'�Simale Heatina Svstem Size: Washinaton State <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 Information <br />Unit E3 Townhome Polygon Northwest <br />5ilver Lal<e Tovmhomes Alaina RoberCson <br />Everett, Washin ton (425) 606-0005 <br />HedilllQ SySte171 TVI�e: OO Forced Air Furnace Q Heat Pump <br />To see detailed instructions for each section, p/ace your cursor on the word "Insfructions". <br />Desiqn Temperature <br />�cu4ru�iior�s _. �__ —, Design Temperature Difference (�T) <br />k EVerelt JC �� � 4T = fndoor (70 degrees) - Ouldoor Design Temp <br />1....i-��,ii____'��3��� ...._.__,..�., ) <br />Area of Buildinq <br />Conditioned Floor Area <br />er,s�� uctions Conditioned Floor Area (sq ft) <br />Average Ceiling HeighY <br />if5L1 "��iO1J Average Ceiling Height (ft) <br />Glazinq and Doors <br />inskruc!ians <br />Insulation <br />Attic <br />I,�struc�ioz; — - j <br />� R-�i9 � j <br />Single Rafter or Joist VaWted Ceilings <br />fnsfratctsorrs ..-- � - -:_ ..._ � <br />� No Vaultetl Cellinps In this proJect <br />t -- — � _ ��� <br />Above Grade Walls �:ee Fre�re y� <br />Instructions , -- — � <br />� ��.
