Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriqtive Reauirements of the 2012 Washinqton State Enerav Code(WSECI and ACCA <br /> Manuals J and S This calculator will calculate heatina loads onlv ACCA procedures for sizina coolinq 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 /> Unit El Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> Heatinq Svstem Type: O Fo��ea a��w��ace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> i�,siructions ___ _..__...:._ _.._:.___. _:.<_._ . ....�_l � Design Temperature Difference(4T) 47 <br /> ( �Everett JC �I pT=Indoo�(70 degrees)-Outdoor Design Temp <br /> � _ <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> ioscructio�,5 Conditioned FloorArea(sq ft) 1,344 <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) 8.5 11,424 <br /> Glazina and Doors U-Factor X Area = UA <br /> Inslructions 0.30 183 54.78 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions �_ – � ' �I I 0.026 591 15.37 <br /> I_R_49 7,,,s'v <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions ������ -- - -�- ��-�� <br /> � 0 <br /> I �No Vaulted Ceilings in this pro�ect �� --- <br /> ` .___. _ � ___;.,.' <br /> Above Grade Walls�see F�s�re a� � _ _� _ U-Factor Area UA <br /> Instructions ; i � I 0.056 413 23.13 <br /> i R-21 j <br /> � -- _,...:: .-.---- ,.s..,.,,..��w..e;,:._ <br /> Floors U-Factor Area UA <br /> Instructions j "--`" � � 0.029 345 10.01 <br /> � �30 _J <br /> Below Grade Walls�see Fry�re�� III U-Factor Area UA <br /> Instructions � �..-_ ...-�--- -- �-- � � <br /> t i No Below Grade Walls m this pro�ect <br /> � --- --- <br /> Slab Below Grade�SeeFry��r� F-Factor Length UA <br /> Instructions ._. _-- -- — � I --- � <br /> I �No Slab Below Grade in this pro�ect J <br /> � . _..__ .....� ,.__.I <br /> Slab on Grade�see Frs���I !
