Use durable products and materials. Because manufacturing is very energy-intensive, a product that lasts longer or requires less maintenance usually saves energy. Durable products also contribute less to our solid waste problems. Choose building materials with low embodied energy. Buy locally produced building materials.
Transportation is costly in both energy use and pollution generation.
Use building products made from recycled materials. Building products made from recycled materials reduce solid waste problems, cut energy consumption in manufacturing, and save on natural resource use. A few examples of materials with recycled content are cellulose insulation, Homosate, Thermo-ply, and recycled plastic lumber. Use salvaged building materials when possible. Minimize use of old-growth timber.
