The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) is seeking public input regarding the revision of an ASHRAE/IES standard addressing retrofit of existing residential and commercial buildings to achieve greater energy efficiency.

Public input is being sought on revisions to ANSI/ASHRAE/IESNA Standard 100-2006, Energy Conservation in Existing Buildings. Last year, ASHRAE and IESNA announced they were revising the standard to provide greater guidance and a more comprehensive approach to the retrofit of existing buildings for increased energy efficiency.
