Time Equities, Inc. just broke ground on 50 West Street, Manhattan's newest green condo and hotel skyscraper. Designed by influential architect Helmut Jahn, the $600 million, 580,000 sf mixed-use eco-tower is shooting for LEED Gold certification upon completion in 2011. As a result, the 65-story tower will incorporate a host of green features and measures, including a green roof, water-efficient fixtures, automated blinds and energy control systems, recycling of demolition materials, use of sustainable and rapidly renewable materials, and an energy-efficient glass facade to filter in daylight and filter out UV rays.
