Where to start

Four services. Which one is for you?

Most chilled-water networks run at 7/12°C out of habit. Value Smart starts from your building to tell you what to do, and in what order.

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

02 / 04

Chiller refurbishment

Modernisation of existing equipment: switch to low-GWP refrigerants, cycle optimisation, control system upgrade. Performance restored, footprint reduced.

  • Refrigerant swap (HFC → HFO/CO₂)
  • Refrigeration cycle optimisation
  • Control system upgrade

03 / 04

SWAC & ocean energy

Sea Water Air Conditioning: cooling with deep sea water. Our historical expertise: design of thermal loops tapping the ocean for coastal and island sites.

  • Thermal resource studies
  • SWAC loop design
  • Ocean energy integration

04 / 04

OTEC · Ocean thermal energy

Energy and cooling drawn from the ocean thermal gradient. Our R&D via the OTEC Lab: producing electricity, cooling and even desalinated fresh water from deep sea water.

  • Full-scale OTEC Lab simulator
  • 24/7 decarbonised electricity
  • Desalinated fresh water as a by-product

How it works

Three steps, from first call to commissioning.

  1. Diagnosis

    Value Smart or an on-site audit: we read the regime actually in use and quantify the savings potential.

  2. Study

    We compare solutions for the same cooling demand, on whole-life cost and emissions, and size the best one.

  3. Delivery and control

    Refurbishment, SWAC or a new plant: design, works supervision, then setpoint control over time.

CHU Sud Réunion, système de climatisation
Flagship project

−90%

target for 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.

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