The Green Standard Standard , Standard for the Design of High-Performance Green Buildings

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 (same as ASHRAE/IES Standard 90.1) Optional compliance path to the International Green Construction Code Not a design guide or a rating system

Standard Provides Mandatory criteria in all topic areas Simple prescriptive compliance options Flexible performance compliance options Complement green building rating programs

Sponsors and Project Committee  Sponsor and co-sponsors: – ASHRAE – USGBC (U.S. Green Building Council) – IES (Illuminating Engineering Society)  Project committee: 35+ voting members; variety of disciplines, industries & organizations

Standard Building Blocks

Standard Topic Areas Sustainable Sites Water Use Efficiency Energy Efficiency Indoor Environmental Quality Building’s Impact on the Atmosphere, Materials & Resources Construction and Operations Plans

Standard Basic Structure x.1: Scope x.2: Compliance x.3: Mandatory (required for all projects) x.4: Prescriptive path (simple option, minimal choices, very few calculations) x.5: Performance path (more sophisticated, flexibility, but more effort)

Compliance Paths + + (simple option, very few calculations) (more options, but more effort)

Sustainable Sites

Sustainable Sites Highlights  Site Selection  Reduce heat island effect  Reduce light pollution

Water

Water Use Efficiency Mandatory Provisions  Site water use  Building water use  HVAC Systems, equipment  Water consumption management

Energy

Energy Efficiency Original Standard goal 30% lower than Standard INCLUDING PROCESS Standard goal 5-15% lower than Standard Appendix G from Standard 90.1 is incorporated as a Normative Appendix

Energy Efficiency Mandatory requirements  Renewable energy provisions  Remote or automatic reading meters criteria based on size  Meters communicate to central recording system  Data storage for minimum 36 months

Indoor Environmental Quality

Highlights  Outdoor airflow  Tobacco smoke control  Outdoor air monitoring  Filtration and air cleaning  Daylighting  Thermal comfort  Acoustics

Building’s Impact on Atmosphere, Materials and Resources

Mandatory: Construction waste management No CFC based refrigerants Recyclables storage areas

Construction and Operation Plans

Construction and Operation Highlights Building acceptance testing/commissioning IAQ construction management plan Plans for operation -High performance building operation -Maintenance -Service Life -Transportation Management

Why Consider Adopting Standard 189.1?  Minimum green building requirements developed using ANSI consensus process with b alanced committee, consensus must be reached by materially affected parties  ASHRAE and USGBC offers training to code officials on detailed requirements of standard
