R Sim�le Heating System Size: Washington State <br /> This heatina svstem sizina calculator is based on the Prescriptive Reauirements of the 2012 Washinaton State Enerav Code(WSEC)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 2267 <br /> H@8t1f19 SVSt@fil TVpe: OO Forced Air Fumace �Heat Pump <br /> To see detailed instructions for each section,p/ace your cursor on the word"lnstructions". <br /> Desiqn Temperature <br /> [nstraeticns Design Temperature Difference(oT) 49 <br /> Everett P�ne AFB � � OT=Indoor(70 degreesJ-Outdoor Design Temp <br /> 1 <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> �"�zT„��"��'� Conditioned Floor Area(sq ft) 2,267� <br /> Average Ceiling Height Conditioned Volume <br /> tratre�e,�io��a Average Ceiling Height(ft) 8.5 19,270 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instr�:ceir�r:s 0.30 349 104.70 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> �nstre�ctiona � 0.026 1,370 35.62 <br /> R-49 � <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> lnatructians � --- � <br /> No Vaulted Ceilings in this project. � <br /> Above Grade Walls ISeeFry�re�� U-Factor Area UA <br /> Instructir�as "--- 0.056 2,500 140.00 <br /> R-zi � l <br /> �� <br /> Floors U-Factor Area UA <br /> Inszructinns — - - 0.029 1,370 3973 <br /> R-3D � <br /> �r�_ i <br /> Below Grade Walls/5ee F�y�re�� U-Factor Area UA <br /> 3ristrsawtians — � --- <br /> No Below Grade Walls in this project. � <br /> - — � <br /> Slab Below Grade/5ee Fry�re�� F-Factor !�Len'g�th UA <br /> 141StCCiGL1C71S - ' __ i I <br /> No Slab Below Grade in this project. _ I L—� <br /> J <br /> Slab on Grade�SeeFry�re�� F-Factor Length UA <br /> 1i1.;tYU�$Ip31S "' � <br /> No Slab on Gr-+ade in this project. � I <br /> J <br /> Location of Ducts <br /> Instrucx,ans Duct Leakage Coefficient <br /> Unconditioned Space J _ _� •—� I <br /> �� 1.10 <br /> Sum of UA 320.05 <br /> Envelope Heat Load 15,682 etu/Hour <br /> Fi ure 1. s�moiunxor <br /> ry``,je�„���� Air Leakage Heat Load 10,197 etu/Hour <br /> _s:..............._.._,.,.�"'�.
