S"smple Heating System Size: Wa;:;::�„gton State
<br /> � a Th�is heating svstem sizinq calculator is baseu vir••�e Prescriptive Requirements of the 2012 Washinc�#ate Eneray Code(WSEC)and ACCA
<br /> Manuals J and S This calculator will calculate heatinq loads oniv ACCA procedures for sizing coolinq systems 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 wiil be caiculated for you.If you do not see the selection you need in the drop-down options,please call the WSU Energy E�ension
<br /> Program at(360}956-2042 for assistance.
