Why Sustainable/Green Buildings?
Sustainable buildings cost less to heat, cool and light. Thatmeans lower operating costs for the owner. Sustainable buildingshave shown improved comfort and performance for theoccupants. That translates into higher sales prices and rents forthe builder and developer.
Sustainable buildings produce less pollution because they useless energy. They make wisely use natural resources in theirconstruction by lowering the consumption of building materials.Most importantly, they are healthier spaces to live and work.

Case Study (example)
Abercorn CommonSavannah, GeorgiaUNITED STATES
Abercorn 1980 Abercorn Now
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
Pervious Pavement (Porous Concrete)
• Almost 1 acre of perviouspavement, which allows waterto infiltrate the ground(runoff coefficient of .3 vs .95 for
traditional concrete)
• Decreases the need formunicipal stormwater treatment
• Helps remove sediment andpollutants
• Decreases site runoff by 25%
The Cistern System
The Cistern harvests rainwater from rooftops, 5 million gallons annually
Other Features
• Low-flow toilets & Faucets andwaterless urinals – reduce water use
• Tighter envelope, better glazing &high efficiency HVAC & lighting toreduce energy consumption
Other Features (Cont’d)
Located ¼ mile from 3 bus stops, preferredparking for hybrid vehicles; bike racks &changing facilities – encourages use ofcarpooling & alternate transportation
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
Waste Reduction
• Stringent construction waste management practices –prevented 85% of construction waste from landfills
• Over 6,000 tons were recycled or reused
Material and Resources
• Over 70% of materials manufactured within a 500mile radius
• Over 20% recycled materials by cost
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
