602.8 Termite-resistant Materials: Use termite-resistant construction materials appropriate for the level of termite infestation probability as defined by the NAHB National Green Building Standard. 2-6
604.1 Recycled-content Materials: Use recycled-content building materials for two minor and/or two major components of the building with a recycled content of 25% or greater. (CedarBoards only) 2-4
605.3 Construction Materials are Recycled Offsite: Construction materials such as wood, cardboard, metals, drywall, plastic, etc., are recycled offsite. 3
608.1 Locally Available, Indigenous Materials: Use indigenous materials for major elements of the building. 2
609.1 Use LCA to Determine Most Environmentally Preferable Material: A more environmentally preferable product or assembly is selected for an application based on the use of a Life Cycle Assessment (LCA) tool compliant with ISO 14044 or other recognized standards that compare the environmental impact of building materials, assemblies or the whole building. 3
Energy Efficiency
