ASHRAE/USGBC/IES Standard 189.1-2009 What Does It Mean for
Commissioning Providers?
STANDARD 189.1 – WHAT DOES IT MEAN FOR COMMISSIONING PROVIDERS? 2
What is Standard 189.1?
ANSI standard developed in model code language Provides minimum requirements for high-performance,
green buildings Applies to all buildings except low-rise residential buildings
(same as ASHRAE/IESNA Std 90.1) Optional Compliance Path to the International Green
Construction Code (IgCC) Not a design guide, not a rating system
STANDARD 189.1 – WHAT DOES IT MEAN FOR COMMISSIONING PROVIDERS? 3
Goals for Standard 189.1
Establish mandatory criteria for green buildings that result in buildings that are designed, constructed and operated to maintain high levels of performance in the key areas of the standard.
Provide simple compliance options Complement green building rating programs Standard is not intended to compete with green building rating
programs
