International Green Construction
Code IgCC and Standard 189.1
• Standard 189.1-2017 re-write in progress
• 189.1 to be technical core of IgCC and LEED
• Same ASHRAE Committee has charge
• Added more members with code experience
• ICC will develop administrative and
enforcement structure
• Comparing 189.1 and IgCC to identify
opportunities to improve standard

Summary of 189.1
• Site provisions to reduce landscape impact, urban heat
island, light pollution and storm water runoff
• Water-use provisions to reduce unnecessary water use
• Energy-use and efficiency provisions to reduce energy
use, emissions and peak demand
• IEQ provisions to help keep building occupants
comfortable, healthy and productive
• Materials provisions to reduce impact on resources as
well as earth and atmosphere (reduce, reuse, recycle)
• Construction and plans for operation to help the HPGB
operate as intended by design team
Standard 189.1: Purpose and Scope
PURPOSE:
 Siting, design, construction & plan for operation
 Support development that meets needs of present without
compromising ability of future generations to meet their needs.
SCOPE:
 New buildings; new systems and equipment in existing
buildings
 Commercial, institutional and high-rise residential buildings
Purpose and Scope in revision process
Section 4: Administration and Enforcement
Each section, except 5 (Site) and 10 (Construction
and Plans for Operation), organized as follows:
#.3 Mandatory
requirements
#.4 Prescriptive
requirements
OR
#.5 Performance
requirements
Can do Prescriptive or Performance section-by-section,
e.g., prescriptive for water but performance for energy
Federal Preemption: Efficiency Standards
• Municipalities may not exceed federal
• Federal Court voided 2007 Albuquerque code
that mandated more stringent efficiencies
• Manufacturer trade group (AHRI) “gratified”
• ASHRAE does not have a position
• Local and state governments may enact market based
incentives instead of mandatory codes
• For more info, see Schatmeier, “Avoiding Albuquerque,”
Columbia Journal of Environmental Law, 2012 –
December 19
Section 7: Energy Efficiency
7.3 Mandatory:
Prep for renewables, Measurement devices, record and store
data, PLUS
OR
7.4 Prescriptive:
Insulation, HVAC, hot water,
lighting, install renewables
7.5 Performance:
Computer simulation to
demonstrate energy, CO2
emissions and peak demand
better than prescriptive
