The WAP Effect High-Efficiency Windows & The Dilemma (Tyranny?) of Audit Algorithms

Today Walls Beat Windows Clients want windows Energy-savings restrict Uninsulated walls improve from R-2 to R-19 Windows improve from R-1 to R-2 Relative SF favors wall insulation Replace broken or missing windows only
