Project description Built in 1961-1962, the Mathias-Thesen-Gymnasium school in Rostock-Reutershagen is now to be converted into an energy-plus school as part of a beacon project carried out within the framework of a research programme focusing on energy-efficient construction (EnOB). The Centre for Sustainable Energy Technology (zafh.net) has been given responsibility for optimizing the energy efficiency of the ventilation concept, which will involve both the analysis of energy flows within the school and the optimization of system control strategies. The brief includes the following core tasks: 1. The use of the mechanical ventilation system in a maximum of three selected classrooms equipped with an intensive monitoring network is to be optimized to the extent that the amount of electricity required in order to achieve an acceptable level of ambient air quality is minimized. Rooms are to be pre-conditioned using fixed-position heaters, with the ventilation system to be activated on a user-specific basis. 2. The ventilation system is to be controlled on the basis of timetabled room usage and specified ambient air parameters (measured using CO2 sensors) and/or ambient humidity. The optimized use of windows for ventilation purposes is also to be ensured. This might involve the use of a traffic light system which visualizes whether or the window-assisted ventilation of the classroom is a sensible, energy-efficient option based on current atmospheric conditions outside the building. 3. Weather forecasts are also to be incorporated into the ventilation control concept. This is especially sensible where night-time mechanical ventilation during the summer months is concerned, as mechanical ventilation should only be used for energy-intensive night-time cooling if high temperatures are forecast the next day. 4. The ventilation strategy for the tall, glazed buffer room needs to ensure as high a rate of heat release as possible. This requires the optimization of both how apertures are arranged and how and when they are opened.
