Simple Heating System Size: Washington State <br /> Thisheatina svstem sizin4�alculator is based on the Prescriotive Requirements of the 2012 Washinaton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heatina loads onlv.ACCA procedures for sizina coolina svstems should be used to determine coolina <br /> 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 <br /> 0.30. The 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, <br /> some 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 E�ension <br /> Program at(360)956-2042 for assistance. <br /> Project fnformation �� Contact Information <br /> Plan 1875 <br /> Heatina Svstem Tvpe: <br /> To see detailed instructions for each section,place your cursor on the wo��l"Instructions". <br /> Desiqn Temperature <br /> instrucc,ons ---- -- - --- -- Design Temperature Difference(4T) 49 <br /> � ��.Everett Paine AFB � <br /> _ pT=lndoor(70 degrees)-Ouldoor Design Temp <br /> -- -����s--�- =a.�tisr�i <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> Instructians Conditioned Floor Area(sq ft) 1,875� <br /> Averege Ceiling Height Conditioned Volume <br /> ��,str�ace3c�ns Average Ceiling Height(ft) 8.5 15,938 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0.30 256 76.80 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> insTruccicns i l R�9 - � � 0.026 1,200 31.20 <br /> Y:�.n....�i.�_..1.� _ �"�J <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions j .__ � <br /> No Vaulted Ceilings in this project. � � <br /> - --- 1 <br /> Above G�ade Walls(see Figure�) U-Factor Area UA <br /> Instruc:fc�ns � 0.056 2,000 112.00 <br /> �R-21 � <br /> `dY�wV+P+Y" -11 — � <br /> Floors U-Factor Area UA <br /> �nseruG�;ar�s + 0.029 1,200 34.80 <br /> R-30 � <br /> '.r-�`�- <br /> Below G�ade Walls(see Fiyure�) U-Factor Area UA <br /> instructians _._ � � <br /> No Below Grade Walls in this project. � ; <br /> L � _�=� <br /> Slab Below Grade(seeFigure�) F-Factor Length UA <br /> Instriictians �Y'j -•- � <br /> No Slab Below Grade in this project. � <br /> L... � <br /> Slab on Grade�see Fry�re�� F-Factor Le� UA <br /> lnstritctio�ts � •-- <br /> i No Slab on Grade in this project. � <br /> -- ..�. <br /> Location of Ducts <br /> �nstrucsicsns _ - Duct Leakage Coefficient <br /> Unconditioned Space � <br /> _ - --� 1.10 <br /> Sum of UA 254.80 <br /> Envelope Heat Load 12,485 Btu/Hour <br /> Figure 1.
