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 .Reference: LEED v4 Green Associate Candidate Handbook, LEED v4 BD+C Reference Guide

A brownfield site is appropriate for development of LEED projects because it is a site that has been previously used for industrial or commercial purposes and may be contaminated by pollutants or hazardous substances. Developing a brownfield site can help reduce environmental impacts, such as soil erosion, habitat loss, and water consumption, by reusing existing infrastructure and restoring degraded land.LEED projects can earn credits for developing on brownfield sites under the Sustainable Sites category.Reference:LEED v4 BD+C Reference Guide, Sustainable Sites, page 35; Best Management Practice #14: Alternative Water Sources1

One of the requirements for the Sustainable Sites Credit: Rainwater Management is that projects must use Green Infrastructure (GI) and Low Impact Development (LID) techniques within the LEED project boundary. GI and LID are design approaches that mimic natural hydrologic processes to manage stormwater runoff at its source. GI and LID techniques include strategies such as rain gardens, bioswales, permeable pavements, green roofs, rain barrels, cisterns, and vegetated buffers. The other options are not requirements for the Sustainable Sites Credit: Rainwater Management. Maximizing open space within the LEED project boundary is a requirement for the Sustainable Sites Credit: Open Space. Calculating the total rainwater runoff for 75th percentile rainfall events is a requirement for the Sustainable Sites Credit: Site Assessment. Using a combination of both structural and non-structural measures to manage a 90th percentile rainfall event is an option for meeting Option 1 of the Sustainable Sites Credit: Rainwater Management.Reference: LEED Green Associate Candidate Handbook, page 27; USGBC, [Sustainable Sites], page 4-5.

Rainwater is the type of water that would be most useful for landscape irrigation when considering water conservation and water efficient landscaping.Rainwater is water that falls from the sky as precipitation, and it can be collected and stored in tanks, barrels, cisterns, or ponds for later use1.Rainwater is a renewable and free source of water that does not require any treatment or pumping, unlike potable water, which is water that is safe for human consumption and often comes from municipal sources2.Potable water is a scarce and valuable resource that should be conserved for drinking, cooking, and hygiene purposes, rather than for irrigation2.Clean water is a vague term that can refer to any water that is free of contaminants, but it does not necessarily mean that it is potable or suitable for irrigation3.Blackwater is water that contains human or animal waste, such as sewage or toilet water, and it poses a health and environmental risk if used for irrigation without proper treatment4.Therefore, rainwater is the best option for landscape irrigation, as it reduces the demand for potable water, lowers the utility bills, and benefits the plants and soil1.

Water Efficiency is the only credit category that does not have a prerequisite in LEED v4 for Building Design and Construction. Prerequisites are the minimum requirements that all projects must meet to be eligible for LEED certification. They are mandatory and non-weighted, meaning they do not contribute to the project's score. The other credit categories have at least one prerequisite each, as shown in the table below:

A salvaged wood door from another site qualifies under the Materials and Resources sustainable criteria of materials reuse. Materials reuse is the practice of using existing materials or products for new purposes without altering their form or composition. Materials reuse reduces the demand for virgin materials, saves energy and resources, and prevents waste generation. The other options are not applicable to a salvaged wood door from another site. Certified wood is wood that has been harvested from forests that are managed in an environmentally responsible, socially beneficial, and economically viable manner according to the standards of an accredited certification system such as the Forest Stewardship Council (FSC). Bio-based materials are materials that are derived from plants or animals, such as bamboo, cork, wool, or cotton. Waste diversion is the practice of diverting waste from landfills or incinerators by recycling, reusing, salvaging, or donating materials.Reference: LEED Green Associate Candidate Handbook, page 28; USGBC, [Materials and Resources], page 4.

When a project involves multiple rating systems, the project team must decide the most appropriate one based on the project's scope and primary objectives. LEED provides guidance to facilitate this decision.

Unless mitigated, resource consumption over the life of a conventional building incrementally increases the total emissions footprint. This is because conventional buildings often use non-renewable resources for energy and materials, which contribute to greenhouse gas emissions during extraction, production, use, and disposal.Reference: LEED Green Associate Candidate Handbook, U.S. Green Building Council resources
