V - pt�x� 1d � �,Z��t j � <br />Simplc. Heating System Size: Washington State � <br />This heatinq sVstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinaton State Enerqv Code (WSEC) and ACCA <br />Manuals J and S. This calculator will calculate heatinca loads onlv. ACCA procedures for sizina coolinq svstems should be used #o determine cooling <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 lnformafron Confact Informafion <br />Unit El Townhome Polygon Northwest <br />Silver LakeTownhomes Aiaina Rohertson <br />Everett, Washin on (425j 6D6-0005 <br />H2dtltlq SVSt2111 TVI�e: OO Forced Nr Furnace Q Heaf Pump <br />To see detailed instructions for each section, place your cursor on the word '7nstructions". <br />Desiqn Temperature <br />ir�,tr���c�or,s - - ---J,- � Design Temperature Difference (4T) <br />�` Everett )C � � � <br />..� 4T =lndoor (70 degreesJ - Outdoor Design Temp <br />Area of Buildinq <br />Conditioned Floor Area <br />ir�5�rn�c�o��5 Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />insrrucc�o�,s Average Csiling Height (ft) <br />Glazinq and Doors <br />I�structions <br />Insulation <br />Attic <br />_ . _ _ . ___ <br />Trrs�rit�ticns �J `"i � <br />�:.
