Nowadays the vast majority of buildings consume remarkable amount of energy and suppose to consume even more in near future. This process utilize both coal and natural gas, which affect the environment consequentially. Since the renewable energy sources promising, it is anticipated that electrical generation are still heading for using the fossil fuels, which consequently will develop the energy efficiency in commercial buildings as a critical issue. The main purpose of smart buildings is to diminish usage of energy, despite maintaining the fixed service. In this paper we examine the building’s design, depicting the basic role of actuation within buildings. We describe what is required for effective control and actuation how it can be accomplished, and show the results and findings from our own deployments in a commercial mixed-use building.
