Genatis offers a solution for natural ventilation in buildings, which is essential today. Apart from the fact that it allows air to be renewed, it is vital to be aware of the benefits for occupants and managers. By ensuring a supply of fresh, healthy air, this solution aims to guarantee good indoor air quality, thermal relief and contribute to thermal comfort in summer. When used correctly, it considerably limits the impact on the environment and significantly reduces energy costs.

Natural ventilation is governed by two physical principles:

  • Thermal draft
  • The aerodynamic pump

Indoor air can be 8 times more polluted than outdoor air.

The cause is a high concentration of chemical, biological and physical pollutants…

Guide to natural ventilation

This guide provides precise support for optimising ventilation management, which is essential for the well-being of occupants and complies with the RE2020 regulations.

Benefits & advantages

Health

On average, we spend 80% of our time indoors. Indoor air can be up to 8 times more polluted than outdoor air (Co2/VOC). From a health point of view, it’s vital to understand that ventilation helps prevent, or at least limit, the spread or appearance of viruses and allergens (which cause respiratory illnesses).

Economical

The use of natural ventilation not only cleans the indoor air, but also creates a gentle breeze that is pleasant for occupants. The use of fans or other appliances is thus delayed or even eliminated, resulting in real savings.

Security

The supply of fresh, healthy air helps to combat humidity in the indoor atmosphere, preventing premature deterioration of the building. As a result, indoor comfort and well-being are optimised.

Comfort

Natural ventilation makes no noise, unlike certain appliances (fans, etc.). This is a real comfort for the occupant, who is not subject to permanent hearing discomfort.

Environment

It is possible to combine efforts to reduce the ecological footprint with significant savings. Limit greenhouse gas emissions by reducing or eliminating the use of energy-guzzling appliances. This responsible behaviour leads to lower energy costs.

Natural ventilation & control

Natural ventilation, combined with advanced control techniques, plays a key role in the thermal management of buildings. By optimising the use of outside air, particularly through night cooling and free cooling, it is possible to reduce the demand for cooling during the day while maintaining optimum indoor comfort. These innovative methods not only make it possible to manage temperatures effectively, but also to promote a more sustainable and economical environment.

Optimisation of Natural Ventilation for the Tellier Brise-Soleil Site

This case study examines natural ventilation for Tellier Brise-Soleil ‘s new manufacturing site in Chemillé-en-Anjou (49).

When constructing a new building, it is crucial to study various elements in order to correctly dimension the project and provide recommendations. These studies are essential to guarantee the optimum performance of natural ventilation.
