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 Manuals <br /> J and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling 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,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 <br /> (360)956-2042 for assistance. <br /> Project Information Contact Information <br /> Garage Remodel Greenwave Property Investment,LLC <br /> 3927 Friday Ave: <br /> Everett,WA 98201 <br /> Heating System Type: OO 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 /> Design Temperature Difference(ST) 49 <br /> Everett Paine AFB • -;_ ST=Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) 454 <br /> Average Ceiling Height Conditioned Volume <br /> Average Ceiling Height(ft) 11.5 5,221 <br /> Glazing and Doors U-Factor X Area = UA <br /> u o tc •l 0.300 64 19.20 <br /> Skylights U-Factor X Area = UA <br /> .....,... 0.50 --- <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> stru ttonu No selection <br /> Select R-Value <br /> v�mss„ <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> Select R Value • No selection --- <br /> e <br /> Above Grade Walls(see Figure 1) U-Factor X Area UA <br /> R-21 Intermediate •1"".,, <br /> 0.056 992 55.55 <br /> Floors U-Factor X Area UA <br /> • No Floors above unconditioned spaces. • <br /> Below Grade Walls(see Figure 1) U-Factor X Area UA <br /> select R-value •"E <br /> No selection <br /> Slab Below Grade(see Figure 11 F-Factor X Length UA <br /> Select conditioning No selection <br /> Slab on Grade(see Figure 11 F-Factor X Len.th UA <br /> structfons 0.540 50 27.00 <br /> 5-10 Perimeter • <br /> Location of Ducts <br /> Duct Leakage Coefficient <br /> Select Location of Ducts • ' <br /> Sum of UA 101.75 <br /> Envelope Heat Load 4,986 Btu/Hour <br /> Figure 1.
