Simple Heating System Size:Washington State <br /> This heating system sizing calculator is based on the Prescnotive Requirements of the 2012 Washington State Enerav Code IWSECI and ACOA Manuals J and S This <br /> calculator will calculate heating loads only.ACCA procedures for sizina cooling systems should be used to determine cooling loads <br /> The glazing(window)and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of 0.30. The <br /> incorporated insulation requirements are the minimum prescriptive amounts specified by the 2012 WSEC. <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 values will be <br /> calculated for you.If you do not see the selection you need in the drop-doom options,please call the WSU Energy Extension Program al(360)956-2042 for assistance. <br /> !'r jectlnf niation Contact Information <br /> DIAZ RESIDENCE LUES F STALER <br /> 2802 Victor PL. <br /> 23003 55th Ave <br /> Everett,WA98201 Mountlake Terrace,WA 98043 <br /> Beatina System Tvoe' <br /> To see detailed instructions for each section,place your cursor on the word 7nstruct,ons <br /> Deakin Temperature <br /> Design Temperature Difference(AT) 47.0 <br /> r�..�•�..o _•� b;?ua�rvra✓ er=mdo«Uo d sreeal-oumoor assign r r'v <br /> Area of Building <br /> Conditioned Floor Area <br /> 3 v,- Conditioned Floor Area(sq ft) 2791") <br /> • <br /> • <br /> • <br /> Average Ceiling Conditioned Volume <br /> Height <br /> • <br /> A• verage Ceiling Height(ft) 8.01 22,328 <br /> Glazina and Doors <br /> U-Factor X Area = uA <br /> - 0.30 I 364 i 109.05 <br /> insulation <br /> Attic U-Faetor X Area = UA <br /> y33 �3 =_. <br /> lo, ,,t;u:: r a rR ® w -_ 0.026 1664 1726 <br /> Area UA <br /> Single Rafter or Joist Vaulted C!!!1!,,,,,, ,_ U-Factor <br /> Seri ,i'3nr;s 4 a� d 7 a 0.627 I 416 I 11.23 I <br /> I <br /> _ = Above Grade Walls raae Moura r/ U-Factor Area UA I <br /> - 0.056 ( 1,960 I 109.76 <br /> Floors U-Factor Area UA <br /> :n :v,:, 0.029 <br /> x 150 435 <br /> Below Grade Walls tree ravure r/ U-Factor Area UA <br /> 1g 0.042 1,038 43.60 <br /> Slab Below Grader r-tg q F-Factor Loogth UA <br /> ._. ✓.c,,,,.� ,. 0.570 132 75.24 <br /> Slab on Grade A pl 0 F-Factor Length UA <br /> iocvoct,vs g &3 -- 0.360 1 132 1 47.52 <br /> ,,r .t »..✓:,. ✓ ,cam„ ,M,,....... ;n <br /> Location of Ducts <br /> • '✓ '� - Duct Leakage Coefficient i <br /> ' ,.Yr a!✓ 1.00 <br /> 418.01 <br /> Sum of UA <br /> Envelope Heat Load 19,647 Btu/Hour <br /> Figure 1.
