The building industry makes up a considerable fraction of world&amp / #8217 / s energy consumption. The adverse effects of a growing energy demand such as depletion in fossil fuel reserves and natural resources hassled the building industry to a search for new technologies that result in less energy consumption together with the maximum utilization of natural resources. Energy- and ecology-conscious European countries incorporated the well-being of occupants while conducting research on innovative technologies. In view of the fact that double-skin fa&ccedil / ades offer a healthy and comfortable milieu for the occupants and use natural resources hence consume less energy they became a promising invention for all concerns. The analysis of the performance of the double-skin fa&ccedil / ades and energy consumption is inconclusive at this time. However, based upon thermal performance analysis have been done so far, a double-skin fa&ccedil / ade perform better and provide some energy reduction, particularly on the heating side cycle, from a standard double glazed unit wall. The aim of this study was to examine the relationship between double-skin fa&ccedil / ades and building management systems in intelligent office buildings as they relate to energy efficiency issues thus to find out whether or not the integration of these systems into intelligent buildings provides optimization in energy performance and comfort conditions. The building for the case study, which is an intelligent office building incorporating a double-skin fa&ccedil / ade was selected as one that promises high comfort conditions for the occupants with low energy consumption. The working principles of integrated fa&ccedil / ade systems, together with their advantages and disadvantages were investigated by means of the case study. It was concluded that due to their high initial costs, these systems offer no real advantages for today. However with the inevitable exhaustion of fossil fuels that is foreseen for the future, these systems would become an innovative solution in terms of energy conservation.
