The concepts and applications were then adapted, developed and modularised during the 1980s, enabling transferability of the technol
7、ogy and systems to the residential and commercial sectors.Intelligent buildings - control theory 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 s
8、ervices and manages the environment of the building concerned.Programmable Logic Controllers (PLCs) 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 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
11、m (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 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
15、ighting is required. (1) 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. (2) Time control: to switch on and off automatically in each zone to a preset schedule for light use. (3) Passi

(4) Light level monitoring: this consists of switching or dimming artificial lighting to maintain
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
21、usage, the figure is an impressive one.

Intelligent Buildings and Building Management Systems technologies contribute directly to the reduction in energy use, in commercial, industrial, institutional and domestic residential sectors.In short, Intelligent Buildings and suitably applied Build
23、ing Management Systems are good for the environment.Legislation and environmental standards; health and safety regulations; and global trends towards improving indoor air quality standards are all significant drivers of - and provide a continuous endorsement of the need for - Building Management Sys
24、tems and the Intelligent Buildings technologies. Government Initiatives around the world are also driving the development and adoption of Building Management Systems technologies. For example the UK Carbon Trust allows Enhanced Capital Allowance (ECA) to be offset against taxation on energy efficien
25、t systems, which enables savings of around 30% for all energy-related Building Management Systems and Intelligent Buildings equipment, and the associated installation and design costs. 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
31、ced lighting design is more than an electrical layout. 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
34、ding the distribution system of air into the workspaces, are the mechanical parts of buildings that affect thermal comfort. These systems must work together to provide building comfort. While not usually a part of the aesthetics of a building, they are critical to its operations and occupant satisfa
35、ction. The number one office complaint is that the workplace is too hot. Number two is that its too cold. 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
36、tion trying to adjust the comfort in their space. Improper temperature, humidity, ventilation, and indoor air quality can also have significant impacts on productivity and health. When we are thermally comfortable we work better, shop longer, relax, breathe easier, focus our attention better. In ord
