As of April 8, 2016, new LEED 2009 projects must demonstrate an 18% improvement in the proposed building performance rating for new buildings, or a 14% improvement in the proposed building performance rating for major renovations to existing buildings. The previous requirements were 10% for new construction and 5% for major renovations.
That means a project must achieve a minimum of 4 points under EAc1. Thus the old Option 2/3 paths are no longer permissible, meaning that energy modeling is now mandatory.
LEED 2009 (v3) will be phased out on October 31, 2016 to make way for LEED v4.
But here is the good news: LEED projects that enroll in the Xcel EDA program may be eligible for free LEED energy modeling and documentation. Contact Energetics to find out how.
