Embodied Energy: Energy use includes extraction, processing, transportation,
construction, and disposal of each material. Assumptions: Low rise building.
Values are general estimations for the U.S. 60 year building lifetime. Low-e,
double-pane, argon-filled glazing. All assemblies are insulated to IECC 2009
minimums for zones 3 and 6. |
