2. Standard for the Design of High Performance Green Buildings
Timeline of Standard 189.1
Standard for the Design of High Performance Green Buildings
2006: Development started
2009: First version published
2011: Revision published
2012: IgCC Published: is compliance option
2014: Revision published
2017: Revision forthcoming

3. International Green Construction Code IgCC and Standard 189.1
Standard 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 and IgCC to identify opportunities to improve standard

4. Environmental impacts of buildings
U.S. buildings impact as a % of Total Economy
Other impacts: site biodiversity; rainwater management; environmental emissions; construction materials and waste

5. Standard 189.1 “101”: Co-Sponsors
ASHRAE +
ICC
IES
USGBC

6. 189.1 Builds on Other ASHRAE Standards

7. 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

8. Standard 189.1: Purpose and Scope
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

9. 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
#.5 Performance requirements OR
Can do Prescriptive or Performance section-by-section, e.g., prescriptive for water but performance for energy

10. 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

11. 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

12. Environmental impacts of buildings
U.S. buildings impact as a % of Total Economy
Other impacts: site biodiversity; rainwater management; environmental emissions; construction materials and waste
