Sustainable Design Guidelines Published for WTC Development


January 28, 2004
by Canadian Architect

The World Trade Center development team recently released guidelines that will help shape how the office buildings and retail space manage energy consumption while minimizing their impact on the citys environment. Hints of how the new standards may be applied are already evident at ground zeros first construction site, 7 World Trade Center, just north of the main redevelopment site. There, large diesel engines were fitted with powerful filters and switched to ultra-low-sulfur fuel to reduce air pollution. The program’s success helped lead to the adoption of a city law mandating low-sulfur fuel and high-efficiency filters in all public construction. At 7 World Trade Center, rainwater will be collected on the roof and stored in tanks for reuse in toilets or to irrigate a small park next to the site. Computers will control heating and lighting, and power to commercial tenants will be metered, which should encourage conservation. Janno Lieber of Silverstein Properties, the developer who holds the trade centers commercial lease, said environmental features accounted for 3 to 5 percent of the cost of constructing 7 World Trade Center. On the main redevelopment site, the Freedom Tower, a much larger building, will incorporate many of the same environmental features as 7 World Trade Center, and a few not put in effect there, such as propeller-driven wind turbines that will furnish up to 10 percent of the towers electricity.
