a j <br /> 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 /> Gregory Schroeder Apt.#2 Les White Arc3ddesign <br /> 6524 Tyee Road 308-73rd.S.W.Everett,Washington 98203 <br /> Everett,Washington 98203 425-210-2935 <br /> Heating System Type: eAll Other Systems OHeat 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 Paine AFB <br /> AT=Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) 396 <br /> Average Ceiling Height Conditioned Volume <br /> Average Ceiling Height(ft) 7.0 2,772 <br /> Glazing and Doors U-Factor X Area = UA <br /> Instructions - - - - - - --- - - - — - -- - <br /> U-o.30 . 0.300 80 24.00 <br /> Skylights U-Factor X Area = UA <br /> 0.50 --- <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> -3 - -- -- -- -- -- <br /> R 38 Advanced � 0.026 396 10.30 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA �� <br /> Select R_Value _ - w No selection --- L <br /> i �p�jr; i— CD <br /> Above Grade Walls(see Figure 1) U-Factor X Area UA 6 1 1- N <br /> Select R-Value w l No selection 656 .1:1 © cc,U <br /> _J N (j.j L <br /> Floors U-Factor X Area UA '� ti > ) <br /> ----- --- ------------ ----- - — <br /> R-30 VJ 0.029 396 11A8 pa N l l.j(/) <br /> Below Grade Walls <br /> (see Figure l) U-Factor X Area UA �'� COILI <br /> No selection �j (� 0 I- <br /> Select R-value — — �.I pg <br /> a) <br /> Slab Below Grade(see Figure 1) F-Factor X Length UA ■�—a� U a <br /> i select conditioning w I No selection --- j <br /> Slab on Grade(see Figure 1) F-Factor X Length UA <br /> 'Select R Value -J No selection --- <br /> Location of Ducts <br /> Duct Leakage Coefficient <br /> No Ducts <br /> 1.00 <br /> Sum of UA 45.78 <br /> Envelope Heat Load 2,243 Btu/Hour <br /> Figure 1.
