LIFE CYCLE ASSESSMENT OF RESIDENTIAL BUILDINGS

摘要: Residential building construction represented about 4.2% of the US Gross Domestic Product in 2000, and residences consumed nearly 20% total energy consumption. However, design residential buildings is often not conducted with an analysis life cycle costs environmental impacts. In this paper, we outline approach to a for residences, using results typical cost estimate map into tools assessment (using Carnegie Mellon economic input-output model) resources required during use phase DOE Energy Saver model). essence, material are mapped sectors EIO-LCA model applied assess Similarly, operating inputs such as electricity or natural gas estimated from Home sectors. The result our toolset based upon estimate. We limited impacts calculated by assessment.
