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 /> Av i/fr A ►trrte'n Ren ` Mar't'i �rsio ?!"41i r �. casino Wesbmon Affo[ a gkfiousin " �. :s-,, <br /> 824`Cas io R r," �'-i`.,'.azo t" ftr*,' F r <br /> Etrei'ett'WA.8004: C ;s?.1 A T r r� '�c x 3 <br /> Heating System Type: O All Other Systans p Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word Instructions' <br /> Design Temperature <br /> Instructions "'° <br /> Everett]C Design Temperature Difference(Al) 47 <br /> ._... <br /> AT=Indoor(TO degrees)-Outdoor Design Temp <br /> Area of Building <br /> Conditioned Floor Area <br /> Instructions Conditioned Floor Area(sq ft) . k fk"::`p% <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) <br /> >Alfgzw n'B 5,580 <br /> Glazing and Doors U-Factor X Area = UA <br /> trtstructEarrs <br /> U-0.25 0.250 •,'."`%.!.1.&!---44':- <br /> r 15.00 <br /> Skylights <br /> U-Factor X Area = UA <br /> Instructions <br /> 0.50 r .:. — <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions � " _ . ,_ � � <br /> R-38sdvanc V-'.. 0.026 _ r >:x�. 18.72 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor X Area UA <br /> Instructions _ --v <br /> No Vaulted Ceilings in this project. <br /> Above Grade Walls(see Figurer) U-Factor X Area UA <br /> Instructions <br /> R-2r intermediate �. 0.056 ".. 48.61 <br /> Floors U-Factor X Area UA <br /> Instructions _ — <br /> M <br /> Below Grade Walls(seeFigtue 1) U-Factor X Area UA <br /> Instructions "" <br /> No t?efow Grade wails m this project. �: 0.0281-,,.. .‘.'s..-.51 <br /> es,-' <br /> Slab Below Grade(see Route 1; F-Factor X Length UA <br /> Instructions 0.303 <br /> d :d'I 33.94 <br /> Slab on Grade(see Ream 11F-Factor X Len th UA <br /> Instructions ' ` - _ . = <br /> R-10 Perimeter -- 0.540 : 60.48 <br /> Location of Ducts <br /> Instructionsr <br /> _..„ " "' Duct Leakage Coefficient <br /> No Duds V_. <br /> 1.00 <br /> Sum of UA 176.74 <br /> Envelope Heat Load 8,307 Btu/Hour <br /> Figure 1. sum ofUAXOT <br /> Air Leakage Heat Load 2,832 Btu/Hour <br /> Volume 06X0TX.018 <br /> Nwvecnde Building Design Heat Load 11,139 Btu/Hour <br /> —..
