It must consider the needs and schedules of occupants, seasonal and climatic daylight changes, and its impact on the building39。 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 Systems 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 efficient systems, which enables savings of around 30% for all energyrelated 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, 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 Appraisal of UK Energy RTD, ETSU 1994):l Heating controls 70%.l Hot water system controls 90%.l 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 plete refurbishment of control 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 a difficulty for building occupants (residential) or managers (mercial) to operate them correctly. Usage and correct operation are vital for effective results.Education of users。 Eastern European Countries GOPA) Building management systems and intelligent buildings environmental and greenhouse gas benefitsGreenhouse gas emission reductions depend on and correlate to reductions in energy use.Intelligent Buildings and Building Management Systems technologies contribute directly to the reduction in energy use, in mercial, industrial, institutional and domestic residential sectors.In short, Intelligent Buildings and suitably applied Building Management Systems are good for the environment.Legislation and environmental standards。C).l 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.l 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.l Proportional control: involves switching equipment on and off automatically to regulate output.l Other methods can include thermostats, occupancy sensing PIR39。distributedintelligence microprocessors39。s, enabling transferability of the technology and systems to the residential and mercial sectors.Intelligent buildings control theoryThe 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 (PLC39。 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 UKbased 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 197039。 ventilation, filtration and climate control, etc.。 access control。 heating。 concepts。 technologiesThe field of Intelligent Buildings, Intelligent Homes, Building Management Systems (BMS) enpasses an enormous variety of technologies, across mercial, industrial, institutional and domestic buildings, including energy management systems and building controls. The function of Building Management Systems is central to 39。 and 39。不管將來是什么樣的，四年的大學生活都會銘記于我心，為了那些人、那些事，我也一定會努力學習和工作，踏踏實實走好人生的每一步，不讓人生留下遺憾！參考文獻 [1] 劉云浩. 物聯(lián)網(wǎng)導論[M]. 北京: 科學出版社, 2010.
