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 lnrbrmatron Contact information <br /> Avaire Apartments Renovation-laundry Conversion Casino Westmont Affordable Housing <br /> 824 Casino Rd. <br /> Corey Baldwin <br /> Everett WA 98204 425-454-8205 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 /> Design Temperature Difference(AT) 47 <br /> Everts[x - 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) <br /> 7.8I 5,580 <br /> Glazing and Doors U-Factor X Area = UA <br /> trtsfructloris -- _ <br /> U-025 0.250 I 60 I 15.00 <br /> Skylights U-Factor X Area = UA <br /> Instructions 0.50 <br /> - o I — <br /> Insulation <br /> Attic <br /> U-Factor X Area = UA <br /> Instructions <br /> R-38 Advanced w ; 0.026 I: 720 I 18.72 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> Instructions 1 - - �- --- <br /> i No VaulteI <br /> Ceilings m the project aw t. — a <br /> . <br /> Above Grade Wails(see Figure 1) U-Factor X Area UA <br /> Instructions ---------_---- .. <br /> R-211nterrned�ate ` 0.056 868 48.61 <br /> _ �r.. <br /> Floors <br /> U-Factor X Area UA <br /> Instructions <br /> No Floors above teioon(Lthnad spans — 0 <br /> Below Grade Walls&wargrue1) _ _ U-Factor X Area UA <br /> Instructions '-- <br /> 0 No Below Grade walls in this project. w` 0.028 <br /> Slab Below Grade(seeFk,ure n F-Factor X Length UA <br /> Instructions _»+ri.m..rara <br /> No Slab Belau Grade in ibis project. w, 0.303 112. 33.94 <br /> Slab on Grade(see Ftuure 11 F Factor X Length UA <br /> Instructions ' d <br /> k to Penmeter � `'. 0.540 I 112 I 60.48 <br /> Location of Ducts <br /> InstructionsFir — _ _-_..�. <br /> No acts Duct Leakage Coefficient <br /> 1.00 <br /> Sum of UA 176.74 <br /> Envelope Heat Load 8,307 Btu/Hour <br /> Figure 1.
