REVIEWED+Energy_Calculations+7.18.2021_7.54.58_PM+2306865RECEIVED Dec 13 2021 Simple Heating System Size: Washington State CITY OF EDMONDS ERVICI This heating system sizing calculator is based on the Prescriptive Requirements of the 2018 Washington State Energy Code (WSEC) and ACCA DFPARTM NT 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.
