What are an intelligent buildings

and what are the applications of an RFID in construction?

What is an Intelligent Building?

A building that provides a responsive, effective and supportive environment within which an organisation can meet its performance objectives.

What Makes a Building Intelligent?

A building which can integrate it's various systems to effectively manage resources in a coordinated mode to maximise technical performance, investment & operating cost savings.

What is Radio Frequency Identification (RFID)?

A technology that can be used to:

Identify objects & store more information about the objects than barcodes.

Accurately locate & identify objects from a distance using RF signals.

Detect & read objects that are not in line of sight.

Modern RFID tags can store more memory (16-64KB) than barcodes (1-100Bytes)

What are the Components of RFID?

An antenna

A transceiver

A transponder (brain of the technology)

RFID Technology: Active Vs. Passive Tags

Passive Tags

Alert the tag to communicate when the reader's signal is detected by the tag.

Communicates without battery power.

Smaller size can easily fit on adhesive labels.

Derives power from reader's electromagnetic field.

Active Tags

Alert the RFID reader by sending out a signal.

Have their own power source.

Transmit a stronger signal and can be detected over a greater distance.

Are more expensive.

Have impact on size, cost, lifetime & maintenance.
