�. . . . ��,bld�yq <br />Sim le Heatin S stem Size: Washin ton State ' f�� <br />P 9 Y J <br />This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton 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 coolina <br />loads. <br />The glazing (window) and door portion of this caiculator 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 />Piease fill out ail 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 />Unit El Townhome Poiygon 1Vorthwest <br />Silver lake Townhomes Alaina Robertson <br />Everett, Washin ton (425) 606-0005 <br />H@dtlllp SVSt@Ill TV{Je': O Forced Air Furnace Q Heat Pump <br />To see detailed instructions for each section, place your cursor on the word "Instructions". <br />Desiqn Temperature <br />�"`""`„1Of' - --------.---- ---- ---� - — Design Temperature Difference (�T) <br />Everett JC __ �`� AT = Indoor (70 deg�ees) - Outdoor Design Temp <br />�„s. �: - .� . <br />Area of Buildinq <br />Conditioned Floor Area <br />ans:E�;t:;io;:s Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />�rlt"-'�°'°"5 Average Ceiling Height (ft) <br />Glazinq and Doors <br />i.^,struc!ecrts <br />Insulation <br />Attic <br />_ _ _ _ __ <br />snstna::.on� -- --- — ,� <br />k R-49 � <br />t _ _" _ ..,;� o-Cf�l'��` - <br />Single Rafter or Joist Vaulted Ceilings <br />_. . _ _.__ __ ___. ___ _ <br />;ns,i is: iicn. � No Vaulted Celiinps In this pro)ect�_ ��,.,� <br />-.. � , . <br />v..y.:y::r�,o.� ' - <br />Above Grade Walls �s�F�aur�» <br />!��s.rur.tioris �_.___----------- _ --- <br />R-21 � : ; <br />� - <br />Floors <br />_ _.._. _ <br />Ins?�uctio;is -- " _ , I <br />j R30 �� <br />1�.., - ' <br />Below Grade Walls rSK Fieure �l <br />__ __ _ _ _.._ <br />In_,fru::tiatis . __.. __._ _. __ __._ � <br />� tro Oelow Grade Walls in tbls pro�ect. � <br />` _ — - - <br />Slab Below Grade rsee F�a�.e u <br />In=_eructicns _ _...._- .--- _- --_ _ .I <br />�No Slab 6elow Grade m this projec[ �' I <br />� — �'= n J � <br />Slab on Grade �see F�c�re n <br />�nstructicr�s ---- ------ --- I <br />R 10 Penmet2� � I <br />�� � � <br />.d _..
