Our solutions

Four areas of expertise, one signature: energ'ethical.

From diagnostic to commissioning, we support industrial clients (data centres, chemicals, energy…), commercial buildings and local authorities in decarbonising their cooling systems.

01 / 04

Energy audit

Full technical diagnostic of your refrigeration plants. On-site measurements, thermodynamic modelling, identification of savings opportunities and a costed decarbonisation roadmap.

  • Thermal & energy assessment
  • Refrigerant inventory & analysis
  • Prioritised action plan

Flagship project

−90%

electricity consumption on the cooling system

Reference

Cooling the CHU Sud Réunion hospital

Design and support of a very high-efficiency cooling system for the hospital complex, applying SWAC principles adapted to a tropical setting.

Outcome: a 90 % reduction in cooling-related electricity consumption, with no compromise on service quality or reliability, critical in a 24/7 hospital environment.
