Simple Heating System Size: Washington State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 Washington State Energy Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling <br /> loads. <br /> The glazing(window)and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of <br /> 0.30. The incorporated insulation requirements are the minimum prescriptive amounts specified by the 2015 WSEC. <br /> Please fill out all of the green drop-downs and boxes that are applicable to your project.As you make selections in the drop-downs for each section, <br /> some values will be calculated for you. If you do not see the selection you need in the drop-down options,please call the WSU Energy Extension <br /> Program at(360)956-2042 for assistance. <br /> Project Information Contact Information <br /> Balbir Singh Harold French <br /> 2212 Pine Street 21620 84th Ave.S.Suite 200 <br /> Everett,WA 98201 Kent,WA 98032 <br /> Heating System Type: O All Other Systems 0 Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Design Temperature <br /> Everett JC Design Temperature Difference(AT) 47 <br /> _._,..,.
