One of the nation’s most iconic structures recently got a facelift. As part of an ongoing energy efficiency and retrofit plan for the Empire State Building, 400 of the building’s existing standard lamps will be replaced by 1200 LED fixtures. The owners of the building have been working for some time on improving the structure’s energy efficiency with everything from high-tech windows to state-of-the-art HVAC systems.
By upgrading the Empire State Building’s exterior lighting, the owners expect to save up to 75% a year in annual energy costs, according a recent article in the New York Times. In fact, the lighting retrofit will generate enough energy savings to repay the multi-million-dollar project within six years.
These new fixtures are also expected to last up from three to six times longer than their incandescent counterparts. And the building will experience an aesthetic improvement as well: the new LED lamps will allow for a deeper color palette and the ability to change colors immediately, rather waiting for a crew of workers to manually install colored gel covers over the existing lamps. Right now the plan is to install the LED fixtures on the 72nd and 81st floors, along with the building’s mast (which is currently lit by fluorescent tubes).
Malkin Holdings, which owns the building, initially committed to improving the energy efficiency of the building back in 2006. Since that time, the owners have worked with the Rocky Mountain Institute to instigate a wide-scale energy efficiency retrofit at the facility.
“The building was state of the art when it was built,” Anthony E. Malkin, president of Malkin Holdings, told the New York Times, “and when we’re done with our retrofit, there will be no more technically advanced building.”
Here’s a rundown of our own coverage of the Empire State Building energy efficiency retrofit:
