Rationale

Rationale: While LCA data regarding MEP systems has traditionally lagged behind building structure and envelope, there is increased interest in whole building LCA that includes this information. This proposed change clarifies that electrical, mechanical, and plumbing equipment, controls, fixtures, fire detection, alarm systems, elevators, are permitted to be included in the whole building LCA. This revision uses existing language contained within the document that satisfies the requirements of a standard practice. Additionally, two affirmative with comment voters suggested language edits have been incorporated into the proposed changes.
