LEED-Green-Associate Exam Dumps : LEED Green Associate GAFRE Exam (LEED GA)

Green Seal is a third-party certification program that evaluates the environmental impacts of cleaning products and services. It has standards for various categories of products, such as cleaners, paper products, hand soaps, and floor care. Green Seal certified products meet rigorous performance, health, and environmental criteria. By using Green Seal certified products, projects can reduce the exposure of building occupants and maintenance personnel to potentially harmful chemicals, improve indoor air quality, and support sustainable purchasing practices. References: LEED v4 Reference Guide for Building Operations and Maintenance, p. 109 1; Green Seal website

R-12 is the correct answer because it is a chlorofluorocarbon (CFC) refrigerant, and CFCs are known for high Ozone Depletion Potential. LEED Energy and Atmosphere includes refrigerant management requirements to reduce damage to the stratospheric ozone layer and limit climate impacts from HVAC & R systems. New LEED projects must avoid CFC-based refrigerants in new HVAC & R systems, and existing systems with CFCs generally require replacement, retrofit, or a phase-out plan. R-134a and R-410A are non-CFC refrigerants and do not have the same ozone depletion impact as CFCs, though they may still have global warming impacts. Ammonia has no ozone depletion potential but has safety and application considerations.

Xeriscaping is a landscaping practice that uses drought-tolerant native and adaptive plants to reduce water use and maintenance. Xeriscaping also incorporates other strategies such as mulching, efficient irrigation, soil improvement, and appropriate design and zoning. By using xeriscaping, projects can conserve water, protect natural habitats, reduce stormwater runoffand pollution, and enhance the aesthetic and ecological value of the site. References: LEED v4 Reference Guide for Building Design and Construction, p. 123 1; [Xeriscape Colorado website]
