Bernini Building Energy Upgrade (Verona)
Movicon 11 supervises special systems for distributed areas designed for bank and office use
The 17th century Bernini building prominently stands in the historical centre of Verona and is now head office to a banking institute after being renovated both in architecture and advanced energy management technology in 2010 focusing on energy consumptions and building/system synergy in particular.
SUPERVISION, MANAGEMENT AND CONTROL SYSTEM
The supervision system integrates into one hardware and software platform monitoring and controlling thermo, electrical, lighting systems with access control security, burglar and fire alarms fully monitored by TVCC.
All the systems use standard communication protocols so that they can be interfaced and communicate with each other easily.
The supervision system has been developed with the Movicon 11 Scada/HMI software platform designed
One of the general building upgrading project objectives was to install one unique system that controlled all plant engineering linked the thermo-mechanical and electrical systems, with the possibility of remote and local control management stations.
This building has three floors with a basement housing the central heating system. by Progea which has made it possible to integrate in one PC Server only, multiple communication drivers such as:
- Bacnet/IP or LonWorks: thermo mechanical systems (DAIKIN and SAUTER)
- CEIABI/IP: anti-intrusion and fire alarm systems
- FXPro or ModBus: illumination and technological alarm systems
- Modbus serial and TCP/IP: electric network Analyzors
- TCP/IP: TVCC systems
- technological alarm and light control
The illumination system management involves the use of lighting fixtures interfaced with DALI bus and regulated by means of luminosity sensors and presence detector sensors in conformity with the most recent European norms for energy system classification (EN 15232).
The following figure shows a detailed supervision system screen. This system is currently up and running in all areas with management entrusted to our company where the remote control station, energy management and alarm management are located.
The control system is regulated automatically and structured on different managerial levels:
– 1st Control Level (remote control users)
Individual users, using local commands, have the possibility to modify the main working parameters of each single light and internal unit such as ventilator speed, desired temperatures, airflow direction.
– 2nd Control level (centralized command)
Involves centralized control panels such as the Touch Controller with liquid crystal display, which allows the complete air conditioning system supervision, with start/stop functions by zone or for single groups, weekly timers, etc.
– 3rd Control Level (Building Management System)
This level is implemented with the light system conditioning/heating unit to command and regulate them. The use of a control system and lighting management system in function with presence detectors and preset lighting values is fundamental for optimizing power consumptions
CONTROL AND COMMAND USER INTERFACE
Simple and intuitive navigation of maps shown on graphical screen pages makes it possible to access all detailed information relating to each single light and air devices, HVAC, fire and burglar alarms are interfaced with BMS systems operating with BACnet, LON and Modbus protocols, through purpose-designed Gateways.
CALCULATING CONSUMPTION DISTRIBUTION AND COSTS
One of the project aims was to calculate and distribute electric and air conditioning system consumptions in the most flexible and efficient way possible while taking into account that the various areas may be used by different companies. In cases using air conditioning and heating systems, a connected monitor calculates and displays the quantity of electric energy used by pumps providing heat to monitored zones then each single air conditioning unit.
This system is designed mainly to facilitate interfacing with all smart building management system instrumentation for overall monitoring and controlling of all working statuses with prompt signaling of any malfunctioning if they should occur.
The validity and reliability of the designed solutions to contain energy costs were confirmed at the end of the last winter season when the first official consumption reports were issued with costs divided by the various users all thank to the supervision system installed.
