, Simple Heating System Size: Washington 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.
