Simple Heating System Size: Washington State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of the 2012 Washington State Energy Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling <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 try 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 42064 PAUL BUSTARD <br /> 425-876-6551 <br /> Heating System Type: , Forced Air Furnace C Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Design Temperature <br /> instructions i ... -- — Design Temperature Difference(AT) 49 <br /> Everett Paine AFB "" S7=indocr(70degrees)•Du:dog r Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Instructions Conditioned Floor Area(sq ft) 2,064 <br /> Average Ceiling Height Conditioned Volume <br /> instructions Average Ceiling Height(ft) 8.0 16.512 <br /> Glazing and Doors U-Factor X Area = UA <br /> Instructions. 0.30 280 84.00 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions <br /> R 49 T j 0.026 1,320'' 34.32 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> instructions _...._.
