Simple Heating System Size: Washin ton State <br /> This hea,tinq svstem sizinq calculator is based on the Prescriptive Requirements of the 2012 Washington State Energy Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heating loads only ACCA orocedures for sizin9 cooling systems should be used to determine coolinp <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 /> P�oject Information Contact Information <br /> P{an 2006 <br /> Heatin4 System Tvpe: O Forced Air Furnace Q Heat Pump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> ��`��`�"'''��" - - - - ' Design Temperature Difference(4T) 49 <br /> Everett Pame AFB � �T=Indoor(70 tlegreesJ-Outdoor Design Temp <br /> � _ w: ;4�..:� <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> i�''�';���'"'�`� Conditioned Floor Area(sq ft) 2,006 <br /> Average Ceiling Height Conditioned Volume <br /> �"';i`"::�;":; Average Ceiling Height(ft) 8.5 17,051 <br /> Glazinq and Doors U-Factor X Area = UA <br /> #`"�`�`''`'�� 0.30 334 100.05 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> 3.._..£�..1£;'30115 . . . . ___._ _ ."_— $ <br /> R-as �� 0.026 1,431 37.21 <br /> �, ,;�> .�-. <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> .nsirca�`;r�ns _ _----- �- ' � <br /> No Vaulted Ceilings in this project. � .� '-' <br /> � <br /> Above Grade Walls�SeeF;yure t� U-Factor Area UA <br /> €"'�`'�`'"�'�` ����--- - 0.056 2,390 133.84 <br /> ,R-21 �.�_� <br /> Floors U-Factor Area UA <br /> ':r;s.;tr�acti.3�,s _. _--.-----.------- -,—______. <br /> �,R-30 �,�� 0.029 1,300 37J0 <br /> ��.-y.:..._, _ <br /> Below Grade Walls�see Fr9�.e�� U-Factor Area UA <br /> f[tsf.rttr..Ei<:�n.s � <br /> -No Below Grade Walls in this project. � '-- "' <br /> Slab Below Grade/see Fry�.e�� F-Factor Length UA <br /> Eii"i�P"�,i W?IOSYS � � <br /> �.No Slab Below Grade in this pro�ed. • , --- <br /> ._ •.;*a�:�•« _....._____. ��-- ���,: :.� <br /> Slab on Grade�5ee Fry�.e�� F-Factor Length UA <br /> !4"SYPc:G;EIIt"i� . _ . _. __.. .-.—� i � <br /> No Slab on Grade in[his project � � --- <br /> � <br /> Location of Ducts <br /> ir�struz;-�,}r�� <br /> - � Duct Leakage Coefficient <br /> Unconditioned Spa[e �%A� 1.10 <br /> t+.....__-�:d.. :�a.. <br /> Sum of UA 308.80 <br /> Envelope Heat Load 15,131 etu/Hour <br /> F iq U f0 1.
