Simple Heating System Size: Washin ton State <br /> This heatinq svstem sizina calculator is based on the Prescriptive Recauirements of the 2012 Washinaton State Enerqy Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads onlv ACCA procedures for sizinq cooling systems 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 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 Information <br /> Plan 2006 <br /> Heatinp Svstem Tvpe: O Forced Air Furnace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on fhe word"Instructions". <br /> Desiqn Temperature <br /> E`'���"b�°°"� Design Temperature Difference(4T) 49 <br /> Everett Paine AFB � � <br /> � :,, �.;�, �T=Indoor(70 degrees)-Oufdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> '�'��'��'r°"��'`� Conditioned Floor Area(sq ft) 2,006 <br /> Average Ceiling Height Conditioned Volume <br /> �"`"£"`"'`;"`� Average Ceiling Height(ft) 8.5 17,051 <br /> Glazinq and Doors U-Factor X Area = UA <br /> €""�"�``°'�' 0.30 334 100.05 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> �'''���'�`'`"� Ray . � 0.026 1,431 37.21 <br /> ��:.c:..; :_...... - <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> (r�s;ruCt�c>nv � 9 � ` � <br /> � ...
