� �I• p��x, btd�' �,�,to/ t `tV <br />� Simple Heating System Size: Washington State <br />This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Ener4v Code (WSEC) and ACCA <br />Manuals J and S. This calculator wiil calculate heatinq loads onlv. ACCA procedures for sizinq coolina svstems should be used to determine coolinq <br />loads. <br />The glazing (window) and door portion of this caiculator 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 />Projecf Informafion Contact Information <br />Unit El Townhome Polygon Northwest <br />Sllver Cake Townhames Alaina Rohertson <br />Everett, Washin ton (425} 606-0005 <br />Heatinq System Tvpe: O Fo��d w� F�ma�e Q Heat Pump <br />To see detailed instructions for each section, place your cursor on the word '7nstructions". <br />Design Temperature <br />:"� t; `�` "O�:' Design Temperature Difference (�T) <br />� EverO[t JC � ; , � �T = Indoor (70 degrees) - Ouldaor Design Temp <br />Area of Buildinq <br />Conditioned Floor Area <br />"''r,-���:Oi1= Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />�"SfruCt'�y"= Average Ceiling Height (ft) <br />Glazinq and Doo�s <br />ii1S,� IICiIoitS <br />Insulation <br />Attic <br />_ _ <br />r,str�,ct,.�� .. ____ _____ � , <br />F � R-49 � .�. <br />�c �'.���:< - _ — - �� _�*_� <br />Singte Rafter or Joist Vaulted Ceilings ^ <br />_ _ _ _ _ __ <br />L:s`.rucc;o�s � _._ _ <br />E �o Vaul[ed Ceihnqs in this projecC. ��� <br />Above Grade Walls �sre F�eare �� <br />l�,si�uctior5s � ___ �. <br />R 21:_.. ,,.. .. ._ . � �?:�;;<� <br />Floors <br />__ . _ <br />Instruci;�ns j '— — � <br />R-30 � E <br />E � - - .a <br />Below Grade Walls r5K Fr9ure �1 <br />Instructions - -_ — --- I <br />� no eeiow Grade waus m mis pro�ect. •( <br />- _ , <br />Slab Below Grade r:� Fiaure n <br />i615YRIL{ICI15 '-- — ` -'� ` I <br />t No Slab Below Grade m th�s pro�ect �< I <br />�r, 1 <br />Slab on Grade �see Fr�u2 �i G <br />l�164fucivon3 . __-- - —_.___..�.._.�__� ..__._ _ ;:.
