This c� Icul�tor �.^✓iil calcul_ate heatinq louds enlv- ACCA proc�c�ures for si-r_inq coolinq systems should be used to dctzrmine cooliii <br />loads. <br />The giazing (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 eash section, <br />some values will be calculated for you.
