DEFINITION OF INTELLIGENT BUILDING : The Intelligent Building Institute has proposed: ´An intelligent building is one that provides a productive and cost-effective environment through optimization of its four basic elements structure, systems, services and management and the interrelationships between them. Intelligent buildings help business owners, property managers and occupants to realize their goals in the areas of cost, comfort, convenience, safety, long-term flexibility and marketability."

Intelligent Buildings are the buildings of 21st century. They combines innovations with skillful management to maximize the returns on investment. These buildings keep a watch over themselves and their own well being. They put off lights, shut down air conditioners, check the water storage tanks, recharge the central UPS in case of a power failure and switch on the alarm in case of fire.

Intelligent Buildings are equipped with robust telecommunication infrastructure, allowing for more efficient use of resources and increasing the comfort and security of its occupants. V

Building should know what is happening inside and immediately outside. Building should decide the most effective way of providing a convenient, comfortable and productive environment for its occupants. Building should respond as quickly as possible to the occupant·s requests. ´These attributes indicates the need for various technology and management systems. The successful integration of these systems will produce three dimensions of building intelligenceµ.

EXAMPLES OF HOW TECHNOLOGY HELPED TO PROVIDE ENERGY EFFICIENCY AND A SUPERIOR ENVIRONMENT à


  à

Dimmable fluorescent lighting integrated with sun blind control

Optimal lighting level and quality can be determined by the occupants.

Lighting control with motion sensors integrated with security

Reduces energy use and increases security

Natural and displacement ventilation.

More efficient and effective distribution of ventilation

Use of economizers for free cooling.

Energy efficiency.

Individual temperature and lighting control

Improved comfort is shown to improve productivity.

Radiant heating and cooling.

Improved comfort, reduced energy use

After hours control of lights and HVAC integrated with security

Improved security while reducing energy use

Monitoring of IAQ and contaminants. Improved comfort, safety, and productivity.

####-.# #!!# ÷   Access control restricts how and when people enter and/or exit an area. Your particular needs will determine how that is accomplished. Access Control Systems allow people or vehicles into a restricted area via identification through coded keys, magnetic cards, or biometric readers such as hand, face, voice, finger or retina readers. These systems are used in many businesses, hotels and apartment complexes.

- Systems can be programmed to allow certain users to enter specific areas only at certain times. Other users can be allowed to enter all locations at all times.

 ü Systems can automatically lock a door or gate each evening at a certain time and unlock it automatically at another time.

WORKING OF AN ACCESS CONTROL SYSTEMS 1.

2.

3.

First we need a barrier to prevent someone from entering or exiting, such as a locked door or gate. Next we need a way to determine who is trying to enter. A credential reader is used to read the information on a key or card, to register a combination of numbers entered on a pad or to identify some characteristic that the user has, such as a fingerprint the shape of a hand, a pattern in the eye, etc.

.

5.

6.

This identifier is sent to a controller that has stored a record of those identifiers that are authorized to enter the area. If the credential holder is authorized the controller unlocks the gate or door and the credential holder is allowed to enter. In many systems a record of all authorized and unauthorized credentials is stored in the system for future reference.

This type of access control is most commonly used in blocks of flats or apartments, where access to the front door needs to be controlled remotely. Communication between the internal phone and the outside speaker is established, before authorization to enter is granted

The newest technology in access control, biometric systems verify a person's identity, by unique physical characteristics, such as a fingerprint or retina.

SAFETY AND SURVEILLANCE Intelligence with respect to life safety in an intelligent building consists of the use of high technology to maximize the performance of fire alarm and security systems while at the same time minimizing costs. V Life safety factors involved in intelligent buildings include: V

¢ ¢ ¢ ¢ ¢ ¢ ¢

reduced manpower dependence, closed-circuit television, card access control, smoke detection, intrusion alarms, emergency control of elevators, doors and uninterruptible power supplies.
