Category 4: Water Conservation
Minimum Energy Performance
New Homes (1-3 floors) - Energy Star Standards
Modeling to meet HERS requirements.
Mid-rise/high-rise - 15% better than ASHRAE 90.1
Modeling required, but no 3rd party testing.
Renovation - 15% improvement from existing
Requires energy audit and analysis.

Category 8: Operations and Maintenance
Project team indicates intent to meet criteria.
Identify mandatory measures and sufficient number of optional points
Submit documentation – site plan, context map
Inspections and testing conducted during construction to verify energy performance.
Key project team members certify that criteria has been built into plans and specs.
Follow-up inspections and performance testing conducted post-construction.

Green Communities Certification Process
Research Highlights
On average, it costs $5 per square foot to meet the mandatory Green Communities Criteria.
Buildings meeting the basic Criteria cut water costs by 20 percent and energy costs by 25 to 30 percent.
Healthier homes designed to reduce childhood asthma result in a 60 percent increase in symptom-free days; annual emergency room and urgent care visits fell by 67 percent.
