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

A drip irrigation system provides maximum water efficiency for a building irrigation system. A drip irrigation system delivers water directly to the root zone of plants, minimizing evaporation, runoff, and overspray. This reduces water consumption and prevents water pollution from fertilizers and pesticides. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency in landscaping is to “use efficient irrigation systems, such as drip irrigation” [1, p. 14]. References: LEED Green Associate Candidate Handbook, [Drip Irrigation | U.S. Department of Agriculture]

Installing operable windows is the best answer because it gives occupants some control over ventilation and comfort conditions. Thermal comfort is influenced by air temperature, radiant temperature, humidity, air movement, clothing, and activity level. Because occupants have different preferences, LEED Indoor Environmental Quality supports strategies that improve comfort and, where possible, provide individual or group controls. Operable windows can help occupants adjust air movement and fresh air when outdoor conditions are appropriate. Task lighting improves visual comfort and may slightly reduce overhead lighting loads, but it is not primarily a thermal comfort strategy. A building-wide strategy based only on average benchmarks may leave many occupants dissatisfied. Removing occupant control is incorrect because control is often associated with improved comfort, satisfaction, and productivity.

According to the LeadingGreen Study Guide:

" The first step in the certification process is the Project Registration. Projects can be registered on the GBCI website (www.gbci.org)... Before registration, the process begins with selecting the appropriate rating system using the 40/60 rule... "

Thus, selecting the correctrating systemis the initial key step before registration and documentation submission. The selection ensures alignment with the project type and its characteristics.

Building-Level Water Metering is a prerequisite in LEED v4 Water Efficiency category. Building-Level Water Metering means that the project must install permanent water meters that measure the total potable water use for the building and associated grounds. The project must also commit to sharing the water usage data with USGBC for at least five years after occupancy or certification. The LEEDGreen Associate Candidate Handbook states that this is one of the two prerequisites in the Water Efficiency category [1, p. 14]. References: [LEED Green Associate Candidate Handbook] , [Building-Level Water Metering | U.S. Green Building Council]
