Energy efficiency of buildings may be improved using information provided by smart meters. They enable new services aiming at making the end-user aware of its energy consumption. Our vision is a neighbourhood of independent but co-operating buildings, with common aim to maximise their energy efficiency. Smart meters are the link between the buildings and the Neighbourhood Management System (NMS) which will control the community. The NMS will analyse the measurements, loads and available power in buildings and use simulation to forecast their behaviour to provide e.g. failure detection and load management. In this context a new concept has been developed. The concept illustrates an intelligent use of building energy information through a contest between several office buildings within a company. The idea is to combine both energy awareness and energy information benchmarking to create an incentive scheme for energy reduction in a tertiary environment.
