STM - Society in motion
The new bus body workshop February 18, 2009
Vegetation roof and walls to keep the building naturally cool in summer, highly energy-efficient boilers, low-emission materials and others made from recycled matter, all made in Québec… Every detail was well-thought out, making the STM’s new bus body workshop, where major maintenance work is conducted, a building that reflects the ideals of sustainable development.
Construction of the eco-friendly building was made possible through the support of Transports Québec. The building is also noteworthy for its harmonious integration in the surrounding residential neighbourhood. Proof that everyone wins when thinking green.
Green is trump for the STM’s new bus body workshop
> Vegetation Roof
From atop its 950 m2, the workshop’s green rooftop will also help control water run-off by cutting its amount by half, double the roof’s service life, counteract urban heat pockets and periods of smog, increase the building’s energy efficiency and promote bio-diversity.
> Solar Wall
The 500 m2 solar wall will help to heat the building naturally by making maximum use of the sun’s heat in winter. Energy-efficient, the wall could lead to annual savings of 24 700 m3 of natural gas.
> Vegetation-covered Walls
These vegetation barriers, designed to support vines and other plant, will act as a natural filter for air pollutants and as a sound buffer, while keeping the building cool in summer.
> Heat recovery
Installing high performance boilers will lead to a 10% increase in energy efficiency.
> Roller Compacted Concrete Pavements
More resistant than flexible pavement, this concrete mix is expected to last some 15 years longer than asphalt. It prevents collapsing pavement, potholes and ruts, while calming the effects of urban heat pockets. Highly resistant to abrasion, it is impervious to water, oil and fuel, a must for any eco-friendly bus body workshop.
> Green Spaces
Bicycle racks, rain water retention ponds landscaped with plant material, newly planted trees and recreational areas all add up to a workshop in harmony with its residential neighbourhood.
