In 2007, when the hospital was extended, the CTM system required complete redesign to integrate new equipment and renovate the existing tool, no longer up to date. For a group of buildings over a total area of 45,000 m², 500 beds and 1,500 employees, the stake was a major one, as it was monitoring and controlling all technical equipment used in:
- power distribution including generator sets, low voltage main panel, floor panels, power cutback/restoring priorities, etc.
- climatic comfort: heating and A/C
- air treatment unit (ATU)
- fluid distribution: water, oxygen, and medical gases
- lighting
The supervision architecture, designed and installed by INEO Picardie, is built around a server station and two client stations linked through Siemens S7 controllers, Sauter regulators and DIRIS measurement central units. Together they monitor electrical measurements, metering and energy management.
Topkapi: a strategic choice for the hospital centre
Easy configuration and ready to use functions prompted INEO to select Topkapi software platform, including:
- the time based programming function with the ‘Scheduler’ for lighting management
- easy installation of a client station, i.e. requiring a few minutes only and synchronized automatically with the server when modifying applications
- data archives management allowing to find logged data easily
- quality of AREAL’s technical support
Nicolas Renard, in charge of the electricity and climatic department, points out that ‘the tool is used daily’ for:
- reporting operating faults and diagnostic
- remote adjustment of temperatures and regulation settings
- monitoring power consumption meters and detecting drifts
In total about 80 recorders are configured, representing over 600 graphs plotted. To use this data systematically, the application is planned to be upgraded for the production of energy reports allowing to check and reduce consumptions by monitoring ambience temperatures and calory/frigory meters. This upgrade results from an energy effectiveness process already engaged, and at the centre of the users' concerns.
