The energy consumption in the operational phase of buildings is one of the major contributions to energy use in Europe. The improvement of energy efficiency only in the renewed stock (new and renovated buildings) is too slow considering the ambitious goal to improve the energy efficiency by 20 % before 2020.IntUBE will lead to increased life-cycle energy efficiency of the buildings without compromising the comfort or performance of the buildings by integrating the latest developments in ICT-field into Intelligent Building and Neighbourhood Management Systems (IBMS and NMS) and by presenting new ICT-enabled business models for energy-information related service provision.By using the existing building stock more efficiently with the help of the new tools and business models developed in IntUBE, the potential to reach the goal is considerably increased. The solutions will also be applicable to new buildings.The results of IntUBE will benefit many actors in the building sector like the owners, the users, the energy service providers, maintenance service providers, etc in form of well-performing buildings that use the natural resources (especially energy) optimally, resulting in less environmental effects and reduced life-cycle costs of energy.The IntUBE consortium consists of universities, research centres and companies from Southern to Northern Europe. They all have established dissemination channels, and the SMEs of the consortium will be able to extensively exploit the results in their business.
