Abstract/OtherAbstract:
We examined the potential life-cycle environmental impact reduction of three green building code and certification (GBCC) systems: LEED®, ASHRAE 189.1, and IgCC. A recently completed whole-building life cycle assessment (LCA) database of NIST was applied to a prototype building model specification by NREL. TRACI 2.0 of EPA was used for life cycle impact assessment (LCIA). The results showed that the baseline building model generates about 18 thousand metric tons CO2-equiv. of greenhouse gases (GHGs) and consumes 6 terajoule (TJ) of primary energy and 328 million liter of water over its life-cycle. Overall, GBCC-compliant building models generated 0% to 25% less environmental impacts than the baseline case (average 14% reduction). The largest reductions were associated with Acidification (25%), Human Health-Respiratory (24%) and Global Warming (GW) (22%), while no reductions were observed for Ozone Layer Depletion (OD) and Land Use (LU). The performances of the three GBCC-compliant building models measured in life-cycle impact reduction were comparable. A sensitivity analysis showed that the comparative results were reasonably robust, although some results were relatively sensitive to the behavioral parameters, including employee transportation and purchased electricity during the occupancy phase were relatively sensitive to the results (average sensitivity coefficients 0.26-0.29).
