A new threshold for energy performance goes into effect for all LEED 2009 projects registered on or after April 8, 2016. In addition to the required savings in EAp2, new projects will also have to earn at least 4 points in EAc1 to be certified.
This effectively raises the prerequisite savings to 18% and 14%, for new buildings and major renovations respectively, under the LEED-NC rating system. Other rating systems are also affected.
The referenced energy standard and requirements for modeling are unchanged. A summary of changes can be found in the USGBC document “LEED 2009 Energy Performance update.”
