At the University of Debrecen the department of Electrical Engineering and Mechatronics works in a so­ called Building Mechatronics Research Centre, where the researchers took the first steps of construction of an intelligent and sustainable building so the research infrastructure is configured. Several publications deal with the research centre from the building engineering approach, in this article we would like to describe briefly the applied measurement methods, which are principally conduce to monitor the energy consumption of the building to support the energy efficiency realization.
