Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinctton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatina loads onlv ACCA procedures for sizinct 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 Eutension <br /> Program at(360)956-2042 for assistance. <br /> Project Information Contact lnformation <br /> Unit E3 Townhame Polygan Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> HBBtlllq$ySt@(Tl TVpB: 0 Forced Air Fumace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> instr��ct�ons __ _.. _ -- I Design Temperature Difference(4T) 47 <br /> ' 'Everett 1C _� J pr=lndoor(70 degrees)-Outdoor Design Temp <br /> 1`— <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> inscruc�ions Conditioned FloorArea(sq ft) 1,560 <br /> Average Ceiling Height Conditioned Volume <br /> instruccions 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 /> InsVuctlons ._.._- --- . — - <br /> R-a9 . 0.026 688 17.89 <br /> ��— -.— ---- — � <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions ._.-. . ...._._ ......._..___ ....._._. .. � <br /> I No Vaulted Ceilings in this pro�ec[ _ .__� : --" <br /> ��_ �—f� <br /> A6ove Grade Walfs�SeeFr9�,��� U-Factor Area UA <br /> __ _ <br /> .._.� _.__.._ <br /> InsVuctions � <br /> .. _- � , 0.056 1,801 100.86 <br /> � ,R-21 <br /> L <br /> Floors U-Factor Area UA <br /> _– - <br /> Instructions � i__. __.::_ ._____. . _..___._ _.... <br /> � �R-3o .� � 0.029 430 12.47 <br /> ...�,w..0 <br /> Below Grade Walls�5ee F;9�.��� U-Factor Area UA <br /> Instructions i " --�-- -..:— —�-- � <br /> No�elow Grade Walls m this pro�ec[ � --- <br /> � .__.._ __. ._ _... .,_:��.rrecy:�� <br /> Slab Below Grade(see Fiyure�) F-Factor Length UA <br /> Instruc[ions � ..—.... . . --- --� --- � <br /> No Slab Below Grade in this pro�ect � <br /> � __.. .. ..___._ _..— . <br /> Slab on Grade�seeFr9,..��� F-Factor Length UA <br /> Instructions .... ...... —._... . _ .. <br /> I �R-1oPenmeter � 0.540 75 40.50 <br /> � _ _._. t_.. � 1 <br /> Location of Ducts <br /> inscruccions _. _..._ _ ____ _ .
