�im IA Heatin System Size: Washington State <br /> This heatina svstem sizina calculator is based on the Prescriotive Reauirements ofthe 2012 Washinaton State Enerqv Code(WSEC1 and ACCA <br /> Manuals J and S.This calculator will calculate heatina loads onlv.ACCA orocedures 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 Extension <br /> Program at(360)956-2042 for assistance. <br /> Project Information Contact Information <br /> Plan 2203 <br /> H08tI11Q SVSt0f11 TV{7e': O Forced Air Fumace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desian Temoerature <br /> knstruccions Design Temperature Difference(4T) 49 <br /> Everett Paine AFB � 1 pT=Indoor(70 degrees)-Outdoor Design Temp <br /> ''`� - -- - - --- '-- ---- - <br /> Area of Buildinp <br /> Conditioned Floor Area <br /> inseg�uctsons Conditioned FloorArea(sq ft) 2,203 <br /> Average Ceiling Height Conditioned Volume <br /> �r,strcactions Average Ceiling Height(ft) 8.5 18,726 <br /> Glazina and Doors U-Factor X Area = UA <br /> Instruc2ions 0.30 345 103.50 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> instruc�ians R�9 � ! 0.026 1,320 34.32 <br /> , - -��- � <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> In5truC*'t4n5 No VaWted Ceilings in this project. � � � <br /> � <br /> Above Grade Walls�see F�y�.e�� U-Factor Area UA <br /> insa-uvt�ons — 0.056 � 2,370 132.72 <br /> a-u � � <br /> � .��. <br /> Floors U-Factor Area UA <br /> �nstructians 0.029 1,320 38.28 <br /> R-30 � � <br /> - ' •/ <br /> Below Grade Walls/see Fry�re�� U-Factor Area UA <br /> Instructians ♦ --- � "_ <br /> No Below Grade Walls in this project. <br /> �.. - - - - -��-� <br /> Slab Below Grade/see Fiqure�� F-Factor Le� UA <br /> liistrt�ctions No Slab Below Grade in this project. � <br /> I <br /> Y - ' <br /> Slab on Grade Isee F��re�� F-Factor Le� UA <br /> I�tstruetloiis - _ � + <br /> No Slab on Grade in this projett. <br /> . - -' — - c - -.�.-, .,I <br /> Location of Ducts <br /> �������"+��� Duct Leakage Coefficient <br /> 1 `Unwnditioned Space _ _ � � 1.10 <br /> Sum of UA 308.82 <br /> Envelope Heat Load 15,132 Btu/Hour <br /> Fi ufe 1.
