Using LEDs to efficiently illuminate paths and squares

Energy-efficient LED technology also facilitates targeted light distribution, making it suitable for lighting small areas. This further reduces the energy requirement while improving the lighting quality in cities.

Geothermal energy
Heating new construction areas with mine water

The goal of the GW-Ruhr project is to use the existing mining infrastructure in the Ruhr region for a more climate-friendly energy provision. The focus here is on recovering heat from mine water at former mining sites. Possible cooling demands will also be taken into account.

Multifunctional solar facades
Facade-integrated solar collectors with multiple uses

The ArKol research project aims to develop two innovative facade collectors from the initial concept to application readiness: a so-called strip collector that allows a considerable degree of freedom in terms of the geometry and material, and a solar thermal blind that can be inserted between...

Simulation of network hydraulics
Feeding renewable energy optimally into district heating networks

In this project, researchers want to find out how an increasing number of decentralised heat generators affect the network hydraulics and thermal cycling of existing district heating networks, and whether heat storage systems need to be retrofitted.

Sensor position affects energy requirements and indoor comfort

How does the sensor arrangement affect the energy requirements for heating and air-conditioning systems? And how can this impact be quantified under differing usage conditions? This research project intends to answer these questions based on coupled system and flow simulations in conjunction with...

Primary data collection- non-residential construction
Data on the energy efficiency of non-residential buildings in Germany

This project will systematically and comprehensively record non-residential buildings. In a step-by-step process, data for modernisation such as the structure and condition of the buildings, their energy efficiency as well as influencing factors for decision-making processes will be surveyed.

Financing models
Energy efficiency at universities through intracting

The research project is transferring the intracting funding model tested in municipalities to the special conditions that exist at universities. This is intended to support internal university energy management, develop economic energy-saving measures and relieve university budgets of energy costs.

Potentials analysed
Leveraging cross-sectoral potential for utilising surplus electricity

In this project, the various potential for the cross-sectoral exploitation of local and regional surplus electricity in north-eastern Germany is being investigated and quantified. Operating concepts and planning aids for power-to-X technologies are being developed for this purpose.
