The origins of Intelligent Buildings and Building Manag

The concepts and applications were then adapted, developed and modularised during the 1980s, enabling transferability of the technol

Later developments, in commercial and residential applications, were based on distributed-intelligence microprocessors. The use of these technolo

9、gies 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: 1 Time based - providing heating o

10、r lighting services, etc., only when required, and 2 Optimiser Parameter based - often utilising a representative aspect of the service, such as temperature for space heating or illuminance for lighting. Heating - time-based controlTime-based controls can be used to turn on and off the heating syste

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 con

12、trol: protection against freezing or frost protection generally involves running heating system pumps and boilers when external temperature reaches a set level (0C). Compensated systems: will control flow temperature in the heating circuit relative to external temperature. This will give a rise in t

13、he 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

14、to regulate output. Other methods can include thermostats, occupancy sensing PIRs (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 l

17、a light level measured by a photocell. Building management systems and intelligent buildings - energy savingsUntil 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 e

18、nergy 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 housebuilding sectors.For lighting

19、, 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 energ

20、y 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

For example the UK Carbon Trust allows Enhanced Capital Allowance (ECA) to be offset against taxation on energy efficien

Building management systems and intelligent buildings - market trendsCareful interpretation is required. In the UK,

26、 adoption of controls technologies into the new build and major refurbishment sectors is relatively high: Estimates a few years ago of the UK market for Building Management Control Systems for new build and major refurbishment, all sectors, suggest market adoption of (as at 1994 - Source UK1 An Appr

27、aisal of UK Energy RTD, ETSU -1994): Heating controls 70%. Hot water system controls 90%. Air conditioning controls 80%. However according to European Commission as many as 90% of all existing buildings have inapplicable or ineffective controls, many of which require complete refurbishment of contro

28、l systems.Moreover conventional control systems stop short of automated Intelligent Buildings full capabilities. A significant human element is required for optimal effective operation even if control systems correctly specified and installed.Given typical installations and equipment there is often

29、a difficulty for building occupants (residential) or managers (commercial) to operate them correctly. Usage and correct operation are vital for effective results.Education of users; improved systems-design user-friendliness, and the provision of relevant instructions and information are all critical

30、 to enable theory to translate into practice, and for potential effectiveness and savings to be realised. Building management systems and intelligent buildings - practical benefits Energy-effective systems balance a buildings electric light, daylight and mechanical systems for maximum benefit. Enhan

It must consider the needs and schedules of occupants, seasonal and climatic daylight changes, and its impact on the buildings mechanical systems.Lighting systemsAdding daylight to a building is one way to achieve an energy-effective design. Nat

32、ural daylight harvesting can make people happier, healthier, and more productive. And with the reduced need for electric light, a great deal of money can be saved on energy. Nearly every commercial building is a potential energy saving project, where the electric lighting systems can be designed to

33、be dimmed with the availability of daylight. Up to 75% of lighting energy consumption can be saved. In addition, by reducing electric lighting and minimizing solar heat gain, controlled lighting can also reduce a buildings air conditioning load. Mechanical systems The HVAC system and controls, inclu

While not usually a part of the aesthetics of a building, they are critical to its operations and occupant satisfa

Many people cope by adding fans, space heaters, covering up vents, complaining, conducting thermostat wars with their co-workers, or simply leaving the office. Occupants can be driven to distrac
