Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinaton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads onlv ACCA procedures for sizinq coolina 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 applicabie 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,p�ease call the WSU Energy Extension <br /> Program at(360)956-2042 for assistance. <br /> Project Information Contacf Information <br /> Unit E1 Townhome Polygon Northwest <br /> Edipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> H@8tlflQ SVSY.BfII TVpe: OO Forced Air Furnace 0 Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> Ins[ruc[ions � _.._._. __._.___ ...._._. - ._.... � � Design Temperature Difference(OT) 47 <br /> � EverettJC � <br /> 4T=Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> instruccions Conditioned Floor Area(sq ft) 1,344 <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) 8.5 11,424 <br /> Glazinq and DOors U-Factor X Area = UA <br /> Instructions 0.30 183 54.78 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions I R ay � �� 0.026 591 15.37 <br /> I _ __ ___.. _-- <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions -.."....- �. . ...-�- ----�-�- 1 � <br /> _�. <br /> � No Vaulted Ceilings m this pro�ect. � --- <br /> l .�____ -.— � <br /> Above Grade Walls�SeeF;s�rer� U-Factor Area UA <br /> Instructions i �R-Zt - ----_:�.._._��..._.....� ] 0.056 413 23.13 <br /> l - :,e..w..� <br /> Floors U-Factor Area UA <br /> - _ _ <br /> Instructians I i - -._ ___.. _._.._ � � 0.029 345 10.01 <br /> � �RdO � <br /> Below Grade Walfs�see F;9�re» U-Factor Area UA <br /> Instructions ' I � � � <br /> � .No.8elow Grade Walls m this pio�ect <br /> � --- --- <br /> � ...... .., .. � <br /> . u.r .m,w r.�.�w. <br /> Slab Below Grade�SeaF�s�.�+1 F-Factor Length UA <br /> Instivctions �-__ _._.- -- -- -���. .� �� <br /> !
