Short description
The “Kastanienallee am Teich” residential quarter, which is currently in the planning stage and will comprise 47 residential buildings, is intended to contribute to the climate-sensitive urban development of Darmstadt by providing the most sustainable and innovative energy supply possible. The centrally located excavation lake stores heat from solar radiation and groundwater, which in the future is to be made usable as environmental energy for the heating and hot water needs of the residents. For this purpose, heat energy from the deeper water layers of the lake is to be transferred to the brine of a cold local heating network by means of heat exchangers.
Within the F&E research project, the Chair of Hydraulic Engineering is investigating the extent to which sustainable heat can be extracted from the lake. In doing so, the lake habitat must not be adversely altered; this includes not only the stratification and mixing behavior but also sufficient regeneration of the water temperatures within the natural fluctuations. In addition, the warming of the lake due to climatic changes is anticipated in order to relieve the living organisms in and around the lake through heat extraction.
