Stoney Compressed Natural Gas Bus Storage and Transit Facility

Calgary Transit’s new fleet of compressed-natural-gas (CNG) buses have an equally new, nearly 500,000-square-foot storage and maintenance garage to call home. Staff can keep the fleet in top shape with 36 maintenance bays, two detail cleaning bays and on-site compressed-natural-gas fueling infrastructure. The facility also supports diesel bus operations to accommodate the transition from a diesel to CNG fleet.

The facility is the first CNG transit bus storage and maintenance garage delivered under a public-private-partnership model in North America, and the first project brought to market by The City of Calgary using this framework.

Building infrastructure for public transit is an investment in a cleaner city. Building on that sound principle, the project incorporated adjacent Wetland and Environmental Reserve areas into the site boundaries and added storm-water management ponds. Indoors, an innovative top-down ventilation system protects workers from noxious fumes.

The facility is only the second construction project in Canada to have received LEED v4 Gold certification, something the team achieved 13 months earlier than expected. Hundreds of Calgary transit operations staff work in a modern, LEED Gold facility, and Calgary residents and transit riders benefit from the new CNG fleet.

The awards committee of the Canadian Council for Public-Private Partnerships stated the Stoney Transit Facility is a “showpiece facility,” not only because it is the largest indoor compressed natural gas bus fueling complex in North America, but also because it is an “impressive example of infrastructure built and designed to incorporate sustainability.”
