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
energycode@energy.wsu.edu or (360) 956-2042 for assistance.
