The Bluefactory Friborg-Freiburg AG will implement an exemplary concept at the location of its low-carbon innovation quarter in the middle of Freiburg from spring. It is supposed to control their energy and water flows. She developed it together with the energy supplier Groupe E and SINEF AG , which focuses on water, energy and industrial pipelines. According to a statement from Groupe E, the first phase of implementation is estimated at CHF 11 million. The concept can also be used in other quarters.
For this purpose, the supply networks to be created should optimally use the local natural resources – Pilettes source, geothermal energy, sun – and the facilities located in the vicinity such as water storage tanks, sewer pipes, cable ducts and the district heating network. All of this is aimed at a circular economy. It is intended to reduce the district's energetic and ecological footprint and promote biodiversity. Last but not least, users should also feel comfortable with it.
Groupe E will implement an energy concept based on the principle of heat exchange at low temperatures. The thermal energy comes directly from the ground, from the Pilettes source, as well as from rainwater and sewage. Peak loads are covered by the nearby Freiburg district heating system. Photovoltaic systems provide the daily electricity.
The concept for water management developed by SINEF AG enables the reintroduction of a more natural water cycle in the city center. Rainwater, for example, is collected and wastewater is cleaned on site. Collected water is used for flushing toilets, cleaning and irrigation. Urine-based fertilizer is produced on site.
