Abstract

In course of the project “Creative Circle” a so called “energy transition cycle” in Eisenstadt is developed. This energy transition cycle aims to support the efficient use of the local renewable energy production. In addition, climate change adoption measures are implemented. The local district heating network, the sewage treatment plant and photovoltaic systems form the basis of the project. A large part of the population is currently supplied with heat from the district heating network that is mainly heated with biomass. Currently, a part of the heat goes unused with the wastewater to the sewage treatment plant. This is set to change in the future. The thermal energy in the wastewater will be integrated into the district heating network by using a heat pump. With regards to the electricity supply, a renewable energy community was established. The electricity demand of the heat pump as well as the electrical demand of the inhabitants of Eisenstadt can be partly covered with renewable energy from the energy community, at favorable tariffs. The energy from the energy transition cycle is also used for the environmentally friendly operation of a multifunctional Cooling Center, which provides a cool place to shelter from extreme heat free of charge and also functions as a social meeting point. As first part of the energy transition cycle, the Cooling Center located in the town house of Eisenstadt was completed in summer 2023. The foyer in the town hall was redesigned to make the stay as pleasant as possible and an innovative cooling system was implemented. The planning of the wastewater heat utilization at the sewage treatment plant was carried out in parallel. The integration of a heat pump in the sewage treatment plant shows considerable potential for reducing biomass and gas consumption and increasing the efficiency of the district heating network. However, the implementation of the project is not without its challenges. The technical design of the heat pump integration requires careful planning and coordination with the existing systems. Choosing the right size of heat pump, taking the biomass system into account, and increasing efficiency are complex tasks that need to be tackled carefully. Detailed planning and economic evaluations are currently being carried out.
