New York's Grand Central Station: A Model of Energy Efficiency?

grand central station

At first glance, the nearly hundred year old Grand Central Station doesn’t look particularly energy efficient—after all, the station does contain 60,000 lightbulbs. But New York City officials are doing their best to make sure the terminal sets an example for other public buildings in the city.

The Metropolitan Transit Authority (MTA) has replaced the 20,000 interior bulbs in the station with CFLs that look like the building’s original round bulbs. Additionally, the MTA is testing out CFLs for the building’s chandeliers— although finding bulbs that have the correct shape, color, and lighting appearance is a challenge. The bulb-replacement spree will save the MTA quite a bit of money—$100,000 a year, in fact.

And the bulbs aren’t the only part of Grand Central’s energy efficiency scheme. The building is equipped with a unique air-conditioning system that uses low-cost lithium bromide and steam running beneath the building. The air-conditioner is almost twice as efficient as conventional systems and is much cheaper.

The station also collects over five tons of paper each day as part of a newspaper recycling program.

While it is easy to point out other ways that Grand Central’s energy efficiency could be improved—with solar panels on the roof, for example—we have to remember that the MTA is severely limited by the station’s designation as a National Historic Landmark (meaning the organization needs to get approval for almost every change made to the building). So considering what it has to work with, I’d say that the MTA is performing admirably.

I don't like paywalls. You don't like paywalls. Who likes paywalls? Here at CleanTechnica, we implemented a limited paywall for a while, but it always felt wrong — and it was always tough to decide what we should put behind there. In theory, your most exclusive and best content goes behind a paywall. But then fewer people read it! We just don't like paywalls, and so we've decided to ditch ours. Unfortunately, the media business is still a tough, cut-throat business with tiny margins. It's a never-ending Olympic challenge to stay above water or even perhaps — gasp — grow. So ...
