The intervention concerned the first phase of a comprehensive energy optimization project, focused on the boiler room and gas distribution system of the site. The objective was to modernize the thermal management of a facility comprising three boiler rooms and four substations, requiring precise coordination of the hydraulic circuits. Therefore, the first phase of the project was structured around:

- The installation of three-way hydraulic valves to ensure precise regulation of flow rates and temperatures.

- The instrumentation of the circuits with surface-mounted probes positioned on the supply and return lines of the primary circuit, as well as on each secondary circuit, to enable tailored regulation.

- The intervention was carried out in several stages, ensuring the continuity of site operations and the safety of existing installations.

The main challenge was to deploy a high-performance control infrastructure across a multi-site boiler room, while simultaneously preparing the groundwork for subsequent phases of energy optimization.

We implemented a hydraulic regulation and thermal control infrastructure tailored to the site's specific characteristics:

- Installation of 3-way hydraulic valves enabling precise flow modulation and stable regulation of the heating circuits.

- Deployment of surface-mounted sensors on the supply and return lines of the primary circuit, providing reliable measurement of temperature variations and a calculation basis for regulation.

- Equipping each secondary circuit with dedicated sensors to ensure individualized and optimized temperature control by zone.

- Preparation of the technical architecture for future integration of the building management system (BMS) and advanced energy monitoring functionalities.
