2. Overview
 Why Sustainable / Green Building
 10 Key Sustainable Building Categories
 Sustainable / Green Building Standards
 Case Study, Abercorn Common
 Other Examples in Different Countries
 Q/A Session

3. Why not?Why not?
Why Sustainable/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.

4. 10 Sustainable Building Categories
 Indoor Environment Quality
 Energy Efficiency
 Water Efficiency
 Stormwater Management
 Building Materials
 Transportation
 Waste Management
 Urban Ecology
 Innovation
 Construction and Building Management

5. Sustainable/Green Building Standards
• USGBC - LEED (US,)
Leadership in Energy and Environmental Design
Silver, Gold, and Platinum standards
• HKBEAM (Hong Kong)
Hong Kong Building Environmental Assessment Method
• BREEAM (UK)
Building Research Establishment Environmental Assessment Method
CASBEE (Japan)
Comprehensive Assessment System for Building Environmental
Efficiency
Green Star (Australia)
Buildings rated on 6 star scale, with 6 being highest

7. Case Study (example)
Abercorn Common
Savannah, Georgia
UNITED STATES
Abercorn 1980 Abercorn Now

8. Abercorn Common Shopping Center, 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 (Porous Concrete)
• 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
The Cistern harvests rainwater from rooftops, 5 million gallons annually

11. Other Features
• Low-flow toilets & Faucets and
waterless urinals – reduce water use
• Tighter envelope, better glazing &
high efficiency HVAC & lighting to
reduce energy consumption

12. Other Features (Cont’d)
Located ¼ 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
• Stringent construction 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% more energy 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
