<br /> Simple Heating System Size: Washl�fon State �
<br /> This heatinq system sizinq calculator is based on the Prescriptive Requirements of tiie 2012 Washinqton State Enerqy Code(WSEC)and ACCA
<br /> Manuals J and S.This calculator will calculate heatinq loads only.ACCA procedures for sizinG cooiinq 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:irop-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.
