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 lnfomration Contact Information <br /> Avaire Apartments Renovation-Laundry Conversion Casino Westmont Affordable Housing <br /> 824 Casino Rd, Corey Baldwin. <br /> Everett WA 98204 425454-8205 Ext:238 <br /> Heating System Type: O 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 /> Instructions -- -- - -- --- <br /> i• Everett x -, Design Temperature Difference(Al) 47 <br /> o AT=indoor(70 degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Instructions Conditioned Floor Area(sq ft) I 720 I <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) 17.81 5,580 <br /> Glazing and Doors U-Factor X Area = UA <br /> instructions ",,,,�,� • <br /> �� 0.250 60 15.00 <br /> Skylights U-Factor X Area = UA <br /> Instructions <br /> 0.50 0 — <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions " <br /> R-313 Advanced 0.026 I 720 I 18.72 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> Instructions -' -"- =- - - <br /> No Vaulted Ceilings in this project � <br /> r. ,, — - 0 <br /> Above Grade Walls(see Figure 1) U-Factor X Area UA <br /> Instructions -•-_. ____, <br /> _____ _-__ <br /> R 21 Intermediate wti <br /> 0.056 I 868 I 48.61 <br /> lk . <br /> Floors U-Factor X Area UA <br /> Instructions <br /> No Floors above urrcorWrborrad spaces — 0 <br /> Below Grade Walls(see Riede l) U-Factor X Area UA <br /> Instructions <br /> No Below Grade Walls in the project 0.028 <br /> Slab Below Grade rsee Figurer) F-Factor X Length UA <br /> Instructions <br /> No Slab Below Grade m thus project 0.303 I 112 I 33.94 <br /> Slab on Grade(see Fooure 1l F-Factor X Len•th UA <br /> Instructions ----- <br /> ft-10 Perimeter0.540 112 60.48 <br /> ..:vr^ ,r.c-vi -iis <br /> Location of Ducts <br /> Instructions <br /> No Ducts Duct Leakage Coefficient <br /> 1.00 <br /> Sum of UA 176.74 <br /> Envelope Heat Load 8,307 Btu/Hour <br /> Figure 1.
