This project will develop a collective ‘Learning Energy System’ involving people, objects, data and machines. Central to this is a digital system designed to align human needs and comfort with building energy systems, with the aim of to reducing overall energy demand. This project differs from many energy reduction projects. The building user; as a sensor of conditions; as a driver of energy demand; as an individual; and as a collective, is at the heart of the ‘Learning Energy System’. Dynamic interactions between people and technology will be set up using innovative mobile applications.
