STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS2
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 FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS3
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
STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS4
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?
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
