� <br /> Simple Heatin S stem Size: Washin ton State <br /> This heatin9 system sizin9 calculator is based on the Prescriotive Reauirements of the 2012 Washin9ton State Enerov Code(WSECI and ACCA <br /> Manuals J and S.This calculator will calculate heatinn loads onlv.ACCA orocedures for sizino coolina svstems should be used to determme coolino <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 /> Pro�ecf Jnlormation Contact lnlormation <br /> Plan 2314 <br /> HQBtIflQ SVStQ111 TVD@' OO Forced Air Fumace 0 Heat Pump <br /> To see detailed instructions lo�each section,place your cursor on the woid"Instructions". <br /> Desi4n Temperature <br /> Marysville � Design Temperature Difference(aT) 47 <br /> i AT=lndoor(70 degrees)-Outdoor Design Temp <br /> . <br /> Area of Buildina <br /> Conditioned Floor Area <br /> inscructions Conditioned Floor Area(sq ft) � 2,319 <br /> Average Ceiling Height Conditioned Volume <br /> inssrucs;ans Average Ceiling Height(ft) 1 8 5� 19,712 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0 30 340 102.00 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> �nstruc¢inns R�9 -- — _ � j 0.026 1,500 39 00 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> No Vaulted Ceilings in this proJed. � 1 "�' i_ _ 1 <br /> Above Grade Walls/sea Fx�ure�� U-Factor Area UA <br /> R-zl � 0.056 2.450 137.20 <br /> � , <br /> Fioors U-Factor Area UA <br /> Ins,ructions 0.029 1.500 I 43.50 <br /> l R-30 � J <br /> Below Grade Walls�see Fi9�re�� U-Factor Area UA <br /> No Below Grade Walls fn this pruJect� � � '-- � — J ��� <br /> 1 <br /> Slab Below Grade�see F�yu�e�� F-Factor Lon th UA <br /> No Slab Below Grade in this proJect. � �� <br /> L —----- ' <br /> Slab on Grade�saeF�y�re�� F-Factor Longth UA <br /> i <br /> No Slab on Grade in this proJed. � � � <br /> l__ _'�'... -_ --_"_J <br /> Location of Ducts <br /> Duct Leakage Coefficient <br /> Unconditioned Sp,xe � <br /> �--- -�---�-- — - .- ••- - �_..
