f , . <br /> Simple Heating System Size: Washington State <br /> This heatinp svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heatinq loads only.ACCA procedures for sizinq coolinq svstems should be used to determine coolina <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 2012 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 lnformation <br /> Unit E1 Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> H@eYlllq SVSY@Ill TVpB: �O Forced Air Furnace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> i"`;�""t","'.
