Simple Heating System Size: Washington State <br /> This heatinq svstem sizinq calculator is based on the Prescriotive Requirements of the 2012 Washinaton State Enerav Code(WSEC)and ACCA <br /> Manuals J and S This calculator will calculate heatinq loads onlv ACCA procedures for sizina coolinq svstems 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 /> Project Information Contact Information <br /> Unit ES Townhome Polygon Northwest <br /> Edipse Jamie Aubrey <br /> Everett,Washington (4Z5)586-7700 <br /> Heatinq System Type: O Fo��ed a��F���a�e Q hleat Pump <br /> To see detailed instructions for each secfion,p/ace your cursor on the word"Instructions". <br /> Desiqn Temperature <br /> Instructions ` .. . ... .. _....-..... . -_-1 � Design Temperature Difference(4T) 47 <br /> ( Everett 1C �I OT=Indoor(70 degrees)-Outdoor Design Temp <br /> Area of Buildinq <br /> Conditioned Floor Area <br /> insreuccion5 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 /> Instructions 0.30 183 54.78 <br /> Insulation <br /> Attic U-Factor X Area = UA <br /> Instructions l �R-,�� _ -- �:v ;I ' 0.026 591 15.37 <br /> InstrucUons st Vaulted Ceilings U-Factor Area UA <br /> 9 � I_..__._.__.______--__.._:_.._----.� I � <br /> Sin le Ra er or oi <br /> ,No Vaulted Ceilings in this projed � <br /> .__.. ... ,�._,_—a-.�,�--� .�_�::: �.�.::,..J <br /> ��_ _ <br /> Above Grade Walls�SeeF;g���1 U-Factor Area UA <br /> Instructions ' _.. ..-......._....__-------_:.,..:--:�__.�_--- <br /> ; �i R_Zi .� , 0.056 413 23.13 <br /> l <br /> Floors U-Factor Area UA <br /> _ __ <br /> Instructions � R 30 _ -"' `- � � 0.029 345 10.01 <br /> Below Grade Walls�sea F;9�re�� U-Factor Area UA <br /> Instructions I ...__ .-- .__— ._.. ..
