With winter temperatures as low as -35°C in Regina, Saskatchewan, the football season is severely curtailed. Our concept for the city’s new open-air stadium will make playing and viewing more comfortable, increasing the length of time the arena can be used each year.
The Saskatchewan Roughriders, the local football team, currently plays at the Mosaic Stadium, an open arena built in 1910 that offers minimal weather protection. With the stadium showing its age, the City of Regina set out to build a replacement on a nearby city center site.
We were retained as owner’s engineer and architect for the project, responsible for the concept design, engineering, quantity surveying, and architecture. Working with local architects P3Architecture Partnership (and initially Pattern Design Ltd.), we developed the PSOS requirements for the CDN $278 million 31,000-seat project, which was undertaken as a public-private partnership (P3). We maintain an ongoing compliance monitoring role in behalf of the City, and are undertaking the detailed engineering design for the SRFC fit-out and training facilities, as well as the detailed design for the food and beverage facilities.
The spectacular new arena has an oval-shaped bowl, sunk into the ground for easy spectator access. An overarching roof will provide a lightweight solution with the outdoor feeling of the existing stadium — open over the playing field — while providing weather protection.
20°C reduction in winter chill
The roof is the key to the way the stadium will cope with extreme winter cold and adapt to summer heat. Our concept will significantly eliminate wind effects while allowing sun into the stadium. That can increase operative temperature inside the venue in winter by up to 20°C by wind mitigation and solar gain.
In the summer the roof will provide protection from the sun, with louvers beneath the roof encouraging through ventilation to keep spectators comfortable. Computational fluid dynamics has been used to model air movement in and around the stadium, allowing the design to be refined for optimum conditions for spectators.
Construction is expected to finish in time for the Roughriders’ 2017 season.
