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

Building commissioning is a quality assurance process that begins during the design phase and continues through construction, occupancy, and operation of the building. It ensures that the building’s systems are designed efficiently, installed correctly, and operate as intended. The commissioning process involves a series of inspections, tests, and adjustments of building systems, followed by a review of the system design and operation with the building’s operations team. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Construction IAQ management and LEED strategies directly improve health:

“Using proper construction management practices… protects worker and occupant health by controlling pollutant sources and pathways…”

High VOC materials and low ventilation have adverse effects, not benefits.

Rainwater is considered an alternative water source because it is a sustainable source of water that is not supplied from fresh surface water or groundwater. Rainwater can be harvested from roofs or other surfaces and stored for later use. Rainwater can offset the demand for freshwater and reduce the pressure on water resources. Rainwater can be used for various purposes, such as irrigation, toilet flushing, cooling, and cleaning. LEED projects can earn credits for using alternative water sources under the Water Efficiency category. References: Best Management Practice #14: Alternative Water Sources1; LEED v4 BD+C Reference Guide, Water Efficiency, page 51

impervious surfaces are those that do not allow water to infiltrate into the soil, such as asphalt, concrete, roofs, or compacted soil. Impervious surfaces increase the amount and speed of stormwater runoff, which can cause erosion, sedimentation, flooding, and pollution of downstream water bodies. Minimizing impervious surfaces can help reduce these negative impacts and preserve the aquatic habitat and natural stream morphology12.

Native vegetation is the plant life that is adapted to the local climate and soil conditions. Native vegetation can help filter pollutants, stabilize soils, reduce runoff, provide shade, and create habitat for wildlife. Enhancing native vegetation can help restore the natural functions and diversity of the ecosystem and protect the aquatic habitat and natural stream morphology13.

Rainwater is the precipitation that falls on the site. Rainwater can be captured and reused for various purposes, such as irrigation, toilet flushing, or cooling. Capturing and reusing rainwater can help reduce potable water demand, decrease stormwater runoff, and prevent flooding and pollution of downstream water bodies. Capturing and reusing rainwater can help conserve water resources and protect the aquatic habitat and natural stream morphology1 .

These strategies are consistent with the LEED v4 requirements for the Sustainable Sites credit category, which aims to protect and restore habitat, manage stormwater, reduce heat island effects, and promote alternative transportation.
