NEW QUESTION # 15
A facility manager cleaning highly reflective paving material is
- A. lowering the Solar Reflectance Index (SRI)
- B. increasing the heat island effect
- C. unnecessarily wasting water
- D. reducing the heat island effect
Answer: D
Explanation:
Explanation
The heat island effect is the phenomenon of urban areas having higher air temperatures than surrounding rural areas due to the absorption and emission of heat by human-made surfaces, such as buildings, roads, and pavements. The heat island effect can have negative impacts on theenvironment, human health, and energy consumption. One of the strategies to reduce the heat island effect is to use highly reflective paving materials that have a high solar reflectance index (SRI), which measures the ability of a surface to reflect solar radiation and stay cool. However, over time, the paving materials can accumulate dirt and dust, which can lower their reflectance and increase their heat absorption. Therefore, a facility manager cleaning highly reflective paving material is reducing the heat island effect by restoring the reflectance and cooling potential of the surface12.

NEW QUESTION # 25
A Healthcare Project is constructing a new building adjacent to an existing LEED Certified hospital facility.
The new building's location is on the same hospital campus as the certified facility. The entire hospital campus was analyzed with an Environmental Site Assessment (ESA) as part of the certified facility's project scope. The new building project needs to complete a new Phase I ESA if
- A. the local equivalent standard is more stringent than ASTM E1527-05
- B. the Phase II ESA uncovers suspected contamination
- C. contamination was identified by the certified facility
- D. the certified facility's Phase I ESA is older than 180 days
Answer: A
Explanation:
the local equivalent standard is more stringent than ASTM E1527-05
According to the LEED v4 Reference Guide for Building Design and Construction, a Phase I ESA is required for all projects, except for those located on previously developed land that has not been used for industrial, commercial, or agricultural purposes. The Phase I ESA must follow the ASTM E1527-05 standard or a local equivalent. However, if the local equivalent is more stringent than the ASTM standard, then the project must comply with the local equivalent. Therefore, if the new building project is located in a jurisdiction that has a more rigorous standard for Phase I ESA than ASTM E1527-05, then it must complete a new Phase I ESA, regardless of the previous ESA done for the certified facility.
NEW QUESTION # 26
Which of the following would be most useful to a school project that is attempting to pursue Water Efficiency Credit, Indoor Water Use Reduction?
- A. A standard garbage disposal
- B. An open-loop HVAC system that discharges potable cooling water to a nearby lake
- C. Electronic submeter at the domestic water supply pipe to the building
- D. Commercial dishwasher that is ENERGY STAR labeled or performance equivalent
Answer: D
Explanation:
The Water Efficiency Credit, Indoor Water Use Reduction aims to reduce indoor water consumption by installing water-efficient fixtures and fittings, such as faucets, showerheads, toilets, and urinals1. A commercial dishwasher that is ENERGY STAR labeled or performance equivalent would help reduce the water use for dishwashing, which is one of the process water uses included in the credit calculation2. A standard garbage disposal would not reduce water use, but rather increase it. An electronic submeter at the domestic water supply pipe to the building would help measure and monitor water use, but not directly reduce it. An open-loop HVAC system that discharges potable cooling water to a nearby lake would waste a lot of water and potentially harm the environment.
