Associations Differ On Commercial Building Load Calculations

摘要

What do turf wars, battle lines, and tug of war have in common? They are all being mentioned by people involved in the creation of two rival commer-cial HVAC load calculation standards, one from the Air Conditioning Contractors of America (ACCA) and the other from the American Societyof Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE). ACCA first filed a Project Initiation Noti-fication System (PINS) form on Aug. 6,2004, for a commercial load procedure standard, but ACCA did not act on it because the organization believed that the upcoming ASHRAE standard would be open to Manual N and other commonly used procedures. ASHRAE Mowed with its PINS filing on Dec. 17, 2004, for Standard 183P, "Methods and Procedures for Performing Peak Cooling and Heating Load Calculations in Buildings Except Low-Rise Residential Buildings."
