Heatina Svstem Size: Washinaton State
<br />The glazing (window) and door portion of this calculator assumes the installed giazing 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 ail 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. 11' you do not see the selection you need in the drop-down options, please call the WSU Energy Extension
