Simple Heating System Size: Washington State <br /> This heatina svstem sizina calculator is based on the Prescri�tive 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 /> Prc o�id I�liormaton Contact Information <br /> e-r�.E�- a,�,�� <br /> Plan 1875 <br /> Heatina Svstem Tvue: <br /> To see detailed instructions for each section,place your cur'sor on the word"Instructions". <br /> Desiqn Temperature <br /> instruc�ians Design Temperature Difference(4T) 49 <br /> Everett Paine AFB � I <br /> OT=lndoor(70 degrees)-Oufdoor Design Temp <br /> ti� �.w..�:.1. :�a..._ J <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> ir�scructions Conditioned Floor Area(sq ft) 1,875 <br /> Average Ceiling Height Conditioned Volume <br /> �rstr.3c:�o�,s Average Ceiling Height(ft) 8.5 15,938 <br /> Glazinq and Doors U-Factor x Area = UA <br /> Instr=�ctians 0.30 256 76.80 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> instructic;�s R�9 -� � 0.026 1,200 3120 <br /> �s i s�'- - __ .�� <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Inskruetians '—` � <br /> No Vaulted Ceilings in this project. � — <br /> Above Grade Walls�see Fry�.e�� U-Factor Area UA <br /> instruczians j 0.056 2,000 112.00 <br /> R-Z1 � � <br /> Floors U-Factor Area UA <br /> Irstru�tiorFs - ' 0.029 1,200 34.80 <br /> R-30 � � <br /> � . _ i <br /> Below Grade Walls fsee Fiyure�� U-Factor Area UA <br /> ins2rEactia;2s � <br /> ,No Below 6rade Walls in this project. � j f "-` <br /> - .:..��_.
