Sir�ple Heating System Size: Wasllti�__::ton State __ <br /> This heating svstem sizinq calculator is based uii itie Prescriptive Requirements of the 2012 Washinqtc � - _te Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heating loads only ACCA procedures for sizinq coolinq svstems should be used fo determine coolinq <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 Confact Informafion <br /> Plan 1816 _ . •. _ , -. _ <br /> Heatinq Svstem Type: <br /> To see detailed instrucfions for each section,place your cursor on the word"lnstructions" <br /> Design Temperature <br /> �ns�ruc*ions r --_.=-=.----=-�--- ---- �---�-:-.
