Stratégies de contrôle local de la ventilation développement d'une plateforme numérique et expérimentale et expérimentale

Local control of ventilation in large buildings is considered to be a main issue in energy savings regarding the huge energy losses that are usually induced by such large volumes. An efficient ventilation system and the development of local control ventilation strategies could prevent large buildings from having an unsuited or overvalued ventilation and reduce significantly the energy consumption. Considering the issue of developing such strategies, both pollutant dispersal and heat transfer models, based on Computational Fluid Dynamics codes, have been developed in Science Buildings Laboratory (LASH) in Lyon. The models are used for numerical tests of established control ventilation strategies, while an added experimental device allows to perform experimental validation.
