As building control systems continue to embrace state-of-the-art computer technology, more and more is heard about the use of "artificial intelligence" in building control. Programmable controllers, which are the basis of most building control systems, are considered to be one of the earliest artificial take based on a set of "If/Then" roles.

With this background in AI, it is not surprising that building control systems continue to utilize many developnlents coming out of AI research. This article will discuss the use of AI tectniques in building control systems.
