ELENA Piscines - A solution for optimizing energy consumption and air quality in aquatic centres

ELENA Piscines is an innovative solution, developed and patented, which makes it possible to reconcile in real-time comfort, air quality and "energy sobriety". ELENA Piscines can be easily installed on any existing HVAC system of public swimming pools or aquatic centres.

The technical operation of aquatic centres encompasses important technical and economic issues. The municipal swimming pool is the most energy-consuming building in a local community. To tackle this challenge, ELENA Piscines developed an HVAC solution for swimming pools with immediate and significant gains, thanks to the installation of a controller, compatible with the existing Air Handling Unit (AHU) and a few sensors placed in the pool hall (temperature, hygrometry, condensation). The principle is simple: The right amount of fresh air at the right time to guarantee excellent air quality (chloramine-free), optimal hygrothermal comfort, preservation of the equipment and building (humidity control), reduction of energy consumption due to air treatment (reduction of the electrical power of the air fans).
