A project can earn up to four maximum points under the Regional Priority credit. The Regional Priority credit is a bonus credit that rewards projects for addressing environmental issues that are of regional importance. The USGBC regional councils and chapters have identified six environmental issues for each zip code in the United States, and projects can earn one point for each issue they address, up to a maximum of four points. The other options are not correct. One, two, or three points are possible, but not the maximum number of points under the Regional Priority credit. References: LEED Green Associate Candidate Handbook, page 30; USGBC, [Regional Priority], page 1.

The location valuation factor is a concept that applies to several credits under the Materials and Resources credit category in LEED v4. It means that if the purchased products or materials are extracted, manufactured, and purchased within 100 miles (160 kilometers) of the project, LEED will award the project in the credit calculations by valuing those products at 200% of their cost1. This is to incentivize the purchase of products that reduce transportation emissions and environmental impacts associated with long-distance shipping2.

Drip irrigation is a method of watering plants that delivers water directly to the roots through a network of pipes, tubes, valves, and emitters. Drip irrigation is not a plumbingfixture, but a landscaping technique that can reduce outdoor water use by minimizing evaporation, runoff, and overspray12.

Plumbing fixtures are devices that provide water for various purposes, such as washing, bathing, cooking, or flushing. Plumbing fixtures include urinals, showerheads, kitchen faucets, and other types of faucets, toilets, bidets, and sinks. Plumbing fixtures are subject to indoor water use reduction strategies in LEED certification, such as installing low-flow or high-efficiency models, using automatic sensors or timers, or implementing water reuse systems34.

Paved surfaces absorb and retain heat, increasing local temperatures and contributing to the heat island effect. LEED encourages mitigating this effect by using materials with high Solar Reflectance Index (SRI) or implementing strategies like green roofs and shaded areas​​.

The Facilities Manager is typically responsible for ensuring the comfort and safety of a building’s occupants. They would be best equipped to evaluate responses to a survey about comfort levels in the building and develop a corrective action plan to address any problems identified. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Monitoring outdoor airflow is a strategy for improving indoor environmental quality during construction. Outdoor airflow is the amount of fresh air that enters a building through natural or mechanical means. Monitoring outdoor airflow can help ensure that adequate ventilation is provided to the building during construction, which can prevent the accumulation of indoor pollutants, such as dust, debris, or volatile organic compounds, that may affect the health and comfort of the workers or occupants. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving indoor environmental quality is to “monitor outdoor airflow” [1, p. 16]. References: LEED Green Associate Candidate Handbook, [Outdoor Airflow | ASHRAE]

Resource depletion is a major environmental concern related to energy use. The extraction and use of non-renewable energy resources (such as fossil fuels) can lead to their depletion over time. This is why strategies that reduce energy use or utilize renewable energy sources are important in green building practices. References: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources

Gallons per minute or liters per minute refers to the amount of water used by flow fixtures in LEED. Flow fixtures are fixtures that deliver a constant stream of water, such as faucets, showerheads, or hose bibs. The flow rate of these fixtures is measured in gallons per minute (gpm) or liters per minute (L/min), which indicates how much water flows through them in a given time period. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to “use low-flow faucets and showerheads (maximum 2.5 gpm at 80 psi)” [1, p. 14]. References: LEED Green Associate Candidate Handbook, [Water Efficiency | U.S. Department of Energy]

The water use reduction for a project is determined by finding the difference between the baseline conditions and the calculated installed case. The baseline conditions are the water use of the project if it were designed to meet the minimum requirements of the Energy Policy Act of 1992 or a local equivalent, whichever is more stringent. The calculated installed case is the water use of the project based on the actual fixtures and fittings installed or specified. The water use reduction is calculated as a percentage of savings from the baseline conditions. The LEED Green Associate Candidate Handbook states that one of the strategies for achieving water efficiency is to “calculate water use reduction by comparing a building project’s water use with the water use baseline calculated for the building after meeting the Energy Policy Act of 1992 fixture performance requirements” [1, p. 14]. References: LEED Green Associate Candidate Handbook, [Water Use Reduction | U.S. Green Building Council]

LEED uses specific ASHRAE standards for energy and indoor air quality:

“ASHRAE 90.1-2010 is used for Minimum Energy Performance...”

“ASHRAE 62.1-2010 is used for Minimum Indoor Air Quality Performance...”

SMACNA is related to construction air quality, not performance standards.
