Simpl�,�Heating System Size: Wash = �n State <br /> Thys heatinq system sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerq�Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heatinq loads only ACCA procedures for sizinq cooling svstems should be used to determine coolinc� <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 2435 <br /> Heatinp Svstem Type: <br /> To see detailed insfructions for each section,p/ace your cursor on the word"Instructions". <br /> Desiqn Tempera�ure <br /> 3r32�iiC`.i0!t8 . . . � <br /> �. - --- - -- Design Temperature Difference(4T) 46 <br /> '��,'Lynnwoad � `$ pT=Indoor(70 degrees)-Oufdoor Design Temp <br /> `7�n�'R �'.` - - .-..�. <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> "'��'`"��"""�'� Conditioned FloorArea(sq ft) 2,435 <br /> Average Ceiling Height Conditioned Volume <br /> E°">tr''E�";"s Average Ceiling Height(ft) 8.5 20,698 <br /> Glazinq amd Doors U-Factor X Area = UA <br /> '�'����'"�s"���� 0.30 438 131.40 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> in��r«r.tic>n� ' � � -- � I 0.026 996 25.90 <br /> ��.:�R-49 ��;�� <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> €nstrEact;cns __ ----____._-. � <br /> L. 1.N"o Vaulted Ceilings in this project. g_� <br /> --- <br /> 'Vlii'WMIiiS�ilkii� <br /> Above Grade Walls�SeeF�y��ea� U-Factor Area UA <br /> !nseruc'�ar:s _ __ -- --__ - --__. ._------.— ____ 0.056 2,500 140.00 <br /> � I R-Zl �,��� <br /> r -,._ - <br /> Floors U-Factor Area UA <br /> E3iSYC42C;L1�i15; . .'-'—.__�.�.__._.__'_:.._"__"'___.__"_—_ <br /> �;�R-30 .y� 0.029 470 13.63 <br /> Below Grade Walls�see F�gure�� U-Factor Area UA <br /> r t�.r.i;.:,,; { � --- <br /> � � ¢� i No Below Grade Walls m this pro�ect � --- <br /> �16iRa __ _ -- - __ ,�_�� <br /> �lab BeloMr Grade/see F�yu.e�� �-Factor �—�eRg--th-7 UA <br /> li:SYiLif¢lO�'i5 � - _ -_. - . - - -�. • _" i 1 <br /> ��F,_�No Slab Below Grade in this project. �,,,,� L—J <br /> Slab on Grade�see F�y�.e t� F-Factor Length UA <br /> {tISqEE.!f,':,i7i"S . _ "'___.__. _..._........ ......_, . <br /> R-y i�R-lo Perimeter ��� 0.540 82 44.28 <br /> Location of Ducts <br /> ���}'"���'='��'� - -- -- - - M Duct Leakage Coefficient <br /> � ,j Unconditioned Space � <br /> °„� 1.10 <br /> Sum of UA 35521 <br /> Envelope Heat Load 16,339 Btu/Hour <br /> Flqure 1.
