Intelligent Building Management Systems - IBMS specifically addresses the expanding requirements within industry & commerce for combining buildings energy management, security systems, fire alarm systems, CCTV, access control, etc, all into one control system utilising Intelligent Building Management Systems - IBMS.
EDS can design a system to bring together independent systems within a building to operate on one platform, so that one system can interact with another, being under the control of a main system from one central point of control usually a central PC with touch-screen display and voice activated recognition systems.
EDS utilise the latest technologically advanced operating systems to perform all control tasks, which can be linked to graphical displays or video imaging displays to enable the information to be acted upon much quicker than convention systems. Being controlled by one central unit makes controlling a large building simply a click of a button. Programming of the system is easily updated, usually by entering a few keystrokes into the system keyboard, or alternatively directly onto the system screen.
At the heart of every IBMS Intelligent Building Management Systems is sophisticated control and signalling equipment, working on distributed controller networks, which allow all data to be received and transmitted instantly to various parts of the building, to allow certain functions to be performed when certain conditions are met. This can be simply shutting down lighting, plant, air conditioning, movement of lifts, watering of plants, opening or closing of doors, etc. Being connected over distributed technology networks, reduces the cabling cost in a large building.
Huge cost saving can be made where all systems are designed to "talk" to each other providing management with greater control over the building coupled with increased safety and cost savings.
What is a Building Management System?
The BMS is a "stand alone" system that can calculate the pre-set requirements of the building and control the connected plant to meet those needs. Its inputs, such as temperature sensors and outputs, such as on/off signals are connected into outstations around the building. Programmes within these outstations use this information to decide the necessary level of applied control. The outstations are linked together and information can be passed from one to another. In addition a modem or interface can be connected to the system to allow remote access.
The level of control via the BMS is dependent upon the information received from its sensors and the way in which its programmes tell it to respond to that information. As well as offering a precise degree of control to its environment, it can be made to alarm on conditions that can't meet specification or warn of individual items of plant failure. Occupancy times for different areas are programmed into the Building Management System such that the plant is brought on and off to meet the occupier requirements. These times are often under optimum start control. This means that the heating plant is enabled, at a varying predetermined time, to ensure that the heated space is at the set desired temperature for the start of the day. The Building Management System therefore, based on the outside air temperature the space temperature and the building structure, determines the plant start time.
Managing multiple sites from one location offers the benefits that all sites can be observed at one time and comparisons can be drawn between each site for a cost performance basis, it's is also more economic than manned attendance at each site.
Why Have a Building Management System?
All Buildings have some form of mechanical and electrical services in order to provide the facilities necessary for maintaining a comfortable working environment. These services have to be controlled by some means to ensure, for example, that there is adequate hot water for sinks, that the hot water in the radiators is sufficient to keep an occupied space warm, that heating with ventilation and possibly cooling is provided to ensure comfort conditions wherever, irrespective of the number of occupants or individual preferences, ensure that security and safety systems are operational.
Basic controls take the form of manual switching, time clocks or temperature switches that provide the on and off signals for enabling pumps, fans or valves etc.
The purpose of a Building Management System (BMS) is to automate and take control of these operations in the most efficient way possible for building managers, operators and owners, within the constraints of the installed plant.
From schools to colleges, offices to tower blocks, factory units to production lines, significant benefits can be realised by the use of an EDS Intelligent Building Management System.
