Standard 90.1 Addenda To Be Reviewed
ATLANTA - There are 15 proposed addenda to ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings. Providing minimum requirements for the energy-efficient design of buildings except low-rise residential buildings, the addenda address requirements to lessen energy use and costs through fenestration, parking lot lighting, and other proposed measures open for public review.
“As the industry continues to call for buildings and systems that use less energy, the Standard 90.1 committee is striving to find ways to reduce energy uses and costs,” Mick Schwedler, chair of the Standard 90.1 committee, said. “The proposed changes not only reduce energy use but move the standard closer to the work plan goal of a 2010 standard, with 30 percent energy cost savings compared to the 2004 standards.”
Among the proposed addenda out for public comment is addendum cd, which would require active exterior control rather than just require the control capability; add bi-level control for general all-night applications, such as parking lots to reduce lighting when not needed; and add control for façade and landscaping lighting not needed after midnight.
Proposed addendum bb updates building envelope requirements for opaque elements, such as walls and rooms, and fenestration (windows and skylights). A number of changes were made in response to public comments during the first public review.
“I would like to thank all of those who met with the Standard 90.1 committee during our fall interim meetings for their candor, input, and willingness to work toward an addendum that can reach consensus and save both energy and energy costs,” said Schwedler.
The proposed addenda to ASHRAE/IESNA Standard 90.1 are available for comment only during their public review periods.
