what is standard 189 1
What is Standard 189.1?
  • ANSI standard being 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 project committee 189 1
Standard Project Committee 189.1
  • Sponsor and co-sponsors
    • ASHRAE - American Society of Heating, Refrigerating and Air Conditioning Engineers
    • USGBC – U.S. Green Building Council
    • IES - Illuminating Engineering Society of North America
  • Project committee
    • 37 total members
    • Diverse backgrounds
  • Consensus process with four public reviews
goals for standard 189 1
Goals for Standard 189.1
  • Establish mandatory criteria in all topic areas
    • One “challenge” is existing green building rating systems contain few mandatory provisions
  • Provide simple prescriptive compliance options
  • Provide flexible performance compliance options
  • Complement green building rating programs
    • Standard is not intended to compete with green building rating programs

why consider adopting standard 189 1
Why Consider Adopting Standard 189.1?
  • The minimum green building requirements have been developed using an ANSI consensus process with four public reviews over the past three years
  • ASHRAE/USGBC can offer training to code officials on the detailed requirements
