A project team has installed a rainwater harvesting system on site. In which of the following could this system be recognized?
A rainwater harvesting system on site could be recognized in the Sustainable Sites Credit, Rainwater Management and the Water Efficiency Credit, Indoor Water Use Reduction. The Sustainable Sites Credit, Rainwater Management rewards projects that reduce runoff volume and improve water quality by replicating the natural hydrology and water balance of the site1. A rainwater harvesting system can help achieve this by capturing and reusing rainwater on site2. The Water Efficiency Credit, Indoor Water Use Reduction rewards projects that reduce indoor water consumption by installing water-efficient fixtures and fittings3. A rainwater harvesting system can help achieve this by providing an alternative source of water for non-potable uses such as toilet flushing and irrigation4.
The other options are not correct. The Water Efficiency Credit, Water Metering does not recognize rainwater harvesting systems, but rather requires projects to install permanent water meters that measure the total potable water use for the building and grounds. The Water Efficiency Prerequisite, Outdoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce outdoor water consumption by using plant species that are native or adapted to the region and by using irrigation systems that are efficient and properly controlled. The Water Efficiency Prerequisite, Indoor Water Use Reduction does not recognize rainwater harvesting systems, but rather requires projects to reduce indoor water consumption by 20% from the baseline by installing water-efficient fixtures and fittings.

Which of the following is an example of a diverse use as defined by Location and Transportation Credit, Surrounding Density and Diverse Uses?
Detailed
A public park qualifies as a diverse use under LEED because it is a publicly accessible facility that serves the community. LEED defines diverse uses as those that provide amenities, services, or public resources within walking distance, promoting walkable neighborhoods and reducing reliance on vehicles.
Which of the following products must always be included in Materials and Resources credits?
Interior paint must always be included in Materials and Resources credits. This is because interior paint is considered as a permanently installed product, which is defined by the LEED v4 Reference Guide for Building Design and Construction as 'a product that is installed in a project permanently or semi-permanently, such that removal would require demolition or substantial renovation.'1 Permanently installed products must be included in the calculations for the following Materials and Resources credits: Building Life-Cycle Impact Reduction, Building Product Disclosure and Optimization - Environmental Product Declarations, Building Product Disclosure and Optimization - Sourcing of Raw Materials, and Building Product Disclosure and Optimization - Material Ingredients.1 The other options are not always included in Materials and Resources credits. Faucets (option A) and fire suppression systems (option D) are considered as mechanical, electrical, and plumbing components, which are excluded from the scope of Materials and Resources credits unless they are specifically addressed by the credit requirements.1 Furniture (option B) is considered as a non-permanently installed product, which is optional to include in Materials and Resources credits, except for the Building Product Disclosure and Optimization - Material Ingredients credit, where furniture must be included if it is within the project scope.1 Reference: LEED v4 Reference Guide for Building Design and Construction, p. 5791; LEED v4 Reference Guide for Building Design and Construction, p. 5801; LEED v4 Reference Guide for Building Design and Construction, p. 5811; LEED v4 Reference Guide for Building Design and Construction, p. 5821; LEED v4 Reference Guide for Building Design and Construction, p. 5831
Which of the following must be included in the Sustainable Sites Credit, Site Assessment?
The correct answer is C. Proximity of vulnerable populations to major sources of air pollution.
According to the LEED v4.1 Reference Guide for Building Design and Construction, the Site Assessment credit requires projects to conduct and document a site inventory and analysis that covers the following topics1:
Topography
Hydrology
Climate
Vegetation
Soils
Human use
Human health effects
The human health effects topic includes identifying the proximity of vulnerable populations, such as children, elderly, or low-income residents, to major sources of air pollution, such as highways, power plants, or industrial facilities. This information can help the project team design strategies to minimize the exposure of occupants and visitors to harmful pollutants and improve the indoor and outdoor air quality of the project1.
The other options are not required for the Site Assessment credit, although they may be relevant for other credits or prerequisites. A targeted Brownfield remedy plan is required for the Brownfields Remediation credit, which applies to projects located on sites contaminated by past uses1. A historic preservation plan to include neighboring properties is not required for any LEED credit, although projects that involve historic buildings or districts must comply with local regulations and standards for preservation1. The surrounding density within a 1/4 mi. (0.40 km) radius of the project boundary is not required for the Site Assessment credit, but it is used to calculate the points for the Surrounding Density and Diverse Uses credit, which encourages projects to locate in areas with high levels of existing development and mixed land uses1.
The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will
The WaterSense label or local equivalent requirement in Water Efficiency Prerequisite, Indoor Water Use Reduction ensures that eligible newly installed plumbing fixtures will be both water efficient and high performing. The WaterSense label is a voluntary program by the U.S. Environmental Protection Agency (EPA) that identifies and promotes water-efficient products that meet EPA's specifications for water efficiency and performance. The label applies to tank-type toilets, water-using urinals, private lavatory faucets, and showerheads. For projects outside the U.S., local equivalents may be used if they meet the same criteria as WaterSense or are listed on the USGBC website. The label does not imply that the fixtures are LEED compliant, comply with mandatory federal government regulations, or comply with all international plumbing system requirements. Reference:
