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.
