Real estate company Cadillac Fairview Corporation has begun a $110m, multiyear revitalisation of the Toronto-Dominion (TD) Centre complex in Toronto, Canada.
The 46-storey tower is part of the TD centre complex which comprises five iconic black towers, built in 1969 and designed by architect Ludwig Mies van der Rohe.
The building envelope is made up of bronze-coloured curtain walls within a matte-black painted steel frame. The tower also features floor to ceiling windows.
Stage one of project will involve 5,676 windows being replaced with thermal double panes and a roller shade system ,which will offer better insulation and tinted bronze cover.
Progressive environmental standards and practices will also be employed to reduce energy consumption and waste.
The project intends to achieve the Leadership in Energy and Environmental Design (LEED) Gold certification for existing buildings this year.
