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.

    Another great story Ariel. I’m becoming quite the fan.

    This just goes to show that even a building that was built during the days of steam powered locomotives can find efficiencies. (Built in stages between 1871 and 1900, it wasn’t officially known as Grand Central Station until the later date).

    I can’t imagine any other place on earth that can capture and recycle five tons of newspaper.

    The roof of Grand Central Station is the Met Life building. The solar panels would have to be about 40 stories above Grand Central. :)

    I think they did a very good job to upgrade and ensure that the building is eco-friendly. Most countries these days only work on mega projects, which only concentrates on looks and extravaganza but they often forget that existing buildings with a touch of eco-thinking can be even better ;)
