Abstract: In cold and temperate climates, the increase of the buildings airtightness favoured a good energy performance but took part to the degradation of the indoor air quality (IAQ). Several methods exists to improve the IAQ and among them, the optimization of the ventilation strategy is one of the most efficient. This paper introduces a methodology combining a mathematical optimization technique and the building energy simulation in order to propose an optimal ventilation strategy monitored on two IAQ criteria while keeping in mind the energy efficiency aspect. In-situ feasibility of the ventilation system has also been taken into account through a smoothness objective of the ventilation profile calculation. Results allowed configuring efficiently the parameters of the ventilation algorithm. Moreover, each of them appeared to be robust according to the different climates.
