Free Practice Questions for USGBC LEED-Green-Associate Exam

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. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Daylighting is a strategy that uses natural light to illuminate the interior spaces of a building, reducing the need for artificial lighting and improving the visual comfort and well-being of the occupants. One of the strategies that can help improve daylighting in an office building is tolocate private offices toward the building core and organize cubicles at the perimeter, so that more people can benefit from the access to windows and views. This can also increase the daylight penetration depth and reduce glare and contrast12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

Regional priority credits are bonus points that are awarded to projects that achieve credits that address geographically specific environmental, social equity and public health priorities. These 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 areas. The goal of regional priority credits is to incentivize project teams to address the most critical and relevant environmental issues in their regions, such as water scarcity, air quality, habitat loss, or social equity12. Regional priority credits are based on the project’s geolocation (latitude and longitude coordinates), which can be entered and confirmed during project registration in LEED Online2. Each project can earn up to four regional priority bonus points, one for each regional priority credit achieved3.

ASHRAE 62.1 is the standard for ventilation and acceptable indoor air quality in commercial and institutional buildings. It specifies the minimum ventilation rates and other measures to provide good indoor air quality for occupants. LEED v4 references ASHRAE 62.1 as a prerequisite for the Indoor Environmental Quality credit category.

ASHRAE 62.1 from the LEED v4 Green Associate Candidate Handbook, page 18.

Enhance Indoor Environmental Quality (IEQ) from the WBDG website, section on Adequate Ventilation and Exhaust.

LEED promotes compact, transit-rich locations:

“Locating a project in an area that supports walking, biking, and mass transit... will result in lower GHG emissions from reduced car travel.”

Urban centers offer the best access to alternative transport and reduce reliance on fossil fuels.

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.
