Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton 5tate Enerqv Code(WSEC1 and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads onlv ACCA qrocedures 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 lnformation <br /> Uni[E3 Townhome Polygon Narthwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> Heatinq Svstem Type: OO Fo�ced n��w��a�e Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> inscruc�ions ; . ______...._...._�_.��.r.—�_.-_-.� � Design Temperature Difference(OT) 47 <br /> � '�[verett JC <br /> `�. � `� �T=Indoor(70 degrees)-Duldoor Design Temp <br /> .._'—__— _ ' _ <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> Instructions Conditioned FloorArea(sq ft) 1,560 <br /> Average Ceiling Height Conditioned Volume <br /> inscruccions Average Ceiling Height(ft) 8.5 13,260 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0.30 241 72.27 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions — — �J I 0.026 688 17.89 <br /> R-49 � <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> InsUuctions i ..-_ ... ..._._ __-' --- � <br /> �^No Vaulted Ceilings m this pro�ect � <br /> ��, . — ___— —--I <br /> Above Grade Walls�SeeFr9�,��� U-Factor Area UA <br /> Instructions � ___ ... .::.._:. - ::.__..�.� —.___....._... ._. <br /> R-zi .� I 0.056 1,801 100.86 <br /> � <br /> Floors U-Factor Area UA <br /> h,sVuctions �...... �-.:_:.-.::_ - -._._ -:..: _..... <br /> I I R-3a . 0.029 430 12.47 <br /> � -- — � , <br /> Below Grade Walls�see F�y�.��� U-Factor Area UA <br /> �OS��U�����,5 � _�:_- �.-__. .__..._ _ --,..
