  2. Extending Enterprise’s Vision “What ought to be, can be, if we have the will to make it so.” - James W. Rouse

  3. Greenwashing Landfills at Capacity Drought and Desertification Sprawl Clear Cutting of Forested Land Vacant and Abandoned Homes Air Pollution

  4. IntegratedDesign Materials Beneficial to the Environment Water Conservation Energy Efficiency Location and Neighborhood Fabric Operations and Maintenance Health Green Communities Criteria

  5. Building Typologies

  6. Construction Types Roanoke & Lee – Blacksburg, VA Westgate Terrace – Rochester, NY Broadway Crossings – Seattle, WA

  7. Geographic Locations

  8. Interdisciplinary approach to integration of green measures Overview of specifications and methods to accomplishing green objectives Category 1: Integrated Design Charrette

  9. Tremont Pointe - Cleveland, OH Tremont Point, Ohio

  10. Category 2: Site Planning and Layout

  11. Site Plan

  12. Context Map KEY ----- .5 mile radius ● Schools ● Libraries ●Retail ●Doctor / Dental Clinics ●Grocery Store

  13. Atonatl Condominiums - Washington, DC

  14. Category 3: Site Improvements 14

  15. Spring Terrace – Austin, TX

  16. Category 4: Water Conservation Faucets = 2.0 GPM or less Showerheads = 2.0 GPM or less Toilet = 1.3 GPF or less, that meet performance specification www.cwwa.ca/freepub_e.asp Front load washers save 60%+ 17

  17. 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 5: Energy Efficiency

  18. HERS Rating Certificate

  19. Tight Construction

  20. Improved Insulation Systems

  21. Poorly Installed Fiberglass Batts Insulation What’s wrong with this picture?

  22. HVAC System Efficiency

  23. Red Flags Whole - building energy performance

  24. ENERGY STAR Appliances and Efficient Lighting

  25. Red Flags Efficient Lighting

  26. Ripley Gardens – Minneapolis, MN

  27. Category 6: Materials Beneficial to the Environment

  28. Waste Reductions – delivery or disposal?

  29. Category 7: Healthy Living Environments Slides Courtesy of Tom Phillips, Seattle Housing Authority

  30. Reducing VOCs

  31. Ventilation – Whole House and Exhaust

  32. ASHRAE Ventilation Standards • 62.1 applies to all spaces intended for residential structures except those within single-family houses, multifamily structures of three stories or fewer above grade. • 62.2 applies to spaces intended for single-family houses and multifamily structures of three stories or fewer above grade.

  33. Kitchens Vented to Exterior • Kitchens vented to the exterior • At least 100 CFM flow or 20 CFM continuous run

  34. Red Flags Ventilation

  35. Red Flags Moisture Mitigation

  36. Radon Mitigation Zone 1 - Highest Potential (greater than 4 pCi/L) Zone 2 – Medium Potential (greater than 2 pCi/L)

  37. Viking Terrace – Worthington, MN

  38. Manual & Orientation/Training O&M info Warranty procedures Thermostat settings Community amenities What to expect Category 8: Operations and Maintenance

  39. 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. http://www.greencommunitiesonline.org/tools/certification_process.asp Green Communities Certification Process

  40. 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.
