  1. 1. SAJID WARSI090105033E.I.E, 4th Yr.
  2. 2. BRIEF HISTORYThe high technology concept of intelligentbuilding systems was introduced in UnitedStates in early 1980’s.
  3. 3. In the early 1980s, several major technology trends were under way. the creation and services andemergence of the innovations enteredpersonal computer the telecom industry. marketplace
  4. 4. Smart Home Perspective ....a new kind of service delivery environment providingvalue to the consumer 21st Century Integration of comprehensive Living Environment 20th Century Functional System Integration makes life easier19th Cenrury Elementary tasks basedon Human Capability & Flexibility Infotainment Health care
  5. 5. Key DRIVER :Broadband Connectivity &Communicating DevicesBroadband connectivity -City Wide Broadband : Cable/DSL, -3GTelephony rollout starting (integrate the data) -WiFi deployment -Wimax is announced
  6. 6. This era also spawned the first real connection between real estatedevelopers and technology.
  7. 7. • Structured cabling systems, • Audio visual systems, building automation Some modest controllers with technological direct digital controladvancements in (DDC), buildings are: • Conditioned space for network equipment, • Access control systems, • Video surveillance.
  8. 8. The positive financial effects of integrated systems, Energy conservation, Greater systems functionality, The continuingThe drivers for smart evolution ofbuildings are :- technology. Increasing needs
  9. 9. WHAT IS SMART BUILDING? “a new generation of buildings Such a building was defined asthat almost think for themselves “a COMBINATION of two … called intelligent buildings.” technologies—old-fashioned building management and telecommunications.”
  10. 10. Building should know what ishappening insideand immediately outside. SMART BUILDING Building should decide the most effective way of providing a convenient, comfortable and productiveenvironment for its occupants.

  12. 12. AIM OF SMART BUILDINGS The technology allows us to operate the building more efficiently;and to differentiate to construct the and improve the buildings in a moremarketability of the efficient way, building. to provide to provide an productive and energy-efficient healthy spaces for and sustainable the occupants and environment, visitors, to provide a safe environment,
  13. 13. These systems include building A smart building involves the automation, lifeinstallation and use of advanced safety, telecommunications, user and integrated building systems, and facility technology systems. management systems. Smart buildings provide the most Smart buildings provide cost effective approach to the actionable information about a design and the deployment ofbuilding or space within a building building technology systems. The to allow the building owner or traditional way to design andoccupant to manage the building construct a building is to design, or space. install, and operate each system separately (Fig.1-1)
  14. 14. FIG.1.1 building systems.
  15. 15. The above process reduces the inefficiencies in the design and construction process saving timeSo, further developments were being done. and money.—allowing information anddata about the buildings operation to be used by multiple individualsoccupying and managing the building(Fig. 1.2)
  16. 16. FIG.1.2 INTEGRATED BUILDING SYSTEMS
  17. 17. Some instances A smart building, that is equipped with specialstructured wiring to enable For example: a switch appliances on or occupants to remotely homeowner on vacation off, control lighting, control or program an can use a Touchtone program a home theater or array of automated home phone to arm a home entertainment system, and electronic devices by security system, control perform many other tasks. entering a single temperature gauges, command.

  20. 20. HOW DOES IT WORK? Walls and ceilings will be embedded with sensors, and every aspect of a buildings performance and use will be metered and measured. Buildings will be fully Software tools will be used to interactive with the power automatically optimizegrid, and geospatial location building systems withoutsystems will be deployed for human intervention; every building asset. real-time information about the building that is relevant to their particular needs will be provided to occupants and building management.
  21. 21. DIFFERENCE BETWEEN ORDINARY BUILDINGS AND INTELLIGENT BUILDINGS.• Ordinary building, there will be • Intelligent building adjusts the different room conditions inside functional aspects such as depending on the changes in the lighting, ventilation, air environmental conditions. conditioning, etc. automatically• The cost of construction of with the changes in environmental Intelligent Building is very high as conditions controlled by computer. compared to an ordinary building. • In an Intelligent Building, the security system, communication system, etc. are coordinated and automatically controlled by computer work station where as in ordinary buildings there is no work station.
  22. 22. • But in case of ordinary • While planning an building, a building intelligent building, a service engineer and an building service engineer, architect is enough. an architect & hardware engineer is required.

  28. 28. TOPOLOGY Most building which connect high- automation level controllers with networks consist of lower-levela primary and secon controllers, dary bus and a user interface (also input/output devicesknown as a human interface device).
  29. 29. BACnet, Optical fiber, The primary and secondary ethernet, bus can be ARCNET, RS-232, RS-485 or awireless network.
  30. 30. Inputs and outputs are either analog or digital. 4-20 mA, 0-10 volt or Analog inputs are used platinum resistance to read a variablethermometer (resistance temperature measurement. detector), or wireless Examples sensors. are temperature, humidity and pressure s ensor which could be thermistor,
  31. 31. WORKINGA digital input indicates if a device is turnedon or not. Some examples of a digital inputwould be a 24VDC/AC signal, an airflow switch, or a volta-free relay contact(Dry Contact). Analog outputs control the speed or position of a device, such as a variable frequency drive, a I-P (current to pneumatics) transducer, or a valve or damper actuator. An example is a hot water valve opening up 25% to maintain a setpoint.
  32. 32. Digital outputs are usedto open and close relays and switches. Anexample would be to turn on the parking lights whena photocell indicates it is dark outside.
