Simple Heating System Size: Washington State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 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 /> 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 /> Sisk Residence:Addition Vernon E Dusseau Jr <br /> 1410 Hollow Dale PL 6619 132nd Ave NE,PMB 242 <br /> Everett,WA 98204 Kirkland,WA 98033 <br /> Heating System Type: ® All Other Systems 0 Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Design Temperature <br /> Design Temperature Difference(AT) 49 <br /> Everett Pame AFB <br /> .. { AT,-Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) 1,736 <br /> Average Ceiling Height Conditioned Volume <br /> instructions Average Ceiling Height(ft) 8.1 14,051 <br /> Glazing and Doors U-Factor X Area = UA <br /> — <br /> u.o.3o 0.300 273 81.90 <br /> Skylights U-Factor X Area = UA <br /> 0.50 0 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions 12-19 0.026 924 24.02 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> instructions R-38 Vented 0.027 812 21.92 <br /> Above Grade Walls(seeFigure1) U-Factor X Area UA <br /> 5-21 Intermediate v <br /> 0.056 1,148 64.29 <br /> Floors U-Factor X Area UA <br /> 0.025 1,736 43.40 <br /> R-38 <br /> Below Grade Walls(see Figure n U-Factor X Area UA <br /> Select R-value No selection <br /> Slab Below Grade(see Figure 1) F-Factor X Length UA <br /> • Select card boning i No selection <br /> Slab on Grade(see Figure 1) F-Factor XLe� UA <br /> Select R-Value V No selection <br /> Location of Ducts <br /> Duct Leakage Coefficient <br /> No Ducts V <br /> 1.00 <br /> Sum of UA 235.54 <br /> Envelope Heat Load 11,541 Btu/Hour <br /> Figure 1.
