- A. If a rating system is appropriate for 40% to 60% of the gross floor area, the project team must independently assess their situation and decide which rating system is most applicable
- B. If a rating system is appropriate for more than 50% of the gross floor area of LEED project space, then that rating system must be used
- C. If a rating system is appropriate for less than 50% of the gross area of the LEED project space then the rating system must not be used
- D. If a rating system is appropriate for 30% to 60% of the gross floor area, the project team must independently assess their situation and decide which rating system is most applicable
Answer: A
Explanation:
Explanation
According to the LEED v4: Building Design + Construction Guide, the 40/60 rule provides guidance for making a decision when several rating systems appear to be appropriate for a project. To use this rule, first assign a rating system to each square foot or square meter of the building, and then choose the most appropriate rating system based on the resulting percentages. The entire gross floor area of a LEED project must be certified under a single rating system and is subject to all prerequisites and attempted credits in that rating system, regardless of mixed construction or space usage type. If a rating system is appropriate for less than 40% of the gross floor area of a LEED project building or space, then that rating system should not be used. If a rating system is appropriate for more than 60% of the gross floor area of a LEED project building or space, then that rating system should be used.If an appropriate rating system falls between 40% and 60% of the gross floor area, project teams must independently assess their situation and decide which rating system is most applicable1.References: LEED v4: Building Design + Construction Guide, LEED Rating System Selection Guidance1

- B. The LEED project can achieve more sustainable outcomes by recognizing the issues that are a priority in the project's location
- C. The project's operations are considered separately from design and construction, allowing the project team to focus on regional issues
- D. The LEED project is able to skip a review phase by considering the issues that are a priority in the project's location
Answer: B
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 # 127
During a design charrette, community neighbors raise a concern about potential glare resulting from a project's highlyreflective roof. Which option should the LEED AP recommend to best address these concerns?
- A. Change the roofing material to a dark material to eliminate the issue
- B. Increase the parapet height
- C. Install a vegetative roofing system
- D. Change the design to reduce the amount of roofing area
Answer: C
Explanation:
Explanation
Installing a vegetative roofing system is the best option to address the potential glare resulting from a project's highly reflective roof. A vegetative roofing system, also known as a green roof, is a roof that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. A vegetative roofing system can reduce the reflectivity of the roof surface and mitigate the glare impact on the surrounding environment. It can also provide other benefits, such as reducing heat island effects, improving stormwater management, enhancing biodiversity, and increasing roof insulation. Therefore, option A is the correct answer. The other options are not as effective or desirable as installing a vegetative roofing system.
Changing the design to reduce the amount of roofing area (option B) may not be feasible or desirable, as it may compromise the project's program or performance. Changing the roofing material to a dark material to eliminate the issue (option C) may reduce the glare, but it will also increasethe heat absorption and emission of the roof, contributing to heat island effects and increasing cooling loads. Increasing the parapet height (option D) may block some of the glare, but it will also increase the material and construction costs, and it may not be sufficient to prevent glare from all angles.For more information on vegetative roofing systems and their benefits, you can refer to the LEED v4 Reference Guide for Building Design and Construction1or the Green Roofs for Healthy Cities website2.
