Energy-Efficient Precast Concrete Wall and Floor Connections

Developing energy-efficient and durable floor and wall systems is critical to modern precast building construction, particularly with extreme weather conditions in Canada and the associated high costs of heating. This project addresses the structural performance of two components critical to energy efficiency of buildings as a result of their low thermal conductivity, namely double-wythe ultra-high performance concrete (UHPC) walls and cantilevered balcony component of precast concrete floors. Both components incorporate a thermal insulation system, which is sandwiched between the two wythes of the walls, and incorporated as a thermal break at the junction between the balcony and the rest of the concrete floor. Outcomes of this study will assist the industrial partner in introducing and promoting novel precast concrete components that are thermally efficient and structurally sound, as well as establishing a design guide, which is expected to benefit the Canadian construction sector.
