Continuous improvement ensures that the LEED rating systems stay relevant in a time when policies, technologies and the needs of the industry are constantly changing. In the last three years, residential construction energy codes rapidly have become more stringent, a trend we anticipate will continue. The updates in LEED v4 (the newest version of LEED for Homes) respond to these changes, and now USGBC aims to update the 2008 version of LEED for Homes by beginning an official update process.
This update to LEED for Homes v2008 will increase the stringency of the energy prerequisite by roughly 15%, approximately equivalent to the energy performance of ENERGY STAR v3, 15% above International Energy Conservation Code (IECC) 2009 and equivalent to IECC 2012. Projects using LEED for Homes v2008 would need to earn a minimum of 13 points in the Energy & Atmosphere (EA) section for climate zones (CZ) 1-5, or 9.5 points for CZ 6-8. The threshold change would require projects to achieve a Home Energy Rating System (HERS) score of 70 or lower, or earn the equivalent number of points in the prescriptive path. Currently, over 90% of all certified projects are scoring lower than a HERS 70.
