PORTLAND, OR -- Following its recent development of a life-cycle assessment (LCA) tool for evaluating building assemblies in green building rating systems, the Green Building Initiative (GBI) now intends to permit its consulting team to offer a free generic version to the entire sustainable construction community, according to Western Builder.

Developed for use with GBI's Green Globes environmental assessment and rating system for commercial buildings, the new software tool measures the global warming potential and other environmental impacts of more than 400 common building assemblies. Morrison Hershfield Consulting Engineers created the software, in association with the University of Minnesota's Center for Sustainable Building Research and the Athena Sustainable Materials Institute, and features LCA results generated by the Athena Environmental Impact Estimator software.

The GBI ANSI technical committee, prior to its integration into Green Globes, is reviewing the tool. GBI will authorize the Athena Sustainable Materials Institute to release a free generic version for use by other green building organizations, government entities, trade associations and universities.
