The Empire State Building is my favorite building in the world, and now I have even more reason to love it. During a recent visit, I learned that over the last few years, the owners partnered with the Clinton Climate Initiative, NYSERDA, Johnson Controls and The Rocky Mountain Institute to do some major green renovations.

They made numerous improvements to the building’s outer shell and interior lighting and equipment to become more energy efficient. They also updated the chiller plants, and installed new air handlers (fans) that only run when needed.

This alone will reduce CO2 emissions by 50,000 metrics tons over the next 15 years. This, matched with tenant education and energy management systems, is saving the building $6,000 per day.
