Simple Heating System Size: Washington State <br /> This heatinq svstem sizinp calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerpv Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heatinq loads only.ACCA procedures for sizinq coolinq 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 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 lnformation <br /> Unit E3 Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-770D <br /> H08t1(1Q SYStEfTI T�/EJO: OO Forced Air Fumace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the wo�d"Instructions". <br /> Desiqn Temperature <br /> instructions -::.. ... .....-".: -.-�-�- - -� Design Temperature Difference(4T) 47 <br /> � , ...,.. _I� � <br /> I �'i Everett JC AT=Indoor(70 degrees)-Outdoor Design Temp <br /> I.r..�:�a.'�^T-. � . . . . <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> i�,str�cno�,s Conditioned Floor Area(sq ft) 1,560 <br /> Average Ceiling Height Conditioned Volume <br /> mstruccions Average Ceiling Height(ft) 8.5 13,260 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0.30 241 72.27 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Insiructions ---"� -����� — <br /> j R a� -- F I dV l 0.026 688 17.89 <br /> t - - -� d <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions t -.- .-__... .___ . .__.._ � <br /> I No_Vaulted Ceilings in this pro�ect �I � � <br /> 4 -- <br /> Above Grade Walls�see Fry��e�� U-Factor Area UA <br /> �nstructions i R z � l 0.056 1,801 100.86 <br /> ; _.__.._.._---- --- � i <br /> w - <br /> Floors U-Factor Area UA <br /> -- . ___._. <br /> Instructions ��-� '�-�- � �—" `�" <br /> i I R 30 � 0.029 430 12.47 <br /> � ___ _ __ . <br /> B2IOW GfBCIQ W8II5(see Figure 1J U-Factor Area UA <br /> Instructions ...- _____ ..____ . :_ _.� � <br /> �� No Below Grade Walls in this pro�ect � <br /> _._. ___ . __ " -�— <br /> Slab Below Grade�se�Fry�re r� F-Factor �Length I UA <br /> Instruc[inns I ---- � ���� —I i I � <br /> ` l No Slab Below Grade in this pro�ec[ � ..9 �—� <br /> � ......... ----- '-_..-- ----- -- �..J <br /> Slab on Grade�See Fry�.e i� F-Factor Length UA <br /> histructions ; I_R_�0 Penmeter_ __��� __�I J 0.540 75 40.50 <br /> 1 � <br /> Location of Ducts <br /> instruceo�,s _..._ .�� ---.- � Duct Leakage Coefficient <br /> f I Conditioned Space �--I� ,�.00 <br /> t -�.- <br /> Sum of UA 243.98 <br /> Envelope Heat Load 11,467 Btu/Hour <br /> FIqUfE 1.
