The 20% energy efficiency improvement option in LEED-EBOM: Does it water down LEED, or help transform the market?

Minimum Energy Efficiency Performance solidify this prerequisite’s status as the gatekeeper for the LEED-EBOM program. The prerequisite requirements have been beefed up to a minimum Energy Star rating of 75 for ratable buildings or better than 75% of similar buildings for those not eligible for an Energy Star rating. The basic mechanics of documenting compliance appear to be the same as those in v2009, and maybe what’s most notable about the prerequisite is that an option included in the 2nd round of public comments that offered an alternative compliance path for buildings to demonstrate a 20% improved performance over their historic baseline has been removed. Removal of that option plus the heightened minimum Energy Star rating guarantees that the maximum total market share for LEED in the existing building arena is limited to just about a quarter of all buildings.
