Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinp loads onlv.ACCA procedures for sizinq coolinq systems shouid 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 In(ormation <br /> Unit E3 Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> H@2tIf1Q SVSt@(T7 T\/p2: OO Forced Air Fumace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"lnstructions". <br /> Desiqn Temperature <br /> insc�uc�ions _ _ .,.._____ _... _.._ ._ � Design Temperature Difference(4T) 47 <br /> `�.EverettlC <br /> �.________ �I� .� pT=Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> i�,scr��caons Conditioned Floor Area(sq ft) 1,560 <br /> Average Ceiling Height Conditioned Volume <br /> insc�ucc�ons 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 /> � .R-49 __ ...�� �.�26 688 17.89 <br /> � _— '— — <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions � ._ ._.... .. ____ _..___— _..._, � <br /> Ii No Vaulted Ceilings in this pro�ect ����. � --- <br /> Above Grade Walls�see Fry��e�� U-Factor Area UA <br /> _-- _. __ <br /> Instructions - - --' --'----- '"-----'� � 0.056 1,801 100.86 <br /> R-2� � <br /> Floors U-Factor Area UA <br /> lostructions . -- :- --" 0.029 430 12.47 <br /> � IR30 � <br /> � .... _:_ _ ..__. ._ <br /> Below Grade Walls�see F;y�re t� U-Factor Area UA <br /> Ins(ruccions -... .—_.. __.._ ._.__:_. _.. � <br /> No Belo Grade Walls m this pro�ec[ � - <br /> ` ......._ ..._._._. __..._ _.. _._'—' <br /> Slab Below Grade�5ee Fry�re�� F-Factor Length UA <br /> Instructions i, __.. ._........ ....__. .. . .-1 � <br /> � i No Slab Below Grade in this pro�ect <br /> � --' <br /> t �--- — �-- ---- —_ <br /> 51ab on Grade�5ee Fry�.e i� F-Factor Length UA <br /> hutructions �I I 0.540 75 40.50 <br /> i �R-10 Penmeter I <br /> � ---- ._..__.__. __.. _ .. ---�' J <br /> Location of Ducts <br /> i�,str���c�ons _._ 1 Duct Leakage Coefficient <br /> � Londrtioned Space _ � J �.�� <br /> t <br /> Sum of UA 243.98 <br /> Envelope Heat Load 11,467 Btu/Hour <br /> Fiqure 1 SumofUAXOT <br /> Air Leakage Heat Load 6,731 Btu/Hour <br /> �i'���� VolumeX O.6X4TX.018 <br /> -aeo�e��aae Building Design Heat Load 18,198 Btu/Hour <br /> ��;• Air Leakage+Envelope Heat Loss <br /> Building and Duct Heat Load 18,198 Btu!Hour <br /> Ducts in unconditioned space:Sum ol Huilding Heal Loss X 1.10 <br /> Ducts in conddioned space:Sum ol8uilding Heaf Loss X 1 <br /> Maximum Heat Equipment Output 25,477 Btu/Hour <br /> 8uilding and Duct Heaf Loss X 1.40/or Forced Air Fumace <br /> Building and Duct Heat Loss X 1.25/or Heat Pump <br /> (07/01/13) t �/. <br /> I I ' <br />
