. � � ��' �d � � � <br />Sim le Heatin S stem Size: Washin ton State � ' ��� <br />p 9 Y 9 <br />This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinaton State Enerav Code (WSECI and ACCA <br />Manuals J and S. This calculator will calculate heatinq loads onlv. ACCA procedures for sizinq coolina svstems should be used to determine coolina <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 fiil 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 op6ons, please call the WSU Energy Extension <br />Program at (360) 956-2042 for assistance. <br />Project lnformation Contact Information <br />Unit El Townhome Polygon Northwest <br />Silver LakeTownhomes Alaina Robertson <br />Everett, Washin ton (425j 606-0005 <br />H@8tlllQ SySt@fTl TVpe: �O Forced Air Fumace Q Heat Pump <br />To see detailed instructions for each section, place your cursor on the word "Instructions". <br />Desiqn Temperature <br />�"`��' "�t1O�y Design Temperature Difference (4T) <br />Everett JC � � pT = Indoor(70 degreesJ - Outdoor Design Temp <br />E,:� - z - - <br />Area of Buildinp <br />Conditioned Floor Area <br />i,si�t;vu�;,-� Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />�n5trua�o„� Average Ceiling Height (ft) <br />Glazinq and Doors <br />instri�ctians <br />Insulation <br />Attic <br />Ins`nicf�or,s � � ;_;; <br />� R-49 � <br />.:.,f.i�= a.4-'m .w4t4$i ��:$'wx °514LSu Bm � `Jo <br />Single Rafter or Joist Vaulted Ceilings <br />9ns2n�cz;ons E - - _ _ � , <br />M1�o��Vaulted Cellin9s In this proJe[t <br />_S��} <br />Above Grade Walls �:re F�9�re rI <br />Instc'ucficr�s — - - -- — � <br />� R 21 , ,,. _ � , <br />�.ez�.._�+��.�a _.�.a:�::��',r`. <br />Floors <br />__ _ __ _ __ ___ _ _ <br />Insi;uctions � - -- <br />R-30 � - <br />�.�--r: , ��.� „_.:.;�, _�:,..s.�,t: �-:`_y �..., .�:,. <br />Below Grade Walls �:� FrH�re 1� <br />_ _.._ _ _ <br />;ns4rucfions __ _.-__._�. <br />�o Below Grade Walls m thls pro�ecc � t <br />�� -- .: =1*-1*;ra•-,,,��,,;h . -�=n ..,...,d.a..iG�" <br />�� <br />Slab Below Grade rsee Fio�re n <br />Instructions - _ -- ---- -- <br />� No Slab Below Grade In this pro)ect ��< <br />%, .,�•* — - - <br />Slab on Grade �see F�a�re a� <br />Insiructicns — - - -- ----- <br />ti i R-10 Penmeter � �,>� <br />e; � <br />. . . . . . . . __ . _ _ . . _ <br />Location of Ducts <br />Instruciio3is _ <br />.� CondiUonea Space � � � �� <br />'�a _.�;r .. p _ _ _ <br />Fiqure 1. <br />,�_.,,, <br />^ I Above Grade �� <br />; _ .- <br />. .. .
