Phipps Conservatory, Pittsburgh

Arguably the greenest venue on our list, the Phipps Conservatory in Pittsburgh recently built a Tropical Forest Conservatory. The new greenhouse uses state-of-the-art ventilation, earth tubes, radiant heating, and computer controlled shading and fogging to create a tropical environment with the absolute minimum consumption of energy. Phipps also offers tours of its research-oriented Center for Sustainable Landscapes and its energy-efficient production greenhouse. The other sections of Phipps feature different ecosystems, while popular areas like a Victorian garden, orchid room and palm tree forest appealing to those who want a classic conservatory experience.
