Some major green initiatives are taking place at the TD Centre these days. Work to achieve LEED Gold Certification at 77 King West and 79 Wellington West is currently underway. The most visible update is the new highly efficient windows that have been installed as seen here at 77 King West.

Many other initiatives are taking place including the addition of a grass roof atop the TD Banking Pavilion at the corner of King and Bay. Today's Photo Of The Day, taken by UrbanToronto forum member drum118, also shows the tower going black. Black in the sense it is getting a fresh coat of black paint. Our favourite towers in the city are soon going to look as good as ever.
