Residential Heating and Cooling Load Calculation Requirements - Code Notes

The 2006 and 2009 International Energy Conservation Code require sizing calculations be performed on every home by referencing International Residential Code Section M1401.3. Section M1401.3 requires heating and cooling systems be sized to the Air Conditioning Contractors of America (ACCA) Manual J - Eighth Addition or other approved heating and cooling load calculations. The ACCA sizing methodology has sufficient built-in safety factors to accommodate most conditioning needs.
