- 3. Why not?Why not? WhySustainable/Green Buildings? Sustainable buildings cost less to heat, cool and light. That means lower operating costs for the owner. Sustainable buildings have shown improved comfort and performance for the occupants. That translates into higher sales prices and rents for the builder and developer. Sustainable buildings produce less pollution because they use less energy. They make wisely use natural resources in their construction by lowering the consumption of building materials. Most importantly, they are healthier spaces to live and work.

- 8. Abercorn Common ShoppingCenter, Savannah GA. – A Case Study Vegetated Roof & White Roof Membrane to Reflect/Absorb Heat and Keep Center Building Cooler Pervious pavement diverts storm water Concrete paving reflects heat, keeping the center and parking lot cooler Sustainable Features
- 9. Pervious Pavement (PorousConcrete) • Almost 1 acre of pervious pavement, which allows water to infiltrate the ground (runoff coefficient of .3 vs .95 for traditional concrete) • Decreases the need for municipal stormwater treatment • Helps remove sediment and pollutants • Decreases site runoff by 25%
- 10. The Cistern System TheCistern harvests rainwater from rooftops, 5 million gallons annually
- 11. Other Features • Low-flowtoilets & Faucets and waterless urinals – reduce water use • Tighter envelope, better glazing & high efficiency HVAC & lighting to reduce energy consumption
- 12. Other Features (Cont’d) Located¼ mile from 3 bus stops, preferred parking for hybrid vehicles; bike racks & changing facilities – encourages use of carpooling & alternate transportation
- 13. Indoor Environmental Quality •Low-emitting paints, sealants and adhesives used – Zero or low volatile organic compounds (VOCs) • No smoking (including restaurants) – before GA became non- smoking • Increased ventilation – 30% over ASHRAE 62
- 14. Waste Reduction • Stringentconstruction waste management practices – prevented 85% of construction waste from landfills • Over 6,000 tons were recycled or reused
- 15. Material and Resources •Over 70% of materials manufactured within a 500 mile radius • Over 20% recycled materials by cost
- 16. Summary is: 30% moreenergy efficient than code (ASHRAE 90.1) 55% more water efficient (than 1992 Energy Policy Act) Healthier indoor air – less toxins and more fresh air Has 30% Less stormwater runoff Uses no potable water for irrigation
