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

Answer : C

The intent of waste management in the Materials and Resources credit category is to reduce the amount of waste and toxins hauled to landfills. This can be achieved through strategies such as recycling, composting, reusing materials, and reducing overall material consumption. By reducing waste, we can conserve natural resources, reduce pollution from waste treatment and disposal processes, and decrease the demand for landfill space.Reference: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Answer : B

Increasing the cycles of concentration in a cooling tower system is the best answer because cooling towers are a major source of process water use in many commercial buildings. Higher cycles of concentration mean water is reused more times before blowdown is required, reducing makeup water demand while maintaining efficient operation when water quality is properly managed. Submetering helps track consumption and identify problems, but measurement alone does not reduce water use. Low-flow kitchen spray valves reduce water use in kitchen operations, but the question focuses on process systems, especially building systems such as cooling towers. Increasing once-through cooling is incorrect because it wastes large amounts of potable water and is discouraged in sustainable water design. Cooling tower water management is a key Water Efficiency strategy.

Answer : C

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.

Answer : C

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 : B

The statement that is the U.S. Green Building Council (USGBC) vision is: Buildings and communities will regenerate and sustain the health and vitality of all life within a generation. USGBC is a non-profit organization that promotes sustainability in the building industry through its LEED rating system, education programs, advocacy initiatives, and research projects.USGBC's vision reflects its commitment to transformingthe built environment into one that supports human health, environmental quality, social equity, and economic prosperity1.Reference: LEED v4 Green Associate Candidate Handbook1, USGBC's Vision

Answer : A

Selection of low-emitting materials is the correct answer because LEED Indoor Environmental Quality addresses pollutants that can affect indoor air quality and occupant health. Materials with high VOC content, added formaldehyde, or harmful chemical emissions can off-gas into interior spaces and cause irritation, odor, discomfort, or health concerns. Low-emitting materials credits encourage products such as compliant paints, adhesives, sealants, flooring, insulation, furniture, and composite wood with no added formaldehyde resins where applicable. Salvaged materials may reduce resource impacts, but they do not automatically guarantee low emissions. Low carbon materials address embodied carbon, mainly a Materials and Resources concern. Lowest first cost is not a LEED health-based material selection strategy.

Answer : A

The cradle-to-cradle approach to sustainable materials evaluates building materials from extraction to reuse, which means that the materials are considered as part of a continuous cycle of use and regeneration, rather than a linear process of consumption and disposal. The cradle-to-cradle approach aims to eliminate waste and pollution, conserve resources and energy, and create positive impacts for the environment and human health.The cradle-to-cradle approach is based on the principles of eco-effectiveness, which include designing products and systems that are safe and healthy for humans and nature, using renewable energy and clean water, celebrating diversity and creativity, and respecting social and environmental justice12.The cradle-to-cradle approach is also recognized and encouraged by LEED v4, which includes a credit for using products that have achieved Cradle to Cradle certification34.
