Sim le Heating System Size:Washington State <br /> This heating system sizing calculator is based on the Prescriptive Requirements of'the 2018 Washington State Energy Code(WSEC)and <br /> ACCA Manuals J and S.This tool will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine <br /> cooling loads. <br /> Please complete the green drop-downs and boxes that are applicable to your project.As you make selections in the drop-downs for each <br /> section,some values will be calculated for you.If you do not see the selection you need in the drop-down options,please contact the WSU <br /> Energy Program at energycode@energy.wsu.edu or(360)956-2042 for assistance. <br /> Project Information Contact Information <br /> Bement Addition RVJ Permit Consulting roniacobson6`. ail,coIT <br /> 1613 Orca View Ln 17223 174th Ave SE 206-510-5931 <br /> Everett,Wa.98203-1671 Renton,Wa.98058 <br /> To see detailed instructions for each section,place your cursor on the wont"Instructions" <br /> Design Temperature Difference(AT) 49 <br /> AT=Indoor(70 degrees)-Outdoor Design imp <br /> Conditioned Floor Area <br /> Conditioned Floor Area(sq ft) [ 416 <br /> Average Ceiling Height Conditioned Volume <br /> rion= Average Ceiling Height(ft) L 8.0 3,328 <br /> Glazing and Dor U-Factor X Area = IJA <br /> Instructions <br /> .28 103 213.70 <br /> Skylights IJ-Factor X Area = IJA <br /> Instructions 0.50 Insulation <br /> Attic IJ-Factor X Area = IJA <br /> Instructions .027 416 11.23 <br /> Single Rafter or Joist Vaulted Collings IJ-Factor X Area IJA <br /> `_t;" No selection -- <br /> Above Grade Walls(as.Figure 1) IJ-Factor X Area IJA <br /> .057 377 21.46 <br /> Floors 11-Factor X Area UA <br /> No selection -- <br /> Below Grade Walls(s..Figur.I) 1J-Factor X Area IJA <br /> No selection -- <br /> Slab Below Grade(se.new.v 1,-Factor X Length IJA <br /> No selection -- <br /> Slab on Grade(as.Figure 1) F-Factor X Length IJA <br /> Instruction, No selection -- <br /> Location of Our <br /> Instructions Duct Leakage Coefficient <br /> 1.10 <br /> Sum of UA 61.39 <br /> Envelope Heat Load 3,008 Btu/Hour <br /> Figure t.
