9/27/2016 (IHINDS-JORDAN-35-Heat Sizing code specs final=ids <br /> Simple Heating System Size: Washinon State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 Washington State Energy Code(WSEC)and ACCA Manuals J <br /> and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling 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 0.30. <br /> 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,some <br /> 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 Program at(360) <br /> 956-2042 for assistance. <br /> Project Information Contact Information <br /> JORDAN LEE HINDS <br /> Heating System Type: <br /> To see detailed instructions for each section,place your cursor on the viord'Instructions". <br /> Design Temperature <br /> Instructions Design Temperature Difference(AT) 49 <br /> AT=Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Instructions Conditioned Floor Area(sq ft) 76 <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) 8.0 608 <br /> Glazing and Doors U-Factor X Area = UA <br /> Instructions <br /> 0.30 63 18.90 <br /> Skylights U-Factor X Area = UA <br /> Instructions 0.50 — <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions 0.026 76 1.98 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> Instructions No selection --- <br /> Above Grade Walls(see Figure 1) U-Factor X Area UA <br /> Instructions 0.056 208 11.65 <br /> Floors U-Factor X Area UA <br /> Instructions 0.029 76 2.20 <br /> Below Grade Walls(see Figure 1) U-Factor X Area UA <br /> Instructions No selection <br /> Slab Below Grade(see Figure 1) F-Factor X Length UA <br /> Instructions No selection <br /> Slab on Grade(see Figure 1) F-Factor X Length UA <br /> Instructions No selection <br /> Location of Ducts <br /> Instructions Duct Leakage Coefficient <br /> 1.10 <br /> Sum of UA 34.73 <br /> Envelope Heat Load 1,702 Btu/Hour <br /> Sum of UAXAT <br /> Air Leakage Heat Load 322 Btu/Hour <br /> IA, <br /> VolumeX 0.6XATX.018 <br /> Building Design Heat Load 2,023 Btu/Hour <br /> Air Leakage+Envelope Heat Loss <br /> Building and Duct Heat Load 2,226 Btu/Hour <br /> Ducts in unconditioned space:Sum of Building Heat Loss X 1.10 <br /> Ducts in conditioned space:Sum of Building Heat Loss X 1 <br /> https://dm2-excel.officeapps.live.com/x/_layouts/d printview.asp O&NoAuth=1&sessionld=12.4eeed32a3f731.A79.1.V24.1091641 rEMA%2BN7%2BLYnizM FYM 14.... <br />
