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

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 Standard189.1?

The minimum green building requirements have beendeveloped using an ANSI consensus process with four

public reviews over the past three years

ASHRAE/USGBC can offer training to code officialson the detailed requirements
