The Empire State Building Goes Green

After 8 months of detailed planning, the Empire State Building is now undergoing a major sustainability retrofit. This project is projected to save 38% of the building's energy use and $4.4 million annually.

Heating, cooling, lighting, windows, and air handling are all getting an overhaul. Designing a new building to be efficient is difficult, retrofitting a building from the '30s is even more challenging.

What they achieve here can become a template for many other buildings and office spaces that want to improve energy performance and do so profitably.
