Depending on the materials selected, the lifespan of the building, and its performance, operating energy can have much higher life-cycle impacts than construction or demolition. While the reference standard for this option does include this end use, the LEED credit does not—and it’s because you’re already receiving credit elsewhere in the LEED rating system for reducing operating energy. The scope of this credit is only focused on impact reductions from building materials.
Question
How does the LCA consider operating energy? Isn’t that going to be the biggest source of environmental impacts?
