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


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


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
