REVIEWED BLD2022-0015+HEATING+1.6.2022_8.27.48_AM+2605981Simple Heating System Size: Washington State REVIEWED
This heating system sizing calculator is based on the Prescriptive Requirements of the 2018 Washin on State Energy Code e4efin and ACCA
Manuals J and S. This tool will calculate heating loads only. ACCA procedures for sizing cooling syst sssshould be used to din ne cooling loads. n
Please complete the green drop -downs and boxes that are applicable to your project. As you makes IeR�yr� ih the dQFnEle���R�jplh� obi
values will be calculated for you. If you do not see the selection you need in the drop -down options, p ase contact the WSU Energy Program at
