Simple Heating System Size: Washington State <br /> This heatinq system sizinp calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads oniv ACCA procedures for sizinq coolinq systems should be used to determine coolinq <br /> loads. <br /> The giazing(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 /> Unit E1 Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> Heatinq Svstem Tvpe: OO Fo��ed a��F���a�e �Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> inscru�cions _.__,_ ...,_: Design Temperature Difference(�T) 47 <br /> � .Everett 1C _ _ � ' dT=Indoor(70 degrees)-Oufdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Fioor Area <br /> inscr�c��ons Conditioned Floor Area(sq ft) 1,344 <br /> Average Ceiling Height Conditioned Volume <br /> inscructions Average Ceiling Height(ft) 8.5 11,424 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0.30 183 54.78 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions _.__ . ..._. _.._. .- — <br /> I 'R d� - - - _!_I 0.026 591 15.37 <br /> � ..._� <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions � ...... ..,..-. ..-- _.... —� --- � <br /> No Vaulted Ceilings in this pro�ect �I <br /> ......_ ._._. ._.._ ._ .., <br /> .. _..:"',:� <br /> Above Grade Walls�5ee Fr9�.e�) U-Factor Area UA <br /> Instructions i ' - ` ---- "�"'-""-'�� l 0.056 413 23.13 <br /> R-Z� <br /> � ____ .._—__. _ ..._�.J <br /> Floors U-Factor Area UA <br /> Instructions � I R-3o ' "��" �I � 0.029 345 10.01 <br /> � - w— .��s� <br /> _. ..�. <br /> Below Grade Walls(see Fi9ure�) U-Factor Area UA <br /> -- _-- _._... — � <br /> 6,struc[ions , �i --- --- <br /> � No B I e Grade_Walls in this pro�ec[_ � <br /> Slab Below Grade�SeeF,9��e+� ' F-Factor Length UA <br /> Instructions _._.. .. ....._ _.._._ ..
