12. MINIMIZE THERMAL BRIDGING
Optimal Value Engineering (OVE)
“California Corners” that use two instead of three studs to frame
corners
Single top plates instead of double plates
24” on center studding instead of 16” on center framing
Continuous insulation in stead of cavity filled insulation
Reducing or eliminating thermal bridging
