Humidity-based DCV systems have been widely used in France for 35 years and are considered as a reference system, including for low-energy residential buildings. Indeed, most of the new residential buildings, which must be low-energy buildings to comply with the RT 2012 energy performance regulation, are equipped with such systems. Feedbacks from two long-term studies show the durability of the humidity sensitive components and show the robustness of this system to bad maintenance or use by occupants. The on-going Performance 2 project delivers the first results of a ten-year monitoring in thirty social housing apartments. In the context of the increasing awareness about smart ventilation, from these feedbacks, it seems very important consider the durability of the systems and its components (including the sensors) and the robustness of the systems to a lack of maintenance by occupants.
