Fraena Kommune, Norway, are responsible for administration of schools.
In 2003, the decision was taken to invest in a computerized control and
monitoring system of the municipal properties.
From an ecological point of view the system was to maintain the external
controls for building and automation.
This makes Fraena Kommune one of the most future-oriented
administrations of schools. The BMS controller from AP is used.
The objectives of the investment in a computerized control and
monitoring system are several:
improve the efficiency of administration (all
staff have quick access to accurate and up to date information)
to save energy (taking control of undesirable
satisfied customers (detect errors before the
customer does, improved indoor climate, lower costs, etc.)
The requirement for the total system is that it
must be a fully open solution.
This means that from any laptop or stationary computer, you can operate
any building in a similar way (provided that you have the proper access
In addition, the overiding system has to be compatible with a strong
integration between the DUC systems.
All communication with DUC is via a fiber optic cable / broadband.
The number of DUC:s the overriding system can communicate with will be
157 and the number of physical I/O signals over 5000.
The number of communicating points will be over 20,000.
The system layout of the overriding system will consist of more than 5
PC´s connected in a very large fiber optic LAN.
In a facility of this size, where a large amount of data is collected,
analyzed and stored, accessibility it is extremely important.
Some critical parts of the site must be redundant.
Another very important factor for Fraena Kommune is that the overriding
system is scalable .i.e. you can start on small scale and then gradually
expand the facility. This is to avoid over-investment in the first stage.
After careful evaluation, AP:s BMS controller
with its overriding system was the system that best met with Fraena
The order was signed during the winter proving that AP's ideas and open
solutions for building automation are fully consistent with future
property managers´requirements in Fraena Kommune.
