LEED-Green-Associate Exam Dumps - USGBC Leadership in Energy and Environmental Design (LEED) Questions and Answers

Chlorofluorocarbons (CFCs) are the class of refrigerants that contribute the most to ozone depletion potential (ODP). Ozone depletion potential is a measure of how much a substance can damage the ozone layer in the stratosphere, which protects life on Earth from harmful ultraviolet radiation. CFCs are synthetic chemicals that contain chlorine, fluorine, and carbon atoms. They were widely used as refrigerants, aerosol propellants, solvents, and foam blowing agents until they were phased out by the Montreal Protocol due to their high ODP. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving energy and atmosphere efficiency is to “eliminate chlorofluorocarbons (CFCs) in new building HVAC & R systems” [1, p. 15]. References: LEED Green Associate Candidate Handbook, [Ozone Depletion Potential | U.S. Environmental Protection Agency]

The Integrative Process Credit in LEED v4 requires the project team to implement an integrative process that enables themto discover unique opportunities for enhancing project performance and environmental benefits1. The project team should identify and use opportunities to achieve synergies across disciplines and building systems2.

According to the LeadingGreen Study Guide:

" The first step in the certification process is the Project Registration. Projects can be registered on the GBCI website (www.gbci.org)... Before registration, the process begins with selecting the appropriate rating system using the 40/60 rule... "

Thus, selecting the correctrating systemis the initial key step before registration and documentation submission. The selection ensures alignment with the project type and its characteristics.

Stormwater runoff can indeed be treated and used in a facility’s cooling towers. This is an example of using non-potable water (water that is not of drinking quality) for purposes that do not require potable water. Other uses for treated stormwater might include toilet flushing or irrigation. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Daylighting falls under the Indoor Environmental Quality category. LEED awards points for strategies that enhance natural light to improve occupant comfort and reduce energy consumption​​.

Open-grid paving is a permeable hardscape strategy that allows rainwater to infiltrate through the surface rather than running off quickly into storm drains. In LEED Sustainable Sites, rainwater management aims to maintain or restore natural hydrology, reduce runoff volume, improve water quality, and limit downstream erosion and sedimentation. Option A is incorrect because alternative transportation is supported by strategies such as bicycle facilities, access to transit, reduced parking footprint, and green vehicles. Option B is incorrect because light pollution is addressed through exterior lighting design and fixture control. Option C is not the best answer because paving a parking area does not preserve native habitat, although it may reduce runoff impacts compared with conventional asphalt.

An owner who wants to update the interior materials of the office while promoting a healthier indoor work environment using LEED strategies can specify low-emitting materials as one of the strategies to achieve this goal. Low-emitting materials are materials that have low or no emissions of volatile organic compounds (VOCs) or other pollutants into the indoor air. VOCsare organic chemicals that can evaporate or vaporize at room temperature and can adversely affect the indoor air quality (IAQ) of a building and the health, comfort, and productivity of the occupants. Some sources of VOCs in buildings are paints, coatings, adhesives, sealants, flooring, furniture, and cleaning products. Specifying low-emitting materials can reduce the exposure and risk of VOCs for the occupants and improve IAQ12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2
