An infill site within an existing neighborhood with substantial transit connectivity would maximize LEED points under Location and Transportation. An infill site is a site that has been previously developed or graded and is surrounded by existing development. An existing neighborhood is a geographic area with a variety of land uses, such as residential, commercial, educational, or recreational. Substantial transit connectivity means that the site has access to multiple modes of public transportation, such as buses, trains, light rail, or bicycles. The LEED Green Associate Candidate Handbook states that one of the intents of the Location and Transportation category is to “encourage development within existing communities and public transit infrastructure” [1, p. 12]. References: [LEED Green Associate Candidate Handbook], [Location and Transportation | U.S. Green Building Council]

A waste reduction, reuse and recycling program must collect and measure the waste diverted through recycling and reuse, which is the amount of waste that is prevented from going to landfills or incinerators by being recovered, reused, or recycled. This is one of the key indicators of the environmental performance and benefits of a waste management program, as it can reduce greenhouse gas emissions, conserve natural resources, save energy and water, and create jobs. LEED v4.1 recognizes and rewards this strategy in the Construction and Demolition WasteManagement credit1, which aims to reduce construction and demolition waste disposed of in landfills and incineration facilities2. The other options are not directly related to the waste reduction, reuse and recycling program, as they involve different types of materials or metrics that are not relevant for measuring waste diversion. References: LEED Link: Construction and Demolition Waste Management, section “LEED v4.1 BD+C: Construction and Demolition Waste Management”; LEED v4 Waste Management Credits - Zero Waste, section “LEED v4 Waste Management Credits”

The project team’s strategy of using low-flow toilet fixtures and integrating non-potable water strategies for the building interior falls under the Water Efficiency category. The Water Efficiency category addresses the conservation and management of water resources in buildings and landscapes. Using low-flow toilet fixtures reduces the amount of potable waterused for flushing toilets, saving water and energy. Integrating non-potable water strategies for the building interior involves using alternative sources of water, such as rainwater, graywater, or reclaimed water, for non-potable purposes such as toilet flushing or irrigation, reducing the demand for potable water and wastewater generation. The other options are not categories that this strategy falls under. Innovation is a category that recognizes exemplary performance, innovative strategies, or pilot credits that are not covered by existing LEED credits. Sustainable Sites is a category that addresses the selection, development, and maintenance of project sites in ways that minimize environmental impacts and enhance human health and well-being. Optimized Process Water Use is not a LEED category or credit. References: LEED Green Associate Candidate Handbook, page 31; USGBC [Water Efficiency], page 1-2.

LEED certification is awarded based on the number of points a project earns across several categories of green building performance. The range of points required to achieve the Certified level of certification for the commercial LEED Rating System is 40-49, out of a possible 110points. The other levels of LEED certification are: Silver (50-59 points), Gold (60-79 points), and Platinum (80 or more points)12. References: LEED v4 Green Associate Candidate Handbook1, LEED v4 BD+C Reference Guide2
