Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriptive Reauirements of the 2012 Washinqton State Enerqv Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads onlv ACCA orocedures for sizinq 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 specified by the 2012 WSEC. <br /> Please fill out all of the green drop-downs and boxes that are appiicable 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 Informalion Contact Information <br /> Unit E3 Townhome Palygon Northwest <br /> Eclipse Jamie Aubrey <br /> Everett,Washington (425)586-7700 <br /> HBBtIIIQ SVSY@fll Typ@: O Forced Air Fumace �Heat Fump <br /> To see detailed instructions for each section,place your cursor on the word"Instructions". <br /> Desipn Temperature <br /> inscruciions _.._.___�_ . � I Design Temperature Difference(�T) 47 <br /> ' �Everett 1C � oT=Indoo�(10 deqreesJ-OutdoorDesign Temp <br /> �--�� .. _.. ... .. . <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> instruccions Conditioned FloorArea(sq ft) 1,560 <br /> Average Ceiling Height Conditioned Volume <br /> Instructions Average Ceiling Height(ft) 8.5 13,260 <br /> Glazinq and Doors U-Factor X Area = UA <br /> Instructions 0.30 241 72.27 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions III i'— � 0.026 688 17.89 <br /> �i R 49 __i ,b:ueJw� <br /> Single Rafter or Joist Vaulted Ceilings U-Factor Area UA <br /> Inslructions , -- ._.--. .__.. ._ --. � <br /> � 'No Vaulted Ceilings in this pro�ect �_I � <br /> ( --- �- -- - - - _ . <br /> Above Grade Walfs�SeeFr9�,�+1 U-Factor Area UA <br /> �nstructions � ;-- _ _-- _ -`-.• � - _ _ —� � 0.056 1,801 100.86 <br /> �R-21 <br /> � � <br /> Floors U-Factor Area UA <br /> Instructions j � _ �-.-- . _.:.. __� J <br /> i I R_30__ �v ] 0.029 430 12.47 <br /> � <br /> Below Grade Walls�SeeF;9�.�+� U-Factor Area UA <br /> Instructions � .._ ___.. . � -- - __� � <br /> INo Below Grade Walls m this pro�ect � <br /> � �.._.... _.. ....._._ -___- ,.+�.,.,.:�y ...__" <br /> Slab Below Grade�see Fig�re�� F-Factor Length UA <br /> Instruclions j .._.._-----...--------�-�-�---�—�� I � <br /> "No Slab Below Grade in this project. <br /> ; � <br /> � __.__.._......._.__.___._----^-----...__..----- <br /> Slab on Grade�5ee F;y�B�� F-Factor Length UA <br /> Instructions �- — -- -��� -- � <br /> '-- 0.540 75 40.50 <br /> ( �R-10 Penmeter � <br /> Location of Ducts <br /> Instructions � ,._ _._._._ ___._ _._.. . _� Duct Leakage Coefficient <br /> { �ConditionedSpace � � ,1.00 <br /> [ � <br /> Sum of UA 243.98 <br /> Envelope Heat Load 11,467 Btu/Hour <br /> Fiaure 1. s„moruaxor <br /> �,,,,.��Y Air Leakage Heat Load 6,731 Btu/Hour <br /> VolumeX O.6XdTX.018 <br /> nbo�e e�aae Building Design Heat Load 18,198 etu/Hour <br /> Air Leakage+Envelope Heaf Loss <br /> eei°"'�`ade Building and Duct Heat Load 18,198 Btu/Hour <br /> Ducts in unconditioned space:Sum of Building Heat Loss X 1.10 <br /> Ducts in conddioned space�Sum of Building Heaf Loss X 1 <br /> Maximum Heat Equipment Output 25,477 etu/Hour <br /> Building and Duct Heat Loss X 1.40 Por Forced Air Fumace <br /> Building and Duct Heat Loss X 1.25 Por Heat Pump <br /> f � � v <br /> I !
