Rooftop wind turbines becoming green status symbol in New York City

New York City developers are using rooftop wind turbines in an effort to attract buyers by highlighting a building’s green credentials.

A recent example is Pearson Court Square, a 197-unit apartment building in Queens which is adorned with three turbines resembling “huge carbon-fiber strands of DNA strung around a 10-foot mast,” according to the New York Times.

“We anticipated a lot of our tenants would be drawn to something different,” Ron Moelis, principal of L&M Development, the developer of Pearson Court Square, told the Times. The developer has been using sustainable design elements such as solar panels, insulated glass, and super-efficient boilers for many years. This was the developer’s first use of wind turbines.

While conventional turbines require a steady breeze of 10 miles per hour or more, helix-shaped turbines can capture winds from any direction and at lower speeds. The New York State Energy Research and Development Authority helped pay about half the $100,000 installation cost and will study the turbines’ efficacy.

Some green advocates bemoan this use of funds, however.

“A tiny windmill on a big building is just silly — it might as well be a pinwheel,” said Russell Unger, executive director of the Urban Green Council. “It’s a lovely idea, if people want to pay for it and test it out, but as far as return on investment goes, it’s a waste compared to more insulation and efficient building systems.”

New York City has two very large buildings dedicated to answering the 911 calls of its five boroughs. With more than 11 million emergency calls annually, it makes perfect sense. The second of these buildings, the Public Safety Answering Center II (PSAC II) is located on a nine-acre parcel of land in the Bronx. It’s an imposing 450,000 square-foot structure—a 240-foot-wide by 240-foot-tall cube. The gleaming aluminum cube risesthe equivalent of 24 stories from behind a grassy berm, projecting the unlikely impression that it might actually be floating. Like most visually striking structures, the building has drawn as much scorn as it has admiration.
