Brézillon

Brézillon, an affiliate of Bouygues Bâtiment Ile-de France, is an industrial civil engineering, construction management and rehabilitation company located in Margny-lès-Compiègne, in the Picardy region of France. Founded in 1920 by André Brézillon, it became the first construction company in Picardy in 1945, joining the Bouygues group in 1993 as a general building division.

Brézillon was tasked with the design and construction of a building compatible with the ideas of the Grenelle de l’environnement, a French consortium of government, labor, industry and other related organizations with the goal of improving ecology, energy, sustainable development and territorial planning. An edict for the building was that it must be built with respect for environmental quality and safety, with the means to monitor and regulate facilities automatically in order to reduce energy costs.

The construction company, working with CR System and BETHIC, had a development time of 14 months, including finalizing electric work and an automated HVAC system. The selected building automation control was meant to tie into multiple procedures and equipment, including:

• Production of calories/kilocalories via two heat pumps (air/water)
• Production of high yield energy recovery (78%) via rotary-equipped CTA turbofan
• Terminal heat treatment via chilled beam induction and motorized air dampers
• Housing of local solar energy controls
• CO2 presence detection/rate metering and window controls
• Automatic monitoring and regulation
  • More than 2,400 checkpoints (CVCD/CFO/plumbing)
  • Control of energy performance: 102 electrical meters and hydraulic energy

GENESIS64 was installed to meet several of Brézillon’s requirements, including the ability to handle over 4,000 data points (including SAIA controls), integration with BACnet, Modbus and OPC communication infrastructures, and compatibility with Microsoft Windows^®. Our software adheres to the consortium’s environmental goals, provides diagnostics and support, and helps maintain comfortable conditions for occupants. Brézillon has found the software to be a user friendly, intuitive, open, scalable and comprehensive building automation management tool.

The customized graphical development through GENESIS64 allows non-technical users to be able to easily control their workspace environment. A panel-based PC at each office entrance allows occupants to control the temperature. With one click, a user can display current temperatures and can regulate any setpoints. In line with the company’s energy awareness initiatives, the system can also show which windows are open to help users decide whether additional air conditioning is needed. In addition, any supervisor-level changes are automatically reflected on the panel PCs.

Brézillon, CR System and BETHIC selected Mitsubishi Electric Iconics Digital Solutions for its ability to provide a Thin Client that was flexible in its integration with other building management system variables. The construction company received a user friendly, intuitive solution with high quality graphic user interface controls. Development with GENESIS64 was considered “strictly tailored to the customer needs”.

We were able to help Brézillon, CR System and BETHIC meet their Grenelle de l’environnement compatibility requirements. Future plans include expansion of the system into energy monitoring and preventive maintenance, with the goal of reducing energy consumption and greenhouse gas emissions.
