� � � `�, b�d s y q � � <br />� Sim le Heatin S stem Size: Washin ton State � � �'� <br />P 9 Y 9 <br />This heatina svstem sizinq calculator is based on the Prescri�tive Reauirements of the 2012 Washinaton State Enerqv Code (WSECI and ACCA <br />Manuals J and S. This calculator will calculate heatinq loads onlv ACCA procedures for sizina coolino 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 }rour project. As you make selections in the drop-downs for each section, <br />some values will be calcwlated for you. If you do not see the selectian you need in the drop-down op6ons, please call the WSU Energy Extension <br />Program at (360) 956-2042 for assistance. <br />Project Information Contact Info�mation <br />Unit El Townhome Polygon Northwest <br />Silver Lake7ownhomes Alaina Robertson <br />Everett, Washin ton (425) 606-OOQS <br />H@atII1Q Sj/Si@I'TI TVPe: �O Forced Air Fumace Q Heat Pump <br />To see detarled instructions for each section, place your cursor on the word "lnstrucfions". <br />Desiqn Temperature <br />�„str��c�io:,s V __ �_. _.:. � Design Temperature Difference (4T) <br />l EVerett )C �`A�. � �T = Indaor p0 degiees) - Outdoor Design Temp <br />Area of Buildinq <br />Conditioned Floor Area <br />ensiru�i�o„� Conditioned Floor Area (sq ft) <br />Average Ceiling Height <br />!��t�L11iO:'� Average Ceiling Height (ft) <br />Glazinq and Doors <br />insiriecticns <br />Insulation <br />Attic <br />l;,sirucifur:s ___.� _ . _ _ _ <br />� R-49 • ;� <br />k - - <br />Single Rafter or Joist Vaulted Ceilings <br />9nsYructio�s � _ _. __ <br />fvo Vaulted Ceflings In thls proJecL ���`� <br />- _ __ _ ..::,..s_,y�;y, �"^'v�f <br />Above Grade Walls �sre FrHure �I <br />Instruciions � — <br />R21 ��;� <br />� _ �;-�� =u:.� f�r: :-:���� <br />Floors <br />�nstructio�ss -- l <br />R-30 � a.; <br />� __.... v;.,.. , .--- _,..��al <br />v�� � <br />Below Grade Walls �:K Frg�re �i <br />Ir:struct;cns _ ----�_. __ _.___ <br />E No [ielow Grade Walls m thls projec[. ��� <br />4�. ,�.:�.. . e �..�� i <br />' <br />Slab Below Grade rsK Fiou.� u <br />iP15ifLICY1G115 � ' __'__.__..__._._J.._ ..._.__..� �_..."___`_ <br />� No Slab Below Grade In thfs pro�ect �•t �I <br />Slab on Grade �s�� Fipure�fi <br />Instructions � ---- —�--`------- <br />R-10 Penmeter � ,� <br />� , ��������m��m� <br />Location of Ducts <br />��sr,,��t;�r_ _ __ _. _. <br />� --- — — – <br />� CondiGoned Space � � <br />v�:� " -� z _- F <br />Fiqure 1. <br />� �¢� ��_ <br />Above Gnde <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 />0.026 602 15.65 <br />U-Factor <br />U-Factor <br />0.056 <br />U-Factor <br />0.029 <br />U-Factor <br />F-Factor <br />F-Factor <br />0.540 <br />Sum of UA <br />Area UA <br />� <br />Area UA <br />413 23.13 <br />Area UA <br />345 10.01 <br />Area UA <br />� -- <br />Le__ngth UA <br />� <br />Len th UA <br />66 35.64 <br />Duct Leakage Coefficient <br />1.00 <br />138.85 <br />47 <br />Envelope Heat Load 6,526 Btu / Hour <br />Sum a!
