Abstract: In this paper, the Horizon-du-Lac school (in SainteMarthe-sur-le-Lac, near Montréal, Canada) is used as an archetype for data analytics, modelling and energy flexibility assessment for grid interaction. This school is a fully electric building with a geothermal heat pump system, several water-to-air heat pumps and an electrically heated thermal energy storage device. It has been in operation since 2017. A reduced order model of the classrooms is based on a grey box low-order resistance-capacitance (RC) thermal network along with its equivalent state-space formulation. The objective is to evaluate the potential of shifting the energy use from high to low price periods by adjusting setpoint profiles. Results show that the building can provide an energy flexibility of 49% during on-peak hours relative to a reference as-usual profile.
