ARLINGTON, Va. - The Air Conditioning Contractors of America (ACCA) announced vigorous opposition to a proposed American National Standards Institute (ANSI) Standard 183P, "Procedures for Performing Peak Heating and Cooling Calculations in Buildings Except Low-Rise Residential Buildings" on commercial load calculation offered by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE).
ACCA is encouraging contractors to review the document and provide comments during the 45-day public review period. ACCA has reviewed the proposed standard and determined that there are significant flaws in its application to small commercial buildings. This includes procedures and approaches that may be acceptable for large buildings but are not fully appropriate or practical for small buildings.
