Intelligent building research: a review

Within the last two decades, substantial amount of literature on intelligent building has been generated. However, there is a lack of systematic review of existing research efforts and achievements. A comprehensive review on existing research provides great benefits to identify where more efforts are needed and therefore the future research directions. For this purpose, this paper reviews the literature related to the subject area of intelligent building. Our review indicates that previous research efforts have dealt mainly with three research aspects including advanced and innovative intelligent technologies research, performance evaluation methodologies and investment evaluation analysis. It is also identified that among the three research aspects, relatively less literature has been found addressing the issues of investment evaluation of intelligent buildings. Based on a comprehensive literature review, the paper also summarizes a few future research directions, which are useful to researchers working in this important area.
