KISSIMMEE, FL — The Air Conditioning Contractors of America (ACCA) held a press conference at its 34th Annual Conference to provide a “sneak preview” briefing on Version 8 of Manual J, the industry standard for residential load calculation.
Manual J contains calculations for heat gain and heat loss for residential structures. The new version is its first major revision in 15 years. The updated Version 8 was a collaborative effort spearheaded by Hank Rutkowski, ACCA technical consultant, and Glenn Friedman, a technical consultant for Taylor Engineering, Alameda, CA.
