Project Title:
Reduction of energy for the heating of buildings by adaption to spatially and temporally differentiated requirements
Abstract:
In industrial countries of the northern hemisphere heating of buildings contributes a lot to the entire energy consumption. In Germany it is estimated that the energy consumption for the heating of flats could be reduced by about 20 % if people would be more aware of energy cost and would behave more economically. There exists already a wide variety of techniques for automatic control of heating including means for the reduction of energy consumption. One of the most advanced technologies enables the automatic detection of the opening of windows (by wireless sensor networks), automatically causing the reduction of hot water flow to the heaters in the corresponding rooms. The following points seem to be essential for the practical success of technical means for the reduction of energy consumption by controlling heating: The heating must be differenciated in time and space. Different people in different rooms have different behavior and demand different heating schemes, that have to adapt itself to changing conditions and requirements. As far as possible, this adaption should be carried out automatically. Because a technical system in principle cannot exactly adapt to the wishes and the behavior of a person (i.e. cannot know if a person will leave a room for a short or long time), human beings should be able to influence the heating and thereby the energy consumption by themselves. Components of heating systems or independent technical means should inform people living and working in heated rooms about both actual energy consumption and saving potentials. At first in the master theses an overview on the different existing techniques for automatic heating control with energy saving procedures, for influencing the heating by persons and for increasing the saving potential should be elaborated. Furthermore the thesis should investigate and evaluate these techniques especially with respect to the following aspects: Practical experience with the systems, i.e. achieved savings of energy consumption, influence of the behavior of human beings on energy consumption, comparison of costs for the implementation of the different systems, comparison of maintenance costs, including the costs for battery management in the case of battery-powered sensors, evaluation of the practical effects of micro energy harvesting, e. g. for the supply of wireless sensors with electric energy.
