When we think of greenhouse gas emissions, most of us envision a tailpipe spewing exhaust out of the back of a car. But 40% of the carbon dioxide that contributes to our warming planet comes from buildings. While some of that is a secondary effect of operational needs such as electricity, A/C, and heating, many GHG’s arise from resource extraction, manufacturing and production of the building materials themselves.
Of all the criteria covered by LEED-H and our own GreenBuilding 101 series, MATERIALS and RESOURCES has perhaps the broadest application and relevance. They are the ingredients, and choosing them wisely makes all the difference in terms of the overall impact of the building throughout its life. This is where ‘environmental footprint’ or ‘life cycle assessment’ come into play; as we learn in Cradle to Cradle design basics, the materials are in the picture from the first round of planning to the final stages of demolition or renovation.
Today’s series walks you through choosing ingredients wisely, being sure that the materials you select, and the resources it took to produce them, are a part of the whole picture of a sustainable home.
