• <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 /> MAVERICK REMODEL SIALER DESIGN LLC <br /> 6601 BEVERLY BLVD 16008 MOTOR PL <br /> EVERETT,WA 98206 LYNNWOOD,WA 98087 <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 /> InstructionsIII <br /> - -- - - -- Design Temperature Difference(AT) 49 <br /> Everett Paine AB - ...^ <br /> AT=Indoor(70 degrees)-Outdoor Design Temp <br /> • <br /> Area of Building <br /> Conditioned Floor Area <br /> Instructions Conditioned Floor Area(sq ft) 832 <br /> Average Ceiling Height Conditioned Volume <br /> Average Ceiling Height(ft) 6.8 5,658 <br /> Glazing.and Doors U-Factor X Area = UA <br /> Instructions <br /> 0.30 24 7.14 <br /> Skylights U-Factor X Area = UA <br /> Instructions 0.50 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions SelectR-value ,.j No selection --- <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> Instructions SelectR-Val. �� No selection --- <br /> Above Grade Walls(see Future 1) U-Factor X Area UA <br /> Instructions Se1MR-Value No selection --- <br /> 01 <br /> Floors U-Factor X Area UA <br /> Instructions See R.V a No selection <br /> Below Grade Walls(see Figure 1) U-Factor X Area UA <br /> Instructions OR-21 Interior v 0.042 765 32.13 <br /> Slab Below Grade(seeFipurel) F-Factor X Length UA <br /> Instructions select conditioningNO selection <br /> Slab on Grade(see Figure 1) F-Factor X Len <br /> UA <br /> L•lsh uclions'. -..— —.. <br /> Select R-Vdl V No selection --- <br /> �. <br /> Location of Ducts <br /> Instructions Duct Leakage Coefficient <br /> Conditioned Space <br /> 1.00 <br /> Sum of UA 39.27 <br /> Envelope Heat Load 1,924 Btu/Hour <br /> Figure 1.
