Engineering of building automation systems — State-of-the-art, deficits, approaches

Growing flexibility along with conversion, growing employee productivity and improvements in security are increasingly become the focus of interest in state-of-the-art buildings. Energy efficiency is a further essential aspect, which is associated with factors such as lower utilization costs. A modern and integrated building automation system is necessary to fulfill these demands. The engineering process provides the basis for developing such systems. However, today´s engineering process exhibits a number of shortcomings in the demands for implementing such systems. This paper focuses on the topic, describes today´s engineering process of building automation systems and identifies its deficits. It also reports on two approaches designed to largely eliminate the deficits. These approaches have been proved and tested in a reference project, which is also outlined.
