Sirnple Heating System Size: Wasllltli�ton State <br /> � Thi;>heatinq system sizinq calculator is based on the Prescriptive Repuirements of the 2012 Washinqton 5tate Enerqy Code�WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatin4 loads only ACCA procedures for sizinq coolinq svstems should be used to determine coolinq <br /> loacis. <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 2012 WSEC. <br /> Ple<�se 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 /> sorrie 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 /> Plan 1816 <br /> Heatinq Svstem Tvpe: <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> DG'SIQII�Ett1p0�8tU1'@ <br /> instr�ac4;ors ____ ______ _ _ _ ___.
