Sept. 19, 2014: Verification Requirements Proposed for ASHRAE/IES Energy Standard
Addendum Is One of 14 Proposed to ANSI/ASHRAE/IES Standard 90.1-2013
ATLANTA — Multiple compliance options to ensure verification of delivered building envelope performance are being proposed for the ASHRAE/IES energy standard.
“Uncontrolled air leakage has long been an unquantified variable in load calculations for buildings large and small,” said Chris Mathis, a member of the committee who helped to develop the proposal. “It has also been identified as the ‘weak link’ in many otherwise well insulated building enclosures. These newly proposed envelope testing, inspection, and verification procedures are intended to not only help deliver better performing building envelopes, but also should help reduce errors associated with envelope air leakage in equipment sizing calculations.”
