�ir'nple Heating System Size: Wa�--;;�ton State <br /> This heating svstem sizinq calcu�ator is based on the Prescriptive Requirements of the 2012 WashinqiUit dcate Enerqv Code(WSEC)and ACCA <br /> Manu�ls J and S This caiculator will calculate heatinq loads only ACCA procedures for sizinq cooling 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 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/nformation � .
