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]

The Materials and Resources Credit category calculation addresses the permanently installed building products that are part of the building’s structure, enclosure, and interior elements. These include framing, flooring, insulation, windows, doors, interior walls, ceilings, and finishes. Process equipment, elevators, furniture, and formwork for concrete are not included in the calculation . References: LEED v4 Green Associate Candidate Handbook, LEED v4 BD+C Reference Guide

ENERGY STAR Portfolio Manager is an online tool developed by the U.S. Environmental Protection Agency (EPA) that allows building owners and managers to measure and track the energy and water performance of their buildings, as well as benchmark their buildings against similar buildings nationwide. The tool uses a 1-100 ENERGY STAR score to rate the energy efficiency of a building relative to its peers, where a score of 50 represents median performance and a score of 75 or higher indicates top performance1 . References: LEED v4 Green Associate Candidate Handbook1, ENERGY STAR Portfolio Manager

Potable water is water that is suitable for drinking. Potable water meets or exceeds the Environmental Protection Agency’s (EPA) drinking water quality standards and is free of contaminants that are harmful to human health. The other options are not suitable for drinking. Graywater is wastewater from sinks, showers, and laundry that can be reused for non-potable purposes such as toilet flushing and irrigation. Greenwater is rainwater that is collected and stored for non-potable uses. Stormwater is runoff from precipitation that can carry pollutants and sediments into waterways. References: LEED Green Associate Candidate Handbook, page 26; USGBC, [Water Efficiency], page 2.
