Bioclimatic Architecture and Responsible Energy Consumption in Aquatic Centers


  • Thermodynamic dehumidification: use of an indirect reheat absorption machine to dehumidify the principal.
  • Free chilling (or natural cooling) taking advantage of the difference in temperature outside / inside and refused water to dehumidify in extra.
  • Valorisation of the “heat of rejection” coming from the machine: makes it possible to heat the pool, the water of the showers and the water of the basins.
    → Calorific energy gain exceeding 50%.
  • Supply study to choose the energy resource best suited to the local context of the swimming pool.

The “Dôme” of Vincennes

While the swimming pool is one of the most energy-intensive buildings, no regulation limits its consumption. There are, however, solutions to make it “passive“.

Saint Bonnet en Champsaur Swimmig Pool


  • The passive pool should receive maximum sunshine,
  • A strong insulation and airtightness to reduce the condensation and to be able to set up an efficient system intervening at the appropriate moments,
  • A transparent roof made of Texlon (composed of airbags, themselves composed of 3 or 4 layers of ETFE).
  • The thermal energy consumption is divided by 2.
  • The electricity consumption is reduced by 30% and we can also produce part of our electricity thanks to the transparent roof
  • The comfort of air and water is better in the halls and pools.
  • The consumption of “all-purpose” water in swimming pools can be divided by 2.
  • The olfactory comfort is better, the disinfection being done in part thanks to the ozone.
  • For the community, this allows the optimization of loads and costs and better conservation of buildings over time.
  • The packaged solution for small swimming pools can reduce up to 4 times the work time, while being cheaper and more efficient.
