LEED for Existing Buildings: Operations & Maintenance EAc1

This is the single most important credit in LEED, as reflected in the number of points available. Projects earn those points based on their Energy Star score, which is derived from their actual energy use during the performance period. Project types that are not elegible for Energy Star earn points based on their percent energy use reduction against a national baseline.
