  1. 1. Building with Rural DevelopmentSupporting Construction Innovations for a More Affordable Future
  2. 2. Renewable• Straw Bale – Passive Solar – Climate appropriate – Moisture control – Self Help and Youth organizations (Student Interns) – Built for low income families sometimes replacing deteriorated trailer homes. • Trailers are recycled and owners are provided temporary housing
  3. 3. Structural Insulated Panels• New Construction  Above and Below ground• Retrofit Existing  Exterior application
  4. 4. Multi-Family Housing Net Zero• Net Zero goal – A Challenge worth pursuing – Energy efficient techniques – Conservation strategies – Energy generation
  5. 5. “Net Zero” Success Stories• Harvest Point – Salem NJ – Existing Retrofit/Renovation – – Original construction 1976-1978 • 18 Buildings • 2010 Renovation and 3 new facilities added for general tenant use. Energy Star Certified 2009 Tier 2 level of performance
  6. 6. Harvest Point cont.• Added insulation• Efficient lighting• Efficient HVAC• Energy Star appliances – Furnace – HWH - Tankless – Thermostat – Exhaust fans – Low – E windows
  7. 7. Harvest Point cont.• Rain water collection – Central courtyard collection area populated with deep rooted native plants for absorption. – Drought resistant. – Light textured soils and mulch mixture replaced native soil. • Capable of metabolizing oil- based pollutants from parking lot runoff
  8. 8. Harvest Point cont.• Unabsorbed water – Percolates through coarse backfill to aquifer or into high density pipes leading to storm system Low flow fixtures sinks toilets showers
  9. 9. Montgomery Crossing - CA• New Construction – Exceeds CA energy code by 18% – Designed/planned for family interaction – 28.1 kWh of photovoltaic system – Foam backed insulated vinyl siding – extended useful life – Low flow plumbing fixtures – Drought resistant plants
  10. 10. Rancho Lindo - CA• New Construction – Exceeds CA energy code by 37% – Build It Green Certified 42,000 kWh grid tied photovoltaics Tile roof allow 54% solar reflectance saves on cooling costs. Low –e windows Tankless hwh Energy star appliances
  11. 11. Rancho Lindo cont.• Passive solar orientation and design with appropriately placed (south and west) deciduous trees• Material saving techniques – load bearing door and window frames are other unique framing practices• Recycled materials• Synthetic turf and drip irrigation• Native plants with low water needs
  12. 12. Rancho Lindo cont.• Minimizing the carbon foot print – Walking distance to schools, groceries, public park and community services. – Onsite learning center and after school programs
