Solar district heating system with power-to-heat

District heating system with heat supply from central solar collectors, industrial waste heat, heating centre, heat pump, and with short-term and seasonal thermal storage. Source of the heat pump is the saisonal storage. Excess power from PV and wind turbines is used to operate the heat pump.

Solar heat in smart cities

List of the main advantages of solar heat: it is emission-free and 100% renewable, it increases the energy security, the price is affordable and remains stable for at least 20 years, it replaces imported fueld and provide new jobs.

Pit thermal energy storage in Dronninglund (DK)

The pit thermal energy storage of 60,000 m3 in Dronninglund, Denmark, stores heat coming from a solar thermal field and a heat pump.

Diagram of the Flexible Sector Coupling model.

The electric energy system is composed of the sectors electricity, mobility and heat. Generated electricity is directed to the sectors mobility and heat along the pathways thermal energy, fuels and electricity.

IEA ES Task 45 experts alongside the Hechingen pit thermal energy storage

The pit storage in Hechingen, Germany, i already dug out. It will be finished and connected to the district heating system of Hechingen in 2025.

The former School at Kinkplatz at Night

Helmut Richter's school at Kinkplatz serves as a demonstration project for the GreenTech-Renovation exploratory project, as this building is a prime example of how topics can be dealt with in terms of sensible energy renovation.

Benefits of energy-efficient refurbishment using the example of the school at Kinkplatz

The transferability of the project helps to accelerate the renovation wave and focuses particularly on difficult buildings with high energy consumption. The strategies and findings from GreenTech-Renovation can be transferred to all buildings dating from the last 70 years with high proportions of glass and with intelligent adaptations even further.

Greening concept of the School at Kinkplatz

In addition to the climate and energy concept and the utilisation concept, effective synergies are created with greening measures on the façade, on the roof and in the interior. With innovative and coordinated integration of vegetation, the performance potential of building optimisation and energy measures can be increased.

Vertical farming concept for the School at Kinkplatz

During the exploratory project, the idea arose to use the school at Kinkplatz as a training centre for future urban farmers or vertical farmers. Special significance is attributed to the possibility of seeing food production as a central component of an overarching typological further development of the existing building as a training centre for urban vertical farming. This gives the school at Kinkplatz a unique selling point worldwide.

Neighborhood garden plan

Within the framework of a building association consisting of about 6-8 properties, the existing gardens could be interconnected to form a neighborhood garden in which countless design and usage possibilities of the green center could be realized. Here is an example with swimming pond
