Changes to the purpose and scope of ASHRAE/IESNA Standard 90.1 - Energy Standard for Buildings Except Low-Rise Residential Buildings - are being proposed through public review until Feb. 2.

ANSI/ASHRAE/IESNA Standard 90.1-2007 provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings.

Among the proposed addenda out for public review is addendum aq, which proposes changes to the purpose and scope of the standard. The proposed modification addresses applications not covered in the existing standard scope, such as requirements for laboratories, data center cooling and kitchen exhausts. It would also permit the 90.1 committee to address technologies, such as computer equipment and refrigerated casework, and would extend existing requirements for envelope, space cooling and lighting to a larger group of spaces where energy is consumed.

Standard 90.1 currently addresses design and construction of buildings. The proposed addendum would add operation and maintenance, which allows incorporation of industry standards such as ASHRAE/ACCA Standard 180-2008, Standard Practice for Inspection and Maintenance of Commercial Building HVAC Systems.
