Information and management system for central heating

The outdoor testing site of the Fraunhofer Institute of Building Physics IBP at Holzkirchen hosts two buildings that ae equal in construction and technical equipment and have the same orientation. These twin buidlings allow to perform comparative measurements on two different heating systems under identical boundary conditions. On the ground floor of each building living conditions of a real-life home environment has been created. Set-point temperatures have been specified for all rooms. There is mechanical ventilation with heat recovery but no window ventilation. Power consupmtion (gas mass, auxiliary energy) and actual temperature profiles (room and system temperatures) of both buildings are measured and compared to each other.
