WTC Reconstruction Environmental Guidelines

In an appendix to the draft environmental impact statement for the

World Trade Center reconstruction project in lower Manhattan is a set of sustainable development guidelines that should help green the huge 16-acre (6.5 ha) development. Already, construction equipment on the site is using low-sulfur diesel fuel and high-performance filters—a requirement that will be extended citywide. Other features in the guidelines include energy efficiency measures and reclamation of water from rooftops for indoor and irrigation uses. Daniel R. Tishman, chairman of Tishman Construction—the company that built the Condé Nast Building at 4 Times Square and is now building 7 World Trade Center and the new Freedom Tower—was among the authors of the guidelines. Current plans call for propeller-driven wind turbines in the Freedom Tower to supply up to 20% of the building’s electricity.
