What this is, and is not
Residential heating and cooling load estimate following the ACCA Manual J 8th edition procedure. Design weather derived from published station data. This software is not ACCA-approved. First-pass estimate for review by a qualified designer. Where a licensed Manual J table was not available, the factor was derived and the derivation and its expected divergence are stated in the report.
