Buildings account for about 35% of energy use in Sweden. Today methods exist for calculating energy use and to design the building envelope as well as building systems where current trends leads more and more towards energy efficient buildings. IEEB is a collaboration between Luleå University of Technology, Umeå University, Oulu University of Applied Science, Norut Narvik, industry partners, and society with the goal of increasing knowledge and developing new ways to produce energy-efficient buildings in cold climates.
Luleå University's contributions to IEEB project is about making energy measurements of existing buildings and connect it to the building's physical characteristics. The research will lead to improved methods for measurement through analyzing the energy performance of the building envelope independent of installation and residents. The method could be used by the constructors to impartially verify the quality of the delivered building envelope.
