USGBC Updated LEED-Green-Associate Exam Questions and Answers by hadiya

 LEED is an acronym for Leadership in Energy and Environmental Design, which is the most widely used green building rating system in the world. LEED provides a framework for creating healthy, efficient, and cost-saving buildings that have positive environmental and social impacts. LEED certification is a globally recognized symbol of sustainability achievement and leadership12.

The Guide specifies:

“Use nonpotable water for irrigation such as captured rainwater, graywater or municipally reclaimed wastewater…”

Potable water use is discouraged, and blackwater cannot be used unless treated.

One of the values and benefits of building green is that it will enhance the health of the building occupants. Building green is a process that incorporates environmental considerations into every stage of a building’s life cycle, from design to construction to operation to end-of-life. Building green can improve the indoor environmental quality (IEQ) of a building, which is the physical and psychological conditions of the indoor spaces that affect the health, comfort, and productivity of the occupants. Building green can enhance IEQ by using low-emitting materials, providing adequate ventilation, controlling temperature and humidity, optimizing daylighting and lighting quality, reducing noise levels, and promoting occupant well-being12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2

Strategically locating functional and decorative hardscape on a project site can reduce the amount of on-site impervious area. Impervious surfaces are surfaces that do not allow water to infiltrate into the ground (e.g., concrete or asphalt). By reducing these surfaces, we can increase water infiltration, which helps recharge groundwater supplies and reduces stormwater runoff that can lead to erosion and water pollution. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
