Steel city now becomes energy-efficient

 The G-20 opened its meeting in one of the most beautiful spots in Pittsburgh, a large glass-enclosed public garden that is a source of civic pride. “It is a very inspirational place, a peaceful place, a very serene place,” said Richard Piancentini, executive director of Phipps Conservatory and botanical gardens.

Piancentini said the conservatory was chosen for more than its beauty. The latest addition to Phipps, a tropical forest, is believed to have made it the most energy-efficient conservatory in the world.  The design provides for natural heating and cooling, including a unique system of vents and underground pipes to bring in fresh air. “It is like getting free air-conditioning,” Piancentini said. “It is not using any electricity, but it helps to keep the whole space cooler.” The commitment to green technology is also evident  in the city’s convention centre, the main G-20 venue, which has won awards for its environmentally-friendly construction and design.

The David L Lawrence Convention Centre, designed by the noted architect Rafael Vinoly, is the recipient of a Gold LEED (Leadership in Energy and Environmental Design) certification from the U S Green Building Council.
All this is taking place in a city that was once a major contributor to global warming.
