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
