Important US Green Building Council LEED-Green-Associate Exam Questions

Answer: C

Explanation:

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].Reference:LEED Green Associate Candidate Handbook, [Ozone Depletion Potential | U.S. Environmental Protection Agency]

Answer: C

Explanation:

Existing local land-use patterns are the best answer because an early site assessment helps the project team understand how the site relates to its surrounding context. LEED Sustainable Sites encourages assessment of existing site conditions before major design decisions are made. This includes topography, hydrology, climate, vegetation, soils, human use, adjacent properties, transportation infrastructure, and human health effects. Understanding local land-use patterns helps the team make decisions that support resilience, access, community compatibility, and reduced environmental disturbance. Selecting a site only because it is near the city center is too narrow and may ignore sensitive land or site constraints. Cultural significance may be relevant, but land-use patterns are broader and more directly connected to sustainable site planning. Furniture layout is not part of site assessment.

Answer: D

Explanation:

An infill site within an existing neighborhood with substantial transit connectivity would maximize LEED points under Location and Transportation. An infill site is a site that has been previously developed or graded and is surrounded by existing development. An existing neighborhood is a geographic area with a variety of land uses, such as residential, commercial, educational, or recreational. Substantial transit connectivity means that the site has access to multiple modes of public transportation, such as buses, trains, light rail, or bicycles. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to ''encourage development within existing communities and public transit infrastructure'' [1, p. 12].Reference: [LEED Green Associate Candidate Handbook], [Location and Transportation | U.S. Green Building Council]

Answer: A

Explanation:

Recycling is a strategy that can be used during the building process and after occupation to reduce waste. Recycling involves collecting, sorting, processing, and reusing or selling materials that would otherwise be discarded as waste.Recycling can save natural resources, reduce greenhouse gas emissions, create jobs, and lower disposal costs1.Recycling can also help to achieveLEED credits in the Materials and Resources category by reducing the amount of construction and demolition waste generated by the project or by diverting waste from landfills or incinerators.Reference: LEED v4 Green Associate Candidate Handbook1, EPA's Recycling Basics2, LEED v4 BD+C Reference Guide

Answer: B

Explanation:

LEED MPRs state:

''Must be in a permanent location on existing land... Must use reasonable LEED boundaries... Must comply with project size requirements: BD+C and O+M: minimum 1,000 sq ft...''

Only option B satisfies all these conditions.
