USGBC Members Vote to Update Minimum Energy Efficiency Requirements for LEED BD+C and ID+C v3 Rating Systems

Yesterday, USGBC announced its members approved a ballot measure that updates the minimum energy efficiency requirements for LEED BD+C and ID+C v3 rating systems (including LEED 2008 Multifamily Mid-Rise). The change is effective for projects registering for LEED v3 certification (also called LEED 2009) using these rating systems on or after April 8, 2016. This update does not affect LEED 2009 O+M, ND or LEED 2008 Homes.

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.
