Intelligent buildings design and building

management systems

Overview of 'intelligent buildings' and 'intelligent homes' technologies

The field of Intelligent Buildings, Intelligent Homes, Building Management Systems (BMS) encompasses an enormous variety of technologies, across commercial, industrial, institutional and domestic buildings, including energy management systems and building controls. The function of Building Management Systems is central to 'Intelligent Buildings' concepts; its purpose is to control, monitor and optimise building services, eg., lighting; heating; security, CCTV and alarm systems; access control; audio-visual and entertainment systems; ventilation, filtration and climate control, etc.; even time & attendance control and reporting (notably staff movement and availability). The potential within these concepts and the surrounding technology is vast, and our lives are changing from the effects of Intelligent Buildings developments on our living and working environments. The impact on facilities planning and facilities management is also potentially immense. Any facilities managers considering premises development or site relocation should also consider the opportunities presented by Intelligent Buildings technologies and concepts. This free summary article is contributed by Gary Mills, a leading UK-based expert in the field of Intelligent Buildings, Intelligent Homes, and Building Management Systems. The origins of Intelligent Buildings and Building Management Systems have roots in the industrial sector in the 1970's, from the systems and controls used to automate production processes and to optimise plant performances. The concepts and applications were then adapted, developed and modularised during the 1980's, enabling transferability of the technology and systems to the residential and commercial sectors.

The essence of Building Management Systems and Intelligent Buildings is in the control technologies, which allow integration, automation, and optimisation of all the services and equipment that provide services and manages the environment of the building concerned.

Programmable Logic Controllers (PLC's) formed the original basis of the control technologies.

Later developments, in commercial and residential applications, were based on 'distributed-intelligence microprocessors'.

The use of these technologies allows the optimisation of various site and building services, often yielding significant cost reductions and large energy savings. There are numerous methods by which building services within buildings can be controlled, falling broadly into two method types:

? Time based - providing heating or lighting services, etc., only when required,

and

? Optimiser Parameter based - often utilising a representative aspect of the

service, such as temperature for space heating or illuminance for lighting. Heating - time-based control

Time-based controls can be used to turn on and off the heating system (and/or water heating) at pre-selected periods (of the day, of the week, etc). Optimiser Parameters: whatever the conditions, the controls make sure the building reaches the desired temperature when occupancy starts.

Heating - optimiser parameter-based (temperature) control examples

? Temperature control: protection against freezing or frost protection generally

involves running heating system pumps and boilers when external temperature reaches a set level (0°C).

? Compensated systems: will control flow temperature in the heating circuit

relative to external temperature. This will give a rise in the circuit flow temperature when outside temperature drops.

? Thermostatic radiator valves: these sense space temperature in a room and

throttle the flow accordingly through the radiator or convector to which they are fitted.

? Proportional control: involves switching equipment on and off automatically to

regulate output.

? Other methods can include thermostats, occupancy sensing PIR's (passive

infra-red sensors), and manual user control. Lighting control methods

Different control systems exist, again time-based control and optimiser parameter-based where a level of illuminance or particular use of lighting is required.

? Zones: lights are switched on corresponding to the use and layout of the lit

areas, in order to avoid lighting a large area if only a small part of it needs light. ? Time control: to switch on and off automatically in each zone to a preset

schedule for light use.

? Passive Infra-Red (PIR) Occupancy sensing: In areas which are occupied

intermittently, occupancy sensors can be used to indicate whether or not anybody is present and switch the light on or off accordingly.

? Light level monitoring: this consists of switching or dimming artificial lighting

to maintain a light level measured by a photocell.

Building management systems and intelligent buildings - energy savings

Until recent years, energy efficiency has been a relatively low priority and low perceived opportunity to building owners and investors. However, with the dramatic increase and awareness of energy use concerns, and the advances in cost-effective technologies, energy efficiency is fast becoming part of real estate management, facilities management and operations strategy. The concepts are also now making significant inroads into the domestic residential house building sectors.

For lighting, energy savings can be up to 75% of the original circuit load, which represents 5% of the total energy consumption of the residential and commercial sectors.

Energy savings potential from water heating, cooling, or hot water production, can be up to 10%, which represents up to 7% of the total energy consumption of the domestic residential and commercial sectors.

Experiences from studies in Austria suggest potential heating and cooling energy savings are up to 30% in public buildings. Even allowing for the fact that buildings used in the study may have been those with particularly high energy usage, the figure is an impressive one.
