, Simple Heating System Size:Washington State . , <br /> This heating svstem sizinq calculator is based on the Prescriotive Requirements of the 2012 Washington State Enerqv Code(WSECI 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 coolinct <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 ins�lation 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 Informafion <br /> Reykdal'1940 <br /> Heatinq Svstem Tvpe: O au ane�sY�rems �Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> Instructions ; �"'°� �"` �� y Design Temperature Difference(OT) 49 <br /> Everett Paine AFB � � <br /> dT=Indoor(/0 degiees)-Outdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> inscruct�ons Conditioned Floor Area(sq ft) ,r;r,,1,9401'' <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft} 9,3 18,042 <br /> Glazinq and Doors U-Factor X Area = UA <br /> InsWctions <br /> 0.30 335 100.35 <br /> Skvliqhts U-Factor X Area = UA <br /> Instructions 0.50 12 (0.00 <br /> Insulation <br /> Att�� U-Factor X Area = UA <br /> y"'' ��°'m"��. _a.�S.'/C�§_y,�.b`6". . <br /> Instructions R-a9 �� 0.026 1„528 50.13 <br /> Single Rafter or Joist Vaulted Ceilin��s,, ,,s 4 U-Factor X Area UA <br /> ; 1 W 1;.1�y ilu.t/,9�L�m" I�,.;�, u,arv�«„�i a. � <br /> Instructions ' ��R-value ��//� No SeleCtiOn -- <br /> Above Grade Walls�s�Fry�re�� U-Factor X Area UA <br /> Instructions ����`�� �"�`" �� <br /> tt-u mtermediate � 0.056 1j;555 87.08 <br /> Floors U-Factor X Area UA <br /> Instructions ' � `� "�' "'��""� ' " ��'� <br /> R-30 � 0.029 ��:1,940 56.26 <br /> Below Grade Walls�sea Fry�.e�� U-Factor X Area UA <br /> Instructions �� ��� ��� ��"`""����� � <br /> , <br /> w Select R-value .
