The $60 million Diamond Schmitt designed CANMET Materials Technology Laboratory at McMaster’s Innovation Park is a 165,000 sq. ft. environmentally sustainable research facility. The 3-storey structure supports research activities in the materials development and performance evaluation including pilot scale casting, rolling, forming and welding, corrosion, mechanical testing and micro-structure evaluations. As Building Envelope Consultants, RJC’s mandate was to provide innovative solutions to the facility’s energy-reducing goals. A 6,000 sq. ft. solar wall, high-performance thermal building envelope for the walls, foundations, roof, along with triple-glazing reduced heat to maximize energy efficiency and waste reduction. Exposed concrete slabs are featured throughout the building in an effort to significantly reduce finishes. The structural slabs incorporate radiant heating/cooling pipes to activate the thermal mass of the structure to reduce peak mechanical loads in the building. Recycled content was specified for all structural components including concrete, rebar, structural steel and metal deck. The CANMET-MTL is a leading-edge model of sustainable design in a laboratory setting.
