The Performance 2 project, in collaboration with Cerema and Aereco, addresses a crucial issue: the durability of Humidity controlled ventilation systems. These technologies, used to adjust airflow according to humidity in a building, must not only guarantee healthy air, but also remain efficient over the long term. A series of in-situ measurements were carried out over 2 years in buildings in Paris and Villeurbanne. The project explores their resistance to daily use by occupants after 15 years of use.
Humidity controlled ventilation: a sustainable solution
The principle behind humidity-controlled ventilation systems is simple and effective: modulate airflow according to humidity levels, thus guaranteeing ventilation adapted to the actual needs of the dwelling. This intelligent approach not only saves energy, but also improves Indoor Air Quality. The Performance 2 project focuses on analyzing this technology over time, based on indicators such as airflow, pressure, or even CO₂, and humidity levels.
Performance 2 project objectives
This project revolves around two key objectives:
- Develop a better scientific understanding of Humidity controlled ventilation systems, taking into account air quality and energy savings.
- Evaluate the durability of these systems under real-life conditions, by studying their evolution over time and in the face of everyday usage situations.
Project methodology and milestones
The project relies on a rigorous methodology, based on field surveys carried out over two winters in the buildings monitored by the initial Performance project. Here are the key stages:
- Compare the current performance of ventilation systems with that measured when the buildings were built over ten years ago. This study will show whether these technologies maintain their efficiency over the long term.
- Analyze the causes of variations in performance, whether due to technical factors, occupant use or maintenance.
- Evaluate occupant satisfaction during two IAQ campaigns, with the aim of understanding their needs and identifying areas for improvement so that these systems better meet everyday expectations.
- Defining evaluation criteria for systems intelligence, beyond energy performance, to include sustainability and user experience in the data.
Towards smarter, more sustainable buildings
The Performance 2 project offers a unique opportunity to better understand the durability of Humidity controlled ventilation systems under real-life conditions. By taking into account the results obtained, this project contributes to improving the design and maintenance management of ventilation systems in buildings, while guaranteeing optimum comfort for occupants and greater energy efficiency. In a world where housing is becoming increasingly intelligent, the durability and performance of ventilation systems are crucial to meeting the requirements of new building standards. The Performance 2 project is fully in line with this sustainable innovation approach, offering concrete solutions for the future of intelligent buildings.
