Simple Heating System Size:Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerav Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinp loads onlv ACCA procedures for sizinct coolinq svstems should be used to determine coolina <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 /> Unit El Townhome Polygon Northwest <br /> Edipse lamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> H28tIf7Q SVSt@Rl T�/pB: �O Forced Air Wmace �Heat Fump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> �„s�r�,��;o„s _ ____ ___. _ - Design Temperature Difference(OT) 47 <br /> � Everett JC �� � pT=Indoor(70 degrees)-Outdoor Design Temp <br /> l <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> ins�ru�c�u��s Conditioned FloorArea(sq ft) 1,344 <br /> Average Ceiling Height Conditioned Volume <br /> instrucc�ons Average Ceiling Height(ft) 8.5 11,424 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions �.30 183 54.78 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions � �j� 0.026 591 15.37 <br /> � I R_49 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instruclions ,_...._.._____._..__.__._._.._------.—.----_.--�� i � <br /> � i No Vzulred Ceilings in this project. � <br /> l �..__._..._......_..___.___...._ ._ .� - <br /> Above Grade Walls�5ee Fr9�.�» U-Factor Area UA <br /> Instructions � ; "'''- '"'"�`�""" "— � � 0.056 413 23.13 <br /> R-21 <br /> � <br /> Floors U-Factor Area UA <br /> _ -- --- <br /> .___._ <br /> Instructions ' --" �I � 0.029 345 10.01 <br /> I I R-30 <br /> i y <br /> Below Grade Walfs�5ea Fry,,,�r� U-Factor Area UA <br /> Instnictions � �"� � <br /> � '�No Delow G ade Walls m lhis prqed � <br /> � . ... .......... ._. ._.. � <br /> _-..w,. _., .a..�. <br /> Slab Below Grede <br /> (see Figura 1J F-Factor Length UA <br /> ��,5����t���,5 � .._ . _-- - -.- — - I � <br /> I �No Slab Below Grade m this pro�ect � i <br /> � __. ._-.._ .._. ..___-_ _---'I � <br /> Slab on Grade�see F;9���I s F-Factor Length UA <br /> InsVuctiuns 4 IR-10Penmeter � �� 0.540 34 18.36 <br /> l -- - - --- � <br /> Location of Ducts <br /> Instructions __. _____ ____ ____ � � Duct Leakage Coefficient <br /> I ��Conditioned Space � � <br /> ` �.�� <br /> Sum of UA 121.64 <br /> Envelope Heat Load 5,717 Btu/Hour <br /> Fi ure 1. s�mofunxor <br /> Air Leakage Heat Load 5,799 Btu/Hour <br /> ��, VolumeX O.6X�TX.018 <br /> Ahove Grade Building Design Heat Load 11,516 Btu/Hour <br /> .��;i- ' AirLeakage+EnvelopeHeatLoss <br /> �'� Building and Duct Heat Load 11,516 Btu/Hour <br /> � Ducfs in unconditioned space:Sum o/6uilding Heat Loss X 1.10 <br /> Ducts in conddioned space:Sum of Building Heat Loss X 1 <br /> Maximum Heat Equipment Output 16,122 etu/Hour <br /> Building and Duct Heat Loss X 1.40(or Forced Air Fumace <br /> Building and Duct Heat Loss X i25 for Heat Pump <br /> �"+p .', � <br /> �� (07/01/13) <br /> �'� 'i. <br />
