, �irriple Heating System Size. Was ;;�ton State <br /> This heatinq system sizing calcufator is basea on tne Prescriptive Requirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This caiculator will calculate heatinq loads only 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/nformafion � Contacf/nformation <br /> ... - <br /> Plan 1816 <br /> Heatinq System Type: <br /> To see detailed instructions for each section,place your cursor on the word"Instructions"_ <br /> Desiqn Temperature <br /> �ns�ructians ��------- ----- ----- w----�-,-�� Design Temperature Difference(4T) 46 <br /> � L nn._ . . _.�. ...._.. . . <br /> �y waod �} `� pT=Indoor(70 degrees)-Outdoor Design 7emp <br /> Area of Buildinq <br /> Conditioned FloorArea <br /> (s€sYructions Conditioned Floor Area(sq ft) -�. �� ��� 1,816��� <br /> Average Ceiling Height Conditioned Volume <br /> (stsfruetio�ts Average Ceiling Height(ft) ��l��.n,...�,,,��..�-;$���,� 15,436 <br /> Glazinq anJ Doors U-Factor X Area = !�A <br /> tnstructions 0.30 ��i5> 73.50 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> lnsieucYi�ns � R-49 �`—` �'' OA26 '94T. 24.47 <br /> ��iiAfliR�ii._.. ,. :' <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Insin,�c�iens ...�. ...,.;.�w<,�.._....W.�:. �,...,. <br /> '�� No Vaulted Ceilings m this project. ���F' --- E.._. :: �� � <br /> Above Grade Walls�see Fi9�re�� U-Factor Area UA <br /> tnstructio�s ""` - - `` 0.056 -'`�;100 117.60 <br /> R-21 . . . `.. <br /> Floors U-Factor Area UA <br /> Instructians y�r R-30 - - - � .� 0.029 ;20.Qis 5.80 <br /> Below Grade Walls�seeF;9�re» U-Factor Area UA <br /> �3752CLIG'�36tZS qs''--. . .; . _. _ . . ... , . �.�--"--''", � <br /> �No Below G2de Walls in this pmject.
