Simple Heating System Size: Washington State <br /> This heatinq svstem 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 onlv ACCA procedures for sizinq coolinq svstems should be used to determine coolinq <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 E1 Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> Heatinq Svstem Tvpe: OO Fo��ed n��F�����e O Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> instru�cions _ ...... ._._.� 1{ Design Temperature Difference(OT) 47 <br /> l�,Evcrett 1C 'I q AT=Indoor(70 degrees)-Ou(door Design Temp <br /> ___.-----------___� <br /> Area of Building <br /> Conditioned Floor Area <br /> i°Si'�'��'0°5 Conditioned Floor Area(sq ft) 1,344 <br /> Average Ceiling Height Conditioned Vofume <br /> insv�cc�ons 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 �� + 0.026 591 15.37 <br /> � R-49 <br /> �. -- -- -- - .�9� <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instructions -. .....- __: ..._.. . ..__ --�— � � <br /> No Vaulted Ceilings m[his pro�ect ���I <br /> I .__ _._ __ .. <br /> ` ..._... _'_ _ _ <br /> Above Grade Walls�see F�y�.e�� � U-Factor Area UA <br /> Instructim�s � " -""" -'`"'-" "'- -"'�� � 0.056 413 23.13 <br /> � R 21 __ <br /> .�.J <br /> Floors U-Factor Area UA <br /> �nstructions � I R-3o � �� � 0.029 345 10.01 <br /> (, �__._ _..... _:� _-^r <br /> BQIOW GfBde WBIIS(see Figure 1) U-Factor Area UA <br /> Instructions � -._.. ...._ _..__. .. ...— � <br /> � No Below Grade Walls in this pro�ect � <br /> --- -- <br /> i ... .. ._._ __— - ..__ <br /> l ...
