Building for the Future
CARSI is a leader in the testing of building construction materials

Few places can compare to Winnipeg for dramatic changes in weather.
Over the course of a typical year, this city’s temperatures will swing from a frigid -30 C in winter to a blazing hot 30 C in summer.
Those wild swings from icy cold to sizzling heat combined with heavy rain and snow loads can take a toll, especially on the materials used in the construction of roads and buildings.
Which brings us to Ray Hoemsen and his colleagues at the Centre for Applied Research in Sustainable Development, also known as CARSI. The centre was conceived as a grass roots idea by the School of Construction and Engineering Technologies at Red River College.
Located on the Notre Dame Campus of Red River College, CARSI is one of places in Canada where builders can test materials for building envelopes – the outer walls of a building – to see how they hold up to the forces of Mother Nature.
To that end, the facility features a huge walk-in environmental testing chamber. Large enough for a car, the chamber has a barn-style door and is divided into two compartments, each of which can be independently controlled. On any given day, Hoemsen and his crew can turn the thermostat in either compartment down to – 40 C or up to 40 C; wall assemblies can be placed in a common wall opening and tested against temperature and humidity differentials.
