• <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 /> 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 2015 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 /> Tsymbalyuk Residence.ADU Tatyana Shadyrya <br /> 6406 Highland Dr 22420 6th 131 W,Bethel,WA <br /> Everett,WA 98203 Archstudio"Y.Shadyrya" <br /> Heating System Type: °All Other Systems Heat Ramp <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 /> caeca v:.+"-un <br /> AT=indoor GM degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) ( 797 <br /> Average Ceiling Height Conditioned Volume <br /> Average Ceiling Height(ft) I 8.01 6,376 <br /> Glazing and Doors U-Factor X Area = UA <br /> 0.30 137 41.10 <br /> Skylights U-Factor X Area = UA <br /> 0.50 0 — <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> R< V . 0.026 1,000 1 26.00 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> mvC.rtA 0.027 I 797 21.52 <br /> Above Grade Walls(see Figare 1/ U-Factor X Area UA <br /> R-:,o->,.,ter. 0.056 789 44.18 <br /> Floors U-Factor X Area UA <br /> R e 0.029 797 23.11 <br /> Below Grade Walls(see ROWS 1/ —.. ._ U-Factor X Area UA <br /> rider Gad.11',h rt tMs on [ _ 0 — <br /> 1 <br /> .Giiil�p�ilfi.G1t1Y1i�ilflli(f4m�L'111WM�Yki�r� <br /> Slab Below Grade(see Rime t/ F-Factor X Len. t UA <br /> ;1b Slab 9c1P.,G,,d,m li.pnciKt.
