Prescriptive Path - Single Family 2018 Washington State Energy Code-R 3 almple rteating system wze: trvasnington agate 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.
