摘要:The world is changing rapidly heading to the future with quick intelligent steps. Adaptation of smart and responsible architecture that can cope with future demands is no more a choice. Nowadays; Smart buildings projects (SBP) is a new trend and very important worldwide type of projects. Smart buildings projects evolved during early 1980s and were called “Intelligent Buildings”. Since then; different definitions have been stated by many institutes and researchers, and the terminology “Intelligent Building” was then replaced with “Smart Building”. SBP in Egypt are rare; they don’t have clear description or specific definition. There is a lack of guidelines to establish a smart building in Egypt and lack of research work discussing SBP, their design, management system, life cycle costs, risks, etc. as well. This paper is concerned with determining the main challenges of SBP in Egypt through both: analysis of literature sources and analysis of some SBP internationaly and comparing them to SBP in Egypt. Finally; the results of the study were collected, analyzed and categorized and the key challenges of SBP in Egypt were determined and pointed out.
