an enforceable baseline of compliance
– Uses the "model" code approach that provides communities
the ability to modify w/ local amendments and built-in
flexibility
• Coordinated with the ICC Family of Codes
– Is the “standard of care established by code”

– AIA
– ASTM
– ASHRAE
– USGBC
– IES
• Currently adopted by
