【正文】 technologies The 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。Intelligent Buildings39。 concepts。 its purpose is to control, monitor and optimise building services, eg., lighting。 heating。 security, CCTV and alarm systems。 access control。 audiovisual and entertainment systems。 ventilation, filtration and climate control, etc.。 even time amp。 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。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 198039。s, enabling transferability of the technology and systems to the residential and mercial 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 services and manages the environment of the building concerned. Programmable Logic Controllers (PLC39。s) formed the original basis of the control technologies. Later developments, in mercial and residential applications, were based on 39。distributedintelligence microprocessors39。. 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 陜西理工學院 畢業(yè)設計 第 28 頁 共 54 頁 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 timebased control Timebased controls can be used to turn on and off the heating system (and/or water heating) at preselected 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 parameterbased (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 (0176。 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 PIR39。s (passive infrared sensors), and manual user control. Lighting control methods Different control systems exist, again timebased control and optimiser parameterbased 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 InfraRed (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 陜西理工學院 畢業(yè)設計 第 29 頁 共 54 頁 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 costeffective technologies, energy efficiency is fast being 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, energy savings can be up to 75% of the original circuit load, which represents 5% of the total energy consumption of the residential and mercial 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 mercial sectors. Experiences from studies in Austria suggest potential heating and cooling energy savings are up to 30
