| ROOM CONTROL SYSTEM
National Bank of Slovakia (NBS) headquarters Bratislava
Customer:
Johnson
Controls Int´s Bratislava
Hardware equipment: LONWORKSTM modules for building automation from various
producers
Realisation
July
2001
Characteristics of the system:
Building of NBS has 32 above-ground storeys and 3 under-ground storeys
and belongs to the most modern one in the Europe in the category of intelligent buildings,
thanks to the conception and the extend of solution. All rooms, passages and the rooms of
special proposal are equipped by LON controllers to solve optimal light and temperature
comfort according to: calendar, two meteorological stations, working time, occupancy of
the room by very complex way. They can solve personal needs, too and whole system is
connected to central dispatching of the building. LON nodes of the system, which have
logical bindings, are for the proposal of:
- heating and cooling (Johnson Controls) - are bind to controllers of
electrical conveyors, valves of floor heating and valves of cooling ceilings
- control of electrical conveyers (GLAMOX) – built into electrical
conveyers
- control of lighting digital/analogue (GESYTECH)
- control of light sections (GESYTECH)
- control of jalousie/blind drives (REKO)
- room control panel (WEIDMUELLER) – solves for control of individual
units in the room or can control the room via pre-programmed scenarios
- multisensor (PIR, LUXmeter, IR port) (PHILIPS)
- sensing of two meteorological stations (GESYTECH)
- support units of LON net: routers, repeaters, link powers for LON BUS,
LON data distributors, net control interface (NCI) stations with ETHERNET/LON interfaces
Additional capabilities of the control system:
- monitoring and control of all units from PC dispatching
- automatic control of blinds or positioning of jalousies depending on sun
position, intensity of sunshine and wind-speed
- required temperature control by heating or cooling and switching off both
at opening the double facade window
- keeping of light comfort in the rooms
- amount of pre-programming parametrizable controllers are about 5400
- communication basis FTT and LPT
- open solution for next changes
