ACCA believes that this standard is essential for contractors, engineers, and design professionals in establishing heat gain/loss estimates for small/light commercial applications, which typically utilize cooling equipment that has a nominal capacity of 25 tons or less.
"Commercial buildings of three stories and less differ considerably from the residential homes whose load calculations are determined by ACCA's Manual J, which is an ANSI standard," said Paul T. Stalknecht, ACCA president & chief executive officer.
"At the same time, they also differ considerably from larger commercial building applications. This standard, an improvement on ACCA's industry-accepted Manual N, provides the accurate estimates required to ensure occupant comfort and safety."
