Intelligent buildings can be created through the use of smart materials.
These buildings would require structures capable of receiving and processing a multitude of complex data, preferably involving electrical systems. If such a structure remains dependent on a simple matter of stimulus and reaction, then a system cannot be described as intelligent.

The TRON Intelligent House designed in 1988 by Ken Sakamura in Nishi Azuba, Japan, is considered as the first intelligent building by today's standards. Costing 1 billion yen , the fully automated building contained a total of 380 computers, which were networked with the TRON architecture. All external information received from television, radio and telephone, and all internal information, exchanged via an audiovisual system, could be called up on monitors installed in every room.

Bill Gates had a smart house built, which, with the help of integral sensors and associated software, is capable of recognising people and, depending on user preferences, produces a change in the environment, so that when a person enters a room a favourite image is displayed on a monitor.
