REVIEWED BLD-BLD2021-1694+WSEC-HEATING+12.14.2021_4.58.25_PM+2573082REVIEWED BY CITY OF EDMONDS € BUILDING DEPARTMENT BLD2021-1694 RECEIVED Dec 20 2021 CITY — EDMONDS Simple Heating System Size. Washington State DEVELOPMENT SERVICES RTMENT 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.
