It is increasingly common to work and live in buildings controlled by some system, the so-called Building Automation Systems, where to keep the levels of comfort and reduce energy consumption are very important requirements. These systems control from heating, ventilation, air conditioning, to lights intensity, with the goal of reducing energy costs and make the building occupants satisfied. However, these systems are usually proprietary and have high costs associated, due to the required equipment to deal with all the devices and the distinct communications. Therefore, our goal is to reduce reduce these costs, which is quite difficult due to the vast devices heterogeneity. In this dissertation, we implement a Building Automation System taking advantage of existing Internet of Things (IoT) solutions. Thus, this thesis explores how IoT solutions can fit adequately into the scenario of building automation. To validate our technological choices and evaluate the adequacy of the chosen middleware, we made use of an existing case study of a room with multiple components and an aquarium as a subsystem. We have compared different IoT approaches and their impact on the energy consumption and occupants comfort. The results obtained helped us to realise that in fact there are several aspects that can be enhanced in order to reduce energy consumption and maintain occupants’ comfort. An initial investment in the implementation of these systems may involve different types of equipment and development effort to achieve the desired solution. However in long term, it is worth the effort and initial investment on these systems since they can actually reduce the energy consumption and guarantee good conditions for the room occupants.
