Retrofit Project

An inexpensive insulating barrier reflects 24% more heat back into the building.

We also renovated all of the building's radiators.

The overhaul makes them better at keeping heat and air conditioning inside.

Refurbishment of the building's windows makes them up to 4x more efficient.

This process used more than 96% of the existing window glass.

All 6,514 windows were refurbished in a custom on-site processing center.

The ESB team devised a program to refurbish each of its 6,514 windows.
