ASHRAE has been a leader in the green and sustainable buildings, developing a variety of “better-than-code” standards, historically focused on commercial building performance. As part of its increased commitment to residential building performance initiatives, ASHRAE partnered with ICC and NAHB in the revision to the 2012 Residential Green Building Standard. Drawing from experience with 189.1 and a number of building performance topics, ASHRAE delegates participated in development and deliberations on hundreds of proposed changes to ICC 700. This presentation will report on how the next edition of ICC 700 aligns with ASHRAE’s mission, technical rigor and professional standards requirements.
