Simple Heating System Size: Washington State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of the 2018 Washington State Energy Code(WSEC)and ACCA Manuals <br /> J and S.This tool will calculate heating loads only ACCA procedures for sizing cooling systems should be used to determine cooling loads- <br /> jPlease 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 <br /> 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 <br /> energycode@energy.wsu edu or(360)956-2042 for assistance <br /> Protect Information Contact Information <br /> A&P Holdings Marie Anderson @ Nash&Asso Architects <br /> 79th PI.NE,Granite Falls (425)242-7491 <br /> Q4/13/2021. <br /> He,_ �j System Type: O All othersystems rJ Haat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions" <br /> Design Temperature <br /> Instructions Design Temperature Difference(AT) 47 <br /> $ - ® AT=Indoor(70 degrees)-Outdoor Design Temp <br /> A.r•_?.
