ASHRAE Seeks Comments on Improvements to 90.1

Reported by ACHR News: "The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has announced that public input to help shape the technical requirements in Standard 90.1 is being sought through 21 proposed addenda, which could become part of the 2010 version of the standard.

ANSI/ASHRAE/IESNA Standard 90.1-2007, Energy Standard for Buildings Except Low-Rise Residential Buildings, provides minimum requirements for the energy-efficient design of buildings except low-rise residential buildings. The proposed addenda cover a range of topic areas, including daylighting, air leakage, EER and IEER values, and requirements for VRF air conditioners and heat pumps."
