Sim�!e Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washinqton State Enerqy Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heating loads onlv ACCA procedures for sizinq coolinq systems 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 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 /> Plan 2070 <br /> Heatinq Svstem Tvpe: � Fo���a��F���a�e �Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> '���������F`���' � � �� � � � � � � �� � '� Design Temperature Difference(4T) 49 <br /> Everett Paine AFB • j <br /> � � 1T=lndoor(70 degrees)-Outdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> """'"'"''`� Conditioned FloorArea(sq ft) 2.070 <br /> Average Ceiling Height Conditioned Volume <br /> °` �• � ° Average Ceiling Height(ft) 8.5 17,595 <br /> Glazincl and Doors U-Factor X Area = UA <br /> '������_�"�� 0.30 29Q 87.00 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> ->�r��ce;r,»s __ _ _ � 0.026 1,280 33.28 <br /> R-49 � � <br /> - a:::�. ..� <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> -�a�i��'f.:nY?J _ . . . . . _ .. ._...�__._=. i ___ � <br /> No Vaulted Ceilings in this project � <br /> , <br /> Above Grade Walls(5ee Fry�re�� U-Factor Area UA <br /> ------- <br /> _ ���`_�;��'`=; �–-�--�— 0.056 2,340 131.04 <br /> R-71 � <br /> . <br /> � <br /> , .: ,-i <br /> Floors U-Factor Area UA <br /> __ . ___-------__._.----_------ <br /> r��r�����:r��� � ' 0.029 1.280 37.12 <br /> R-30 � 9 <br /> � <br /> Below Grade Walls�5ee F�y�.e�� U-Factor Area UA <br /> �;.r:,,s, -- 0 <br /> �... <br /> No Below Grade Walls in this projecL � ' <br /> r �s. � <br /> Slab Below Grade/see F�q�re�� F-Factor Length UA <br /> ------ ' � <br /> ,:st<>..c:;<;r,s ' --- <br /> � �No Slab 8elow Grade in this projed. � j <br /> � .. :.....:....._..-�w:t,�.�m�.a,.. -��.. �.... .-�Ci�+Y <br /> Slab on Grade�see Frq�re t� F-Factor Length UA <br /> ^r . . _ ._ __ .._... . __._. .__...__... � <br /> 3.. 3.`i':'i ' ___ <br /> 'No Slab on Grade m this project. � � <br /> h._ �a� �"�: mrtar <br /> Location of Ducts <br /> `�;-�=��s3v='u - - Duct Leakage Coefficient <br /> Un�onditioned Space � <br /> v..�...�ui�:i�....:_>.:e�,�a.:..�.� ., 1.10 <br /> Sum of UA 288.44 <br /> Envelope Heat Load 14,134 Btu I Hour <br /> Fi ure 1. s�moruax-�r <br /> ,,� Air Leakage Heat Load 9,311 Btu/Hour <br /> � VolumeX O.6XnTX.018 <br /> Ahove Grade Building Design Heat Load 23,445 Btu/Hour <br /> Air Leakage+Envelope Heat Loss <br /> °-°��^-�^ Building and Duct Heat Load 25,789 Btu/Hour <br /> Ducts in unconditioned space:Sum of Building Heat Loss X 1.10 <br /> Oucts in condilioned space:Sum of Building Heat Loss X 1 <br /> Maximum Heat Equipment Output 36,105 Btu/Hour <br /> Building and Duct Heat Loss X 1.40(or Foroed Air Fumace <br /> Building and Duct Heat Loss X 125 for Heat Pump <br /> (07/01/13) <br />
