STM, Canada

On January 6, 2014, the STM building (Société de transport de Montréal) opened to about 111 bus drivers and maintenance employees to the new Stinson bus garage in Quebec. This giant, two-story building has the capacity for up to 300 buses, including 100 articulated (double) buses.

Lemay Associés Architecture Firm designed the 165 million dollar building according to the principles of sustainable development. Everything possible has been attempted to ensure a LEED gold certification by creating a low impact development (Leadership in Energy and Environmental Design), to meet some of the highest industry standards. LEED certification recognizes the design, construction, and performance of high-performance green buildings.

A large part of the sustainable design of this building, a very large part in fact, comes from STM's massive green roof. In October 2013 green roofing company, Toits Vertige, installed over 80,000 square feet of Hydropack to make the STM building the largest green roof in Quebec, Canada.
