Bioclimatic Architecture & Buildings

Bioclimatic design capitalizes on the characteristics of the site (climate, vegetation, topography and geology of the soil) in order to minimize the energy needs of the building and to create a more comfortable environment (hygro-thermal, acoustic, natural light) adapted to the ways and lifestyles of the inhabitants. In addition, special attention is paid to respect the existing landscape and integrate the building within it.

The positioning and orientation of the building as well as the interior distribution are calculated to profit as much as possible from the solar gain but not interfere with summer comfort.

But beyond this, the success of a bioclimatic design lies in the quality of coherence between: the options to take advantage of the place (1), the specifics of the casing (2) and additional technical solutions (3).

  • Solar gain, using natural ventilation flows, using the basement of the site;
  • The nature of walls, floors and roof, the characteristics of the insulation, woodwork and windows, as well as the positioning of inertial mass in the building;
  • Mechanical ventilation, ground-coupled heat exchanger, heating solution...
  • How is this different from a passive house ?

    For simplicity, we say that the approach of a classic Passive house seeks primarily to insulate the building from its environment in order to protect it from its nuisances and to rely on a highly technological ventilation system, while the so-called bioclimatic design, encourages direct contributions between the environment and the natural airflow. The objectives are more or less the same and finally, it is the bioclimatic context that dictates the final decision.
