For projects that decide to register for LEED under the 2009/v3 versions of the rating system on or after the effective date of April 8, 2016, USGBC has highlighted some important things to remember:
- The referenced standards will not change. The new minimum thresholds equate to a four-point minimum in the Optimize Energy Performance credit (except health care, where a three-point minimum is required). For new construction, this amounts to an 8 percent efficiency increase above the previous 10 percent requirement beyond ASHRAE 90.1-2007. Projects seeking to comply via prescriptive Options 2 and 3 will need to use a different pathway, as these options do not award a sufficient number of points. Projects may also use ASHRAE 90.1-2010 to comply, using the ASHRAE 90.1-2010 Adjusted Point Scale for LEED v2009 Projects.
