Simple heating System Size: 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.
