Simple Heating System Size: Washington State <br /> This heatinq svstem sizina 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 heatin4 loads onlv ACCA orocedures for sizina 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 ha�e 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 E3 Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> HB8YIf1Q SVSt@fTl TVPe: OO Forced Air Furnace 0 Heal Pump <br /> To see detailed instructions for each section,p/ace your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> i�,�.tr���c�ons I � __. _.. __._ __�__... .. ._,.� I Design Temperature Difference(�T) 47 <br /> [verett 1C � I <br /> _ _, _ � oT=Indoor(70 deqreesJ-Outdoor Design Temp <br /> �-.__—..,----=. .. _.._. �... ... .. . . .�. <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> ins�ruccions 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 /> h�svuctions 0.30 241 72.27 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> In>tructir�ns � ;R—n� -- - -- �� 0.026 688 17.89 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions I ._..._ __.. ._____...._. — -__. . �l � <br /> � �No Vaulted Ceilings m this pro�ect _ � Y! --- <br /> � -- - - ; 3 <br /> Above Grade Walls�sae Fr9�,��1 U-Factor Area UA <br /> ___. _. <br /> In,tructions '� . - _..._._..�:. ��.._ ......:.._. .._.._..� � <br /> R_zi �� 0.056 1,801 100.86 <br /> � ..a <br /> Floors U-Factor Area UA <br /> _ --- -... <br /> Instructions � I_._ . ..._.._ - . .,��_ . .__... � � <br /> R-30 . 0.029 430 12.47 <br /> �___ �=i.�,:.�i <br /> Below Grade Walls�SeeFr9�,�» U-Factor Area UA <br /> Instructions -_. --- .._- .. �- � <br /> No Below Grade Walls m this pro�ec[ � <br /> l. ____. ._'_ ._." _..... � <br /> Slab Below Grade�see Fry�.�r� F-Factor Length UA <br /> Instructions ( -�-- � -- . .__..- _.__ ...�...� --- � <br /> I No Slab Below Grade m this pro�ect � <br /> Slab on Grade�SeeF;y�,�» F-Factor Length UA <br /> Instructions ..__---------.�.---------- <br /> I !R-10 Perimeter � � 0.540 75 40.50 <br /> � ! _,_� __--�--,,.:,:. <br /> Location of Ducts <br /> i�,�x��cc�ons ___ __�% � Duct Leakage Coefficient <br /> I ,�Condihoned Space � <br /> � 1.00 <br /> Sum of UA 243.98 <br /> Envelope Heat Load 11,467 Btu/Hour <br /> Fiaure 1. s�morunxor <br /> ��� Air Leakage Heat Load 6,731 Btu/Hour <br /> � VolumeX 0.6X�TX.018 <br /> c nbo�e��aae BuildingDesignHeatLoad 18,198 BtulHour <br /> �.
