October 16, 2015

The Air Conditioning Contractors of America Educational Institute (ACCA-EI) Standards Task Team (STT) announces an American National Standards Institute (ANSI) public review period for its BSR/ACCA 2 Manual J-201x, “Residential Load Calculation” as a revised industry standard. The 45 day public review period started on October 16, 2015 with a comment deadline of November 30, 2015.

The revised standard details the requirements for producing a residential load calculation per the CLF/CLTD method contained in Manual J, 8th Edition. The provision of the standard apply to any dwelling unit that has its own heating-cooling-ventilating system and equipment, and its own exhaust air system(s). This includes:

  • ​Single family detached structures, duplex structures, and triplex structures;
  • Single family attached structures (row house or town house);
  • Dwelling units in multi-family attached structures (condo and apartment units); and
  • Energy efficient homes.

The revised standard has been divided into two portions: normative and informative. Parts N (Normative Requirements) and 4 (Tables) contain the minimum requirements for conducting a residential load calculations. Informative Parts 1, 2, 3, and 5 contain additional explanation, details, and examples that clarify the normative requirements.
