Simple Heating System Size: Washington State <br /> This heatinq system sizinq calculator is based on the Prescriotive Requirements of the 2012 Washington State Enerqy Code(WSEC)and ACCA <br /> Manuals J and S.This calculator will calculate heating loads only.ACCA procedures for sizinq cooling systems 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 E�ension <br /> Program at(360)956-2042 for assistance. <br /> Project Information � Contact Information <br /> Plan 2128 <br /> Heatinq System Tvpe: <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> � �����0�' �`��� - ------� � � � Design Temperature Difference(oT) 49 <br /> Everett Pame AFB � .3 <br /> � �T=Indoo�(70 degrees)-Outdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> ��°""��'�'�"b�`� Conditioned FloorArea(sq ft) 2,12$ <br /> Average Ceiling Height Conditioned Volume <br /> •�_�°� • �°� Average Ceiling Height(ft) 8.5 18,088 <br /> Glazinq and Doors U-Factor X Area = UA <br /> _�:�'°"`��'� 0.30 423 126.90 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> _. _ . _ , <br /> r� :r;r,4ie:;s R�9 . � 0.026 1,356 35.26 <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> __ _._.... _._ __� � <br /> .I���'ft^YI�.t'a <br /> No Vaulted Ceilings in this projed.
