Standard 189.1 forHigh-Performance Green Buildings
Optional Jurisdictional Compliance Path in the IgCC
STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGSX
Learning Objectives
§ Recognize the importance of developing a code-intended standard for design of high-performance green buildings
§ Differentiate Standard 189.1 from green building rating systems (e.g. USGBC LEED)
§ Identify mandatory provisions in Standard 189.1 to increase awareness of the intent of the standard
§ Identify the two compliance path options (prescriptive and performance) and their associated provisions in Standard 189.1
STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS2
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 (similar to ASHRAE/IESNA Std 90.1)
§ It is not a design guide and not a green building rating system
§ It is included as an optional Compliance Path included in the International Green Construction Code (IgCC)

Standard Project Committee 189.1
§ Co-sponsors² ASHRAE - American Society of Heating, Refrigerating and Air
Conditioning Engineers² USGBC – U.S. Green Building Council² IES - Illuminating Engineering Society of North America
§ Project committee² Large group with diverse backgrounds² North American initially
§ Consensus process
STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGS4
Why Now?
§ Voluntary green building rating programs have raised the awareness of the benefits of green building practices
§ Voluntary green building programs were intended to be voluntary and not mandatory
§ Over 1,400 jurisdictions in the U.S. have indicated they want to “green” their building codes
§ Need to reduce the environmental impact of the built environment
STANDARD FOR THE DESIGN OF HIGH-PERFORMANCE GREEN BUILDINGSX
Goals for Standard 189.1
§ Establish mandatory criteria in all topic areas² One “challenge” is existing green building rating systems contain few
mandatory provisions
§ Provide simple compliance options
§ Provide flexible compliance options to encourage innovation
§ Complement green building rating programs
