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 /> Hlamazda Residence.House adition Tatyana Shadyrya <br /> 9105 10th PL W 22420 6th Pi W,Bathe',WA <br /> Everett,WA 98204 Archstudio"YShadyrya" <br /> Heating System Type: ®Au Other Sri Otleat Pump <br /> To see detailed instructions for each section,place your cursor on the word Instructions" <br /> Design Temperature <br /> ti Design Temperature Difference(AT) 47 <br /> Everett JC --- -- -- w 11 AT=Indoor(70 <br /> t Hae aK. degrees) 00,-Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) 2,553 <br /> Average Ceiling Height Conditioned Volume <br /> Average Ceiling Height(ft) 8.0 20,424 <br /> Glazing and Doors U-Factor X Area = UA <br /> Instructions <br /> 0.30 355 106.50 <br /> Skylights U-Factor X Area = UA <br /> Instructions 0.50 0 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> In�tnr:aio"=, R49 ..._..- � 0.026 1,412 36.71 <br /> •Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> !in ctIons No Vaulted Ceilings in this project 847 <br /> Above Grade Walls(see Figurer) U-Factor X Area UA <br /> ist:,:;a:.)
