Fraunhofer ISE is the largest solar research institute in Europe with around 1,100 employees. The institute's work ranges from research into the scientific and technical fundamentals of solar energy use to the development of prototypes and the execution of demonstration plants such as the solar hydrogen filling station at Heidenhofstraße.

Built in 2003, the Solar Info Center (SIC) – the competence centre for renewable energies and energy efficiency – offers 40 companies and institutions products and services for the local to the global energy transition. The platinum-certified SIC (LEED 2013) provides its tenants and visitors with an energy-efficient building with an exemplary energy concept at conventional costs. The concept is based on geothermal energy, photovoltaics and solar thermal energy. The solar casino, the conference centre, laboratory and office space offer a high quality of hospitality.

 

3 Faculty of Engineering at Albert-Ludwigs-Universität Freiburg

Georges-Köhler-Allee 101
Access: tram 4, stop "Technische Fakultät"

The aim is the complete ecological development of the campus of the 11th Faculty on the airfield. In the existing buildings, partial projects have already been implemented: LED lighting, highly efficient process cooling generation and groundwater cooling as well as results from the QuickCheck with Badenova at Tect4 with regard to energy flow analysis, plant efficiency and user behaviour. Ongoing research is being conducted on how the university can be supplied with energy more efficiently. Which measures will be implemented on campus in the future will depend on this research and other building decisions.

4 Solar Power Station Freiburg Trade Fair - FWTM GmbH & Co. KG

Europaplatz 1
Access: tram 4, stop "Technische Fakultät"
www.messe.freiburg.de

 

Since the expansion of the Freiburg trade fair in 2006, Freiburg's second largest solar system has now been installed on the flat roof of the four exhibition halls. This enables an annual electricity generation of about 650 kWp for the exhibition halls and the conference rooms. The lighting of the fair has also been switched to LED since 2014. The front building of the FWTM, which is currently under construction, will be linked to the planned district supply concept with waste heat.

 

5 Industrial waste heat for the Green Industry Park - Cerdia Produktions GmbH

Engesserstraße 8
Acces: tram 5, stop "Tullastraße"

Cerdia requires a large amount of electricity and heat for its production facilities. Initiated by the urban development in the area of the trade fair and airfield, the “old” idea of a waste heat network can now be implemented. From 2017, existing buildings and newly planned facilities will use waste heat for heating purposes – conventional heating centres and the use of fossil fuels are no longer needed. In addition to the trade fair, the front building of the FWTM, the new stadium of the SC Freiburg and the Autohaus Märtin, the model also offers an emission-free heat supply for further consumers – the potential savings are 1,100 t CO2 per year.

 

6 Combined heat and power plant Freiburg (WVK) – highly efficient generation of electricity and heat

Engesserstraße 8
Access: tram 5, stop "Tullastraße"

www.wvk.de

The idea for the WVK was born in the mid-90s in need of renovation. Driving forces were Cerdia and badenova. The simultaneous production of heat and electricity results in a significantly higher efficiency than in conventional power plants, which leads to a fuel saving of 30%. Combined heat and power technology, combined with natural gas as a fuel, reduces CO2 emissions by 50% compared to the nation's average – during full use of the WVK’s capacity, this amounts to 250,000 t of CO2 savings per year. In addition to the demand of Cerdia, electricity generation in the WVK covers up to 25% of the consumption of the city of Freiburg.

 

7 Electric mobility for IKEA customers - IKEA

Hermann-Mitsch-Straße 61
Access: tram 4, stop "Elsässer Straße", continue by bus 10, stop "IKEA"

www.IKEA.de/Freiburg

Since the end of 2013, the Freiburger VerkehrsAG (VAG) has carried out a pilot project for electromobility with badenova and IKEA Freiburg. Three "Schlauer Kombi" electric transporters are available free of charge to customers of the furniture store on presentation of a regional or day ticket of the VAG to transport large purchases home. The project was completed by the end of 2015 with 1,772 rental operations and 4.2t CO2 savings. IKEA Freiburg and Frei.mobil by VAG will continue the offer for two years.

 

9 Bio gas plant - RETERRA Freiburg GmbH

Bio gas plant RETERRA

Tullastraße 68
Access: tram 1, stop Paduaallee continue by bus 24, stop badenova

www.reterra.de

 

In the RETERRA biowaste fermentation plant, some 40,000 tonnes of biowaste from Freiburg, the district of Breisgau-Hochschwarzwald and from parts of the rural district of Lörrach are processed into renewable energy every year. The resulting biogas is mainly conducted – mixed with landfill gas from the former Eichelbuck landfill – via a gas pipeline to a combined heat and power plant in the district of Landwasser. As an example, for a period of one year around 4,900 households can be supplied with electricity and about 1,200 households with heat.

10 Combined Heat and Power Plant with Trigeneration - TDK-Micronas GmbH

Hans-Bunte-Straße 19
Access: bus 10, stop "Mooswaldallee"
www.micronas.com

With the CHP plant, TDK-Micronas relies on alternative energy generation and partly self-sufficient energy supply. It is thus possible to cover 30% of the electricity demand, 60% of the heat demand and 40% of the cooling requirements. The CHP plant consists of 2 generators with gas combustion engines each with 1,280 kW of electrical and 1,350 kW of thermal power. The electrical efficiency is over 43%, the overall efficiency over 90%. The highly efficient system runs over 8,300 hours per year without interruptions.

Mooswaldallee 1
Access: tram 5, stop "Gundelfinger Straße"

www.pfizer.de

More than 10,000 researchers and over 97,000 employees develop and distribute innovative medication and vaccines, as well as some of the world's most famous over-the-counter products such as ThermaCare, VitaSprint and Centrum.
The facility in Freiburg is one of the most modern plants in solid pharmeceutical production. Approximately 1,000 employees produce 6 billion tablets, capsules and dragees and 200 million packs per year in more than 3,000 different designs. The facility is also a pioneer in the field of environmental protection and sustainability in the pharmaceutical industry.

 

12 Energy Hill Eichelbuck - ASF Freiburg

Eichelbuckstraße
www.abfallwirtschaft-freiburg.de

Freiburg's largest solar installation, which was erected on the south side of the former Eichelbuck landfill in 2011, covers the annual electricity needs of about 1,000 households with a total output of 2.6 MWp. The combined energetic utilization of green waste in a biochar plant and a wood chip plant provides a new energy concept. It replaces the landfill gas that has been used to supply the waste disposal facilities on the landfill site (electricity and heat). The savings are about 2,500 t CO2 per year.
