EPC with BMS and OptimiZ results in significant reduction in energy consumption
In 2019, CHR Sambre & Meuse signed an energy performance contract (EPC) with Equans to structurally reduce energy consumption and make the hospital future-proof. The use of a modern BMS and our OptimiZ detection system has optimised numerous installations. And with success, because the results show an average annual energy saving of 16%. Thanks to the close cooperation between the hospital and our technical teams, CHR Sambre & Meuse is now a model project in smart energy management within the healthcare sector.
Some key figures
How to save energy in a complex hospital?
With energy consumption comparable to that of more than 2,000 households, CHR Sambre & Meuse needed a more efficient approach. The challenge was clear: how to install a sustainable BMS and a system such as OptimiZ without disrupting patient comfort and safety?
“We had to find a solution that would ensure continuity and deliver real energy savings,” says Pascal Degimbe, who monitors consumption within the EPC.
BMS & OptimiZ as drivers for energy savings
Within the EPC, Equans modernised the entire energy infrastructure: optimisation of the combined heat and power system, modernisation of the boiler room, LED lighting, more efficient cooling machines and automatic power cut-off in operating theatres. In addition, solar carports were installed. Thanks to the BMS and OptimiZ, all data is collected and analysed centrally. We continuously monitor consumption via the Energis platform, in full compliance with IPMVP standards.
Strong performance well above EPC target
Thanks to BMS, OptimiZ and the measures within the EPC, CHR Sambre & Meuse achieves annual energy savings of 16%. Between 2021 and 2024, 5,000 MWh of electricity and 8,000 MWh of gas were saved. A total of 2,400 tonnes of CO₂ were avoided. The new hydrothermal installation was a crucial lever in this regard.
Frequently asked questions about building management systems

Yes. An energy performance contract can be applied in hospitals, offices, government buildings and industrial sites. BMS and OptimiZ are flexible and can be adapted to the complexity and needs of the building.
In most cases, the initial effects are visible within a few months because energy leaks are quickly detected and settings are optimised. The EPC model guarantees results.
OptimiZ detects anomalies that a traditional BMS often fails to notice, such as standby consumption or faulty sensors. Both major and minor problems are immediately identified, resulting in immediate energy savings.

Equans takes care of most of the technical follow-up. All that is expected of the customer is to contribute ideas about organisational habits and grant access to the installations. It is a genuine collaboration, but without placing a heavy burden on your employees.
Within an EPC, the risk lies with Equans. If the agreed reduction is not achieved, we will compensate for the difference. This makes the process financially secure for the customer.
The combination of BMS, OptimiZ and targeted technical improvements reduces gas and electricity consumption, automatically lowering your CO₂ emissions. For CHR Sambre & Meuse, this amounted to almost 2,400 tonnes of CO₂ in three years, an impact that is also achievable for other buildings.
Yes. Both systems can often be connected to existing installations. Major renovations are not always necessary; optimising what is already in place often yields strong results.
