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 Manuals <br /> J and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling loads. <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,some <br /> 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 Program at <br /> (360)956-2042 for assistance. <br /> Project information Contact ln(ormation <br /> Avaire Apartments Renovation-Laundry Conversion - Casino Westmont Affordable Housing <br /> 824 Casino Rd.- Corey Baldwin <br /> Everett WA 98204 425-454-8205 Ext 238 <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 /> Instructions - - <br /> lEverett x '..
