NEW QUESTION # 20
Which is a benefit of earning Regional Priority credits?
- A. The context of the project's location is not addressed, allowing the project team to focus on the building's priority issues
- B. The LEED project is able to skip a review phase by considering the issues that are a priority in the project's location
- C. The LEED project can achieve more sustainable outcomes by recognizing the issues that are a priority in the project's location
- D. The project's operations are considered separately from design and construction, allowing the project team to focus on regional issues
Answer: C
Explanation:
Explanation
A benefit of earning Regional Priority credits is that the LEED project can achieve more sustainable outcomes by recognizing the issues that are a priority in the project's location. Regional Priority credits are not new LEED credits, but instead are existing credits that USGBC regional councils and chapters have designated as being particularly important for their areas1. The incentive to achieve the credits is in the form of a bonus point. If an RP base credit is earned, then a bonus point is awarded to the project's total points1. This way, the project can address the geographically specific environmental, social equity and public health priorities of its location2. References:

NEW QUESTION # 21
A project team has installed a rainwater harvesting system on site. In which of the following could this system be recognized?
- A. Sustainable Sites Credit, Rainwater Management and Water Efficiency Credit, Indoor Water Use Reduction
- B. Water Efficiency Credit, Water Metering and Water Efficiency Prerequisite, Indoor Water Use Reduction
- C. Sustainable Sites Credit, Rainwater Management and Water Efficiency Prerequisite, Indoor Water Use Reduction
- D. Water Efficiency Credit, Water Metering and Water Efficiency Prerequisite, Outdoor Water Use Reduction
Answer: A
Explanation:
Explanation
A rainwater harvesting system on site could be recognized in the Sustainable Sites Credit, Rainwater Management and the Water Efficiency Credit, Indoor Water Use Reduction. The Sustainable Sites Credit, Rainwater Management rewards projects that reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site1. A rainwater harvesting system can help achieve this by capturing and reusing rainwater on site2. The Water Efficiency Credit, Indoor Water Use Reduction rewards projects that reduce indoor water consumption by installing water-efficient fixtures and fittings3. A rainwater harvesting system can help achieve this by providing an alternative source of water for non-potable uses such as toilet flushing and irrigation4.
The other options are not correct. The Water Efficiency Credit, Water Metering does not recognize rainwater harvesting systems, but rather requires projects to install permanent water meters that measure the total potable water use for the building and grounds. The Water Efficiency Prerequisite, Outdoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce outdoor water consumption by using plant species that are native or adapted to the region and by using irrigation systems that are efficient and properly controlled. The Water Efficiency Prerequisite, Indoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce indoor water consumption by 20% from the baseline by installing water-efficient fixtures and fittings.

NEW QUESTION # 22
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. Electronic submeter at the domestic water supply pipe to the building
- B. An open-loop HVAC system that discharges potable cooling water to a nearby lake
- C. A standard garbage disposal
- D. Commercial dishwasher that is ENERGY STAR labeled or performance equivalent
Answer: D
Explanation:
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.

NEW QUESTION # 34
A new five-story building with a 30,000 ft2 (2 800 m2) footprint is being designed on a previously disturbed100,000 ft2 (9 290 m2) site. The remaining on-grade surface will be 35,000 ft2 (3 250 m2) of asphalt parking, and 35,000 ft2 (3 250 m2) of native vegetated open space. To achieve a point for exemplary performance under Option 1 of Sustainable Sites Credit, Site Development - Protect or Restore Habitat, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of
- A. 12,500 ft2 (1 160 m2)
- B. 35,000 ft2 (3 250 m2)
- C. 25,000 ft2 (2 300 m2)
- D. 15,000 ft2 (1 400 m2)
Answer: C
Explanation:
Explanation
According to the LEED v4 Reference Guide for Building Design and Construction, Option 1 of the Site Development - Protect or Restore Habitat credit requires restoring 25% of the site area (including the building footprint) with native or adapted vegetation1. To achieve exemplary performance, the project must double the credit requirements and restore 50% of the site area2. In this case, the site area is 100,000 ft2 (9 290 m2), so the project must restore 50,000 ft2 (4 645 m2) with vegetation. The project already has 35,000 ft2 (3 250 m2) of native vegetated open space, so it needs to add another 15,000 ft2 (1 395 m2) of vegetation. Since the on-grade surface is fully occupied by the building footprint and the asphalt parking, the only option is to incorporate a vegetated roof. Therefore, the design team will have to incorporate a native and/or adapted vegetated roof with a minimum area of 15,000 ft2 (1 395 m2).

NEW QUESTION # 38
Which of the following will contribute to reducing the heat island effect?
- A. Steep sloped roof with initial SRI of 35
- B. Artificial turf grass
- C. Intensive vegetated roof
- D. Low sloped roof with initial Solar Reflectance Index (SRI) of 64
Answer: C
Explanation:
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. References:
