Simple Heating System Size: Washington State
This heating system sizing calculator is based on the Prescriptive Requirements of the 2015 Washington State Energy Code(WSEC)and ACCA
Manuals J and S.This calculator will calculate heating loads only.ACCA procedures for sizing cooling systems should be used to determine cooling
loads.
The glazing(window)and door portion of this calculator assumes the installed glazing and door products have an area weighted average U-factor of
0.30. The incorporated insulation requirements are the minimum prescriptive amounts specified by the 2015 WSEC.
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,
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
Program at(360)956-2042 for assistance.
