It recommends reviewing the Manual J report starting with design conditions and then scanning page two for zero values, fixing issues such as an exterior door misclassified as interior and ducts set to non-ducted despite being duct wire in an unconditioned basement. It also flags large load contributors like floors, checking page three for inconsistencies in insulation and window performance metrics such as U-value and SHGC. The presenter demonstrates correcting a clear single-pane window and inconsistent wall construction (2x4 versus 2x6) to make assumptions consistent across the home."}
