REVIEWED BLD2022-1276+Energy_Calculations+9.23.2022_9.18.55_AM+3125678Simple heating System Slze: wasnington State
This heating system sizing calculator is based on the Prescriptive Requirements of the 2018 Washington State Energy Code (WSEC) and ACCA Manuals
J and S. This tool will calculate heating loads only. ACCA procedures for sizing cooling systems should be used to determine cooling loads.
Please complete the green drop -downs and boxes that are applicable to your project. As you make selections in the drop -downs for each section, some
values will be calculated for you. If you do not see the selection you need in the drop -down options, please contact the WSU Energy Program at
energycode@energy.wsu.edu or (360) 956-2042 for assistance.
