Simple Heating System Size: Washington State <br /> This heatina svstem sizina calculator is based on the Prescriotive Reauirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads onlv ACCA orocedures 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 /> Projecf Information Contact Information <br /> Unit E3 Townhome Polygon Northwest <br /> Eclipse lamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> �"�@8tlftQ$YSt@I'Tl T�/p@: �Porced Air Furnace Q Heat Pump <br /> To see detailed instructions for each section,place your curso�on the word"Instructions". <br /> Desiqn Temperature <br /> inscrucc�ons ' _.____._.__.._____._.________.:_�_-___� � Design Temperature Difference(c1T) 47 <br /> � <br /> Gverett 1C � <br /> __ OT=Indoor(70 degrees)-Outdoor Design Temp <br /> 'L'__ _ e - — <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> inscrucc�ons Conditioned FloorArea(sq ft) 1,560 <br /> Average Ceiling Height Conditioned Volume <br /> Instructions 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 /> Instructions �— -- -�-�-- � — <br /> I 'R-a� .� � 0.026 688 17.89 <br /> � _.. -- -- —... <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions --"-� �"- ` � <br /> 1I No Vaulted Ceilings m this pro�ect �� I --- <br /> ��--- — .�.,- .. . _ .-a�...�.::�::J <br /> Above Grade Walls�SoeFry���� U-Factor Area UA <br /> Instructions ..__. .--_:. ._._.._...,. ._....:___ ._.. <br /> I ,,R-zi .� I 0.056 1,801 100.86 <br /> i . <br /> Floors U-Factor Area UA <br /> ----- <br /> Instructions • ,_.. --�•-,-�--�•-,---..._ <br /> � LR_30 � 0.029 430 12.47 <br /> ----� <br /> Below Grade Walls�see F;g�.�» U-Factor Area UA <br /> Instructions ��--- --__ .-__.. ._..:_ I <br /> � I No 6elow Grade Walls m this pro�ed � "' <br /> � ._.. ____ ' __.—u- � J <br /> Slab Below Grade�see F�yure�� F-Factor Length UA <br /> InsVuctions I --�- --' � <br /> No Slab Below Grade in this pro�ect � <br /> l -- �---- --� :. -- . <br /> Slab on Grade�SeeFr9��» F-Factor Length UA <br /> Insvuctions — � 0.540 75 40.50 <br /> I �R-10 Penmeter !� � <br /> � ... . __. ..._._.. <br /> Location of Ducts <br /> instruccions , .__ __-_ _. -�'� Duct Leakage Coefficient <br /> � �Condrtioned Space � <br /> 1.00 <br /> 5um of UA 243.98 <br /> Envelope Heat Load 11,467 Btu/Hour <br /> Fiqure 1. s�mofuAxor <br /> Air Leakage Heat Load 6,731 Btu/Hour <br /> �, VolumeX 0.6XOTX.018 <br /> Above Grade Building Design Heat Load 18,198 Btu/Hour <br /> � ������� �� ��"�����- � - Air Leakage+Envelope Heat Loss <br /> eeiow�«ae , Building and Duct Heat Load 18,198 Btu/Hour <br /> Ducfs in unconditioned space:Sum of Building Heat Loss X 1J0 <br /> Ducts in conddioned space:Sum of Building Heat Loss X 1 <br /> Maximum Heat Equipment Output 25,477 Btu!Hour <br /> Building and Duct Heat Loss X 1.40 fo�Fo/ced Air Fumace <br /> Building and Duct Heat Loss X 125 Po�Heat Pump <br /> � � <br /> i �. ! � (07/01/13J <br />
