Green Globes System to More Fully Integrate LCA
GBI has begun work to more fully incorporate life cycle assessment (LCA) into
the Green Globes environmental assessment and rating system, making it easier
to compare the cradle-to-grave environmental impacts of alternate building
designs.
LCA is a method used to assess the environmental performance of materials,
products and building assemblies over their entire life cycles—from
resource extraction, through manufacturing, transportation, installation and
ultimate disposal. Widely considered to be the only way to accurately and
impartially compare products and materials, it captures a variety of
environmental indicators, including (among others) fossil fuel depletion, water
use, global warming potential and stratospheric ozone depletion.
“Our objective is to make green building more accessible to the mainstream
design and building community,” said Ward Hubbell, executive director of
the GBI. “Green Globes already incorporates LCA to a limited degree. By
integrating it more fully into the system, we’ll make it easier for
design teams to compare the environmental impacts of alternate products and
materials—and to make informed, scientifically-based choices.”
As a first step, GBI has begun the process to assess and rate various building
assemblies using established LCA methodology. Once this data is integrated,
design teams will receive credit within Green Globes for using highly ranked
assemblies.
