject solar heat, as shown by a small temperature rise. It is defined so that a standard black (reflectance 0.05, emittance 0.90) is 0 and a standard white (reflectance 0.80, emittance 0.90) is 100. SRI is calculated using the roof surface's Solar Reflectance (SR) and Thermal Emittance (TE). SR is the fraction of solar energy that is reflected by the roof, and TE is the relative ability of the roof surface to radiate heat. Therefore, SRI includes the measure of a material's ability to reflect solar radiation, but not its ability to absorb or emit thermal radiation.

Which strategy should be employed to improve daylighting when designing a new building?
- A. Increase the number of skylights
- B. Increase the height of interior partitions
- C. Decrease the number of exterior light shelves
- D. Increase the building depth
正解：A
解説：
. Increase the number of skylights
Skylights are openings in the roof or ceiling that allow natural light to enter the building. They can improve daylighting by providing more uniform and diffuse illumination, reducing the need for artificial lighting, and enhancing the visual comfort and well-being of occupants. Skylights can also reduce cooling loads by minimizing solar heat gain through the roof. However, skylights must be designed carefully to avoid glare, overheating, and heat loss issues.
