摘要
Over six billion people are expected to live in cities and surrounding regions by 2050. Consequently, in the near future, the autonomic and smart operation of cities may be a critical requirement to improve the economic, social, and environmental well-being of citizens. Smart urban technologies represent an important contribution to the sustainable development of cities, making smart cities a reality. In this sense, the energy sustainability of cities has become a global concern, bringing with it a wide range of research and technological challenges that affect many aspects of people%26apos;s lives. Because most of the human lifetime is spent indoors, buildings, which make up a city subsystem, require special attention. Indeed, buildings are the cornerstone in terms of power consumption and CO2 emissions on a global scale. In this paper, we analyze the role that buildings play in terms of their energy performance at city level and present an energy-efficient management system integrated in a building automation platform based on an Internet of Things approach. Occupants play a crucial role in the system%26apos;s operation to achieve energy efficient building performance, and any impact on self-sustainable smart cities will be a consequence of efficient user-centric smart building designs. Our proposal represents a user-centric smart solution as a contribution to the energy sustainability of modern cities. The building management platform has been deployed in a real (smart) building, in which a set of tests were carried out to assess different concerns involved in the building%26apos;s infrastructure management. The first stages of this experiment have already resulted in an energy saving in heating of about 20% at building level, which could translate into a reduction of 8% in the energy consumption of buildings at a European city level.
