The community of Oberschleißheim has been participating in the energy efficiency network of the Institute for Systemic Energy Consulting at the Landshut University of Applied Sciences for two years. After this phase of inventory inspection, data recording and detailed assessment, a catalog of measures with 81 improvement approaches has now been developed for the buildings of the municipality. While optimizations are to be carried out by the town hall during ongoing operations with little investment, more comprehensive proposals are further elaborated and pursued in the network.
This includes the approach that a photovoltaic system could be installed on the community center. According to the analysis, a standard system with an output of 38 kilowatts peak plus storage battery could cover 40 percent of the electricity needs of the central building. The community center currently consumes around 78,000 kilowatt hours per year. The network has calculated a payback period for the investment of twelve years.
The next approach is that a photovoltaic system in the sports hall on Jahnstrasse would be in the profit zone after eleven years. Depending on the location, a system output of 30 kilowatts peak was calculated there; the power consumption of the hall is 76,000 kilowatt hours. This means that the solar modules plus battery could cover 34 percent of electricity consumption.
The efficiency network sees several approaches for the self-sufficiency of the Berglwaldschule, including its own combined heat and power plant based on gas supply. In addition, another photovoltaic system could be installed on the west wing of the school, after a citizen solar system has been working on the main building for years. The proposals will now be further detailed and then submitted for a decision on a case-by-case basis.
