In response to comments received during the first public review (September 2007), this second public review draft makes independent substantive changes to the first PR draft. The standard as a whole is being revised to improve its alignment with related ASHRAE and ARI standards, especially ASHRAE Standard 37. Sections 6.6 through 6.13 from Standard 116-1995 (RA 2005) have been deleted and replaced by sections that refer the user to corresponding sections in Standard 37-2005. In addition, the proposed revision incorporates mandatory language throughout, adds the ASHRAE map of climate zones for US locations & updates references.
