Simple Heating System Size: Vllashington State <br /> This heatina svstem sizinq calculator is based on the Prescriptive Re4uirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatina loads onlv ACCA procedures for sizina coolinq 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 specifed 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 ES Townhome Polygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> H@8tIf1Q SYStBfll TVPe: OO Forced Air Furnace 0 Heat Pump <br /> To see detailed instructions for each section,p/ace your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> insiruct�ons � .___.__ -._._____ �....� � � Design Temperature Difference(AT) 47 <br /> �j Everett JC _ _ _ pT=Indoor(70 degreesJ-Outdoor Design Temp <br /> ;r <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> in`'n"uc�'°ns Conditioned Floor Area(sq ft) 1,344 <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) 8.5 11,424 <br /> Glazinq and Doors U-Factor X Area = UA <br /> �nstructions 0.30 183 54.78 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions �----- ---- — ..-! — <br /> il R-49 .J � 0.026 591 15.37 <br /> � .._.. _._... ____ ,. - <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Instruc[ions ..__ ._—._ ...�� ---- � r� <br /> --- <br /> I� No Vaulted Ceilin s in thts ro�ect � �_� <br /> � � <br /> '---. . _.__9 P ..-- <br /> Above Grade Walls�see F,9�re a� U-Factor Area UA <br /> Instructions � ----�...------.___.. � <br /> � �R-zi ___ � I 0.056 413 23.13 <br /> �—_..—a�- � i <br /> Floors U-Factor Area UA <br /> Instructions I —'" --" _� � 0.029 345 10.01 <br /> � j R-30 _� � <br /> Below Grade Walls�seeFry�re+� U-Factor Area UA <br /> Instructions � .— -- .�...—. . — I � <br /> � i No Below Grade Walls in this pro�ect � i <br /> i .___- _'_ ' —_ �o,ul1 <br /> Slab Below Grade�see F,9���� F-Factor Length UA <br /> � _ _--- -- — -- �� <br /> Instructions � --- <br /> � No Slab Below Grade tn this prqect <br /> l .. . .. --- � -- --_.__ _._-- <br /> s,_ _ <br /> y,,,��� F-Factor Length UA <br /> SlabtOntGredO(see Fil R-10 Perimeter � 0.540 34 18.36 <br /> -�� <br /> — -:�s - - - <br /> Location of Ducts <br /> Instructions � __.__ --_.. -_.—._-_.. --� � Duct Leakage Coefficient <br /> Condrtioned Space � <br /> — 1.00 <br /> Sum of UA 121.64 <br /> Envelope Heat Load 5,717 Btu/Hour <br /> Fiqure 1. s�morunxor <br /> ��` Air Leakage Heat Load 5,799 Btu!Hour <br /> �'`�� _ _�� VolumeX O.6X�TX.018 <br /> Above Grade Building Design Heat Load 11,516 etu/Hour <br /> AirLeakaqe+Envelope Heat Loss <br /> �Be�ow�rade D H tLoad 11516 etulHour <br /> Building and uct ea , <br /> � Ducts in unconddibned space:Sum oI Building Heat Loss X 1.10 <br /> Ducts in conditioned space:Sum of Building Heat Loss X 1 <br /> Maximum Heat Equipment Output 16,122 Btu!Hour <br /> Building and Duct Heat Loss X 1.40 fo�Forced Air Fumace <br /> Building and Duct Heaf Loss X 1.25 fo�Heat Pump <br /> i <br /> � � (07/01/13J <br />
