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 />Projecf lnformation Contact Information <br />Unit El Townhome Polygon Northwest <br />Silver Lake Townhomes Alaina Ro6ertson <br />Everett, Washin Yon (425) 606-0005 <br />Heatlilq SVSt@171 TypB: U Forced Air Furnace Q Heat Pump <br />To see detailed rnstruciions ior each secfion, piace your cursor on the word "Insfructions". <br />Desiqn Temperature <br />in�r�;cciors _ .. _. __..,: _�.�..:���__W � Design Temperature Difference (�T) <br />EverOtt JC _�� �T = Mdoor (70 deg�ees) - Outdoor Des'gn Temp <br />Area of Buiidinq <br />Conditioned Floor Area <br />in$i���;vo;,� Conditioned FloorArea (sq ft) <br />Average Ceiling Height <br />enstructio„s Average Ceiling Height (ft) <br />Glazinp and Doors <br />Instn:ctions <br />Insulation <br />Attic <br />fnstr�actioe�s I _ __ ____--------+ <br />{ N-49 � �. <br />4 <br />Single Rafter or Joist VaWted Ceilings <br />3nstruciions � . _ — --- <br />� no vaulted Cellmc�s In t�is proJect ��� <br />� _ _ _ �.- � --_ a�_,_ <br />.,.^'tti�Lf. � - <br />Above Grade Walls �:re F�e�re �� <br />Instructions -- - — <br />R 21 —�,�.<. <br />� .�u..�.� •��.ss� >„-,-.-- � <br />Floors <br />_ _ __ ___ . �- --..._._ <br />h,struciio,is � --- <br />R-30 � ,::� <br />v., ---- <br />...,...., .. � <br />_ _. ,_ ,. <br />Below Grade Watls �:KFrgure» <br />-_ ___ ____ _ _---- _______ _ <br />Instr�:ctiotts . _.._ —._�—___ <br />No t3elow Gratle Walls in lbls pro�ect. �.� <br />w w�7 <br />Slab Below Grade raee Fio�re �i � <br />Instruciions I, _ -- ----- " -- — I <br />� No Slab Below Grade in thls projett� � <br />� - � <br />Slab on Grade �see Fraure a� <br />_ -- - .. --- <br />I(tSif[1Cf;0{15 �� � <br />� R-10 Penmeier <br />�. <br />Location of Ducts <br />i�,,aPd,c��oT��; , _ _ <br />� Condiuoned Space � �, I <br />�b:.�.::.�, — ,...,W�,��.,,�..,".;.�......�...r.::,�.::��..� <br />Fiqure 1. <br />���, <br />Above Grode <br />h�+> -." <br />5,� ,� <br />_._ .. <br />1,368 <br />Conditioned Volume <br />8.5 11,628 <br />U-Factor X Area = UA <br />0.30 181 54.42 <br />U-Factor X Area = UA <br />0.026 fiD2 15.65 <br />U-Factor Area <br />� � <br />U-Factor Area <br />0.056 413 <br />U-Factor Area <br />0.029 345 <br />U-Factor Area <br />-- � <br />F-Factor Le� <br />UA <br />UA <br />23.13 <br />UA <br />10.01 <br />UA <br />UA <br />F-Factor Len th UA <br />0.540 66 35.64 <br />Duct Leakage Coefficient <br />1.00 <br />Sum of UA <br />138.85 <br />47 <br />Envelope Heat Load 6,526 Btu !
