Lower operating costs

It is inevitable that the announced increases in energy supply costs will translate into a significant rise in operating costs associated with heating and air conditioning.

New energy rating regulations in the building sector will also come with an obligation to improve performance over time. In this context, all building owners will have to carry out an impact analysis on their operating costs and plan re-engineering to mitigate this increase.

Our team of experts is best placed to meet this need. We offer simple-to-implement solutions with a guaranteed positive financial impact. This cost assurance of real reductions in operating costs enables our customers to make better investment decisions and sustainably increase the value of their current and future assets.

Proven measures for a risk-free project that delivers targeted results

Efficient electrification of heating systems and domestic hot water production
Heat recovery from exhaust air or wastewater
Profitable conversions to renewable energies (aerothermal, geothermal, solar)
Installation of variable frequency drives (VFDs) on fans and pumps
Demand-dependent modulation of ventilation rates (CO₂, occupancy)
Lighting conversion
Thermal storage integration
Controls upgrade, recommissioning

Digital twin

For a property owner, this tool becomes a strategic ally: it enables real-time visualization of equipment operating status, detecting performance drifts and anticipating maintenance needs before they turn into costly breakdowns.

Thanks to the integration of continuous data (sensors, operating history, energy consumption), the digital twin facilitates proactive decision-making, extends the service life of mechanical assets and helps maintain – or even improve – the building’s energy performance.

This is a key lever for achieving ESG objectives and optimizing the return on investment of HVAC infrastructures.

Our teams work in particular with Dybee technology from Quebec, to generate the following features and benefits:

Automated detection of anomalies or drops in energy efficiency.
Anticipating maintenance needs
Reduced operating costs: By optimizing equipment operation and preventing breakdowns, Dybee helps reduce maintenance and energy costs.
Informed decisions : The data provided enables managers to make decisions based on accurate, up-to-date information.

Performance monitoring and cost control

Keep total control over the energy performance of your installations.

Our advanced real-time monitoring solutions give you absolute transparency on the energy efficiency of your systems. Thanks to precise energy accounting and intuitive dashboards, Kolostat helps you to detect and correct deviations immediately, guaranteeing you lasting energy savings.

With our advanced technology, you can anticipate, control and continually optimize your energy costs.
