a, <br /> Simple Heating System Size:Washington State <br /> This heating system sizino 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 procedures for sizing tooling systems should be used to determine cooling <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#2064 PAUL BUSTARD <br /> 42S-876-655i <br /> Heating System Type: rim,Forced Air Furnace 0 Heat Pump <br /> To see detailed instructions for each section,place your cursor on The word"instructions" <br /> Design Temperature <br /> tn'tructians :..
