Simple Heating System Size: Washington State <br /> This heatina svstem sizina calculator is based on the Prescriotive Reauirements of the 2012 Washinaton State Enerav 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 1690 <br /> H@8tIf1Q SVSt@fll TVqe: �O Forced Air Furnace O Heat Pump <br /> To see detailed instructions for each section,Place your cursor on the word"Instnictions". <br /> Desiqn Temqerature <br /> Instructions ---- - -- Design Temperature Difference(c�T) 49 <br /> Everett Paine AFB � pT=Indoor(70 degrees)-Outdooi Design Temp <br /> .:..r. <br /> Area of Buildinp <br /> Conditioned Floor Area <br /> �nsgructions Conditioned Floor Area(sq ft) �� <br /> Average Ceiling Height Conditioned Volume <br /> �a,s;ruce3ons Average Ceiling Height(ft) 8.5 14,365 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0.30 269 80.70 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Ins�ruc?ians R�9 � s 0.026 1,000 26.00 <br /> t _.__ - 1 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> �llS�i';1C�30lI5 <br /> No Vaulted Ceilings in this project. � � "— <br /> �.- ) <br /> Above Grade Walls�see Frg�re» U-Factor Area UA <br /> ITtSiE';1C21Ct15 0.056 2,000 112.00 <br /> R-21 .� <br /> .._,�.,,.. - <br /> Floors U-Factor Area UA <br /> Ilt54ftdC�1GFTFS 0.029 1,000 29.00 <br /> R-30 � � <br /> Below Grade Walls�5ee Fry�re» U-Factor Area UA <br /> i�:Sft'uc:ions —_ '� � <br /> No Below Grede Walls in this project. � �— --- <br /> - _ - v;u�til(�Li:..� <br /> Slab Below Grade�5ee Fry�re�� F-Factor Length UA <br /> (�istructions —`_ ` --- � <br /> No Slab Below Grade in this project. 1 <br /> — Ra <br /> Slab on Grade�seeFiyure t1 F-FaFtor Le� UA <br /> ��istruetloz�s � 1 <br /> No Slab on Grade in this project. <br /> L <br /> Location of Ducts <br /> Ins�ructsons Duct Leakage Coefficient <br /> Unconditloned Space � ' <br /> -. .�. - -- - - 1.10 <br /> Sum of UA 247.70 <br /> Envelope Heat Load 12,137 Btu/Hour <br /> Fi ure 1. sumoruaxer <br /> p�^��...
