Simple Heating System Size: Wa::::::::�ton State <br /> This heating svstem sizinq calculator is basea uii uie Prescriptive Requirements of the 2012 Washinq rate Energy Code(WSECI and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads only ACCA procedures for sizinq cooling svstems should be used to 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 applicabie 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 � Contacf Information <br /> .,�,,: ._> . � � � ��. . ...._ <br /> Pian 2435 <br /> Heatinq Svstem Tvpe: <br /> To see detailed insfructions for each section,place your cursor on the word"lnstructions". <br /> Desiyn Zemperature <br /> �nstr«ctions (• ----_------u- -=.-W-;:� Design Temperature Difference(OT) 46 <br /> y�Lynnwood '�;�Z- pT=lndoor(70 degrees)-Outdoor Design Temp � <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> '"���`�"�i°�45 Conditioned FloorArea(sq ft) `:` "2,d35 <br /> Average Ceiling Height Conditioned Volume <br /> fs:strur,eic�ns Average Ceiling Height(ft) ? 8.5 20,698 <br /> Glazing and Doors U-Factor X Area = UA <br /> �������t+4�� 0.30 ;.
