From the editors of Condé Nast Traveler:

From an in-room key card system that controls lighting and temperature (reducing energy consumption by 20 percent) to whimsical drapes and carpets fashioned from recycled materials, this 86-room hotel's eco-friendliness scored a hallowed LEED rating from the U.S. Green Building Council, one of only a handful of U.S. hotels to receive one. Still, Orchard Garden doesn't sacrifice environment in the name of environmentalism: The Egyptian cotton bedspreads are silky soft, the attractive furnishings are constructed of maple harvested from a sustainable forest, and sleek modern fixtures hold compact fluorescent light bulbs. While the service is still working out some kinks, Roots, the on-site eatery, offers a tasty menu of naturally raised meats and sustainably caught seafood. Best of all, this Union Square hotel saves not only the planet but also your wallet.
