SIPS.org is making a free pdf copy of the NAHB's - 2015 Edition National Green Building Standard (NGBS): ICC/ASHRAE 700-2015 available.
This is the first residential green building standard to undergo the full consensus process and receive approval from American Ntl Standards Inst. (ANSI). NAHB, International Code Council (ICC) and a new partner (ASHRAE) all worked together to provide technical guidance for the development of this nationally recognized 3rd edition. It is important to note that LEED-Homes is not a 3rd party based consensus standard.
SIPA is providing this free PDF copy on our website. Jack Armstrong, Executive Director of SIPA, sat on one of the committees reviewing this update. Click here to view the pdf file
