Urban Energy Research
Research Focus    
The research on Urban Energy Systems centres on the interrelations between urban design, energy and climate with a strong focus on energy generation, distribution and consumption in the urban environment. It considers the implications of distributed energy provision solutions as well as the user acceptance of such systems. This also includes research on energy efficiency measures and the integration of renewable and sustainable energy technologies into buildings and the urban built environment. Recent work has focused on the potentials of hydrogen systems in a future energy system, looking at an integration over several infrastructure sectors, spanning electrical grid management, hydrogen based mobility and municipal waste water treatment.

Research Themes
The following seven key research themes are derived from the research focus given above:
  • Energy systems and energy flows in the urban environment,
  • Hydrogen systems in a changing energy market,
  • Integration of renewable energy and storage systems into buildings and the urban environment,
  • Weather data for energy performance simulation,
  • Impacts of climate change on the urban environment and its infrastructure,
  • Energy efficiency in relation to urban design,
  • Energy efficiency in buildings / building refurbishment.
Besides these key research themes other research interests include:
  • Impacts of user behaviour on energy consumption,
  • Thermal comfort studies,
  • Energy performance certification and energy policy.

Research Projects
Current and completed research projects relate to the research themes listed above. Current work on the project LocalHy centres on the use of oxygen generated in the water electrolysis process for hydrogen production in the aeration basins of municipal sewage works. By this the fans usally required for aeration can be substituted, while at the same time achieving a more effective waste water treatment. Further to this, the overall implications of distributed hydrogen solutions installed on municipal sewage works for a future energy system spanning the sectors electricity generation, mobility and waste water treatment are being assessed. Complementing this work, the project H2-Well aims at taking the hydrogen economy to the next stage by showing its implementation potentials in the region between the rivers Main and Elbe.

Research within the project SusTherm that was completed in December 2016 dealt with investigating the potentials for thermally improving the Bhutanese building stock. The collaborative research project TestReal, which was looking at energy efficiency in relation to urban form, was completed in March 2015.

PhD Research
Current PhD research of the members of the group is related to the research project LocalHy. Completed PhD research of the group spans models for predicting the energy demand in the residential sector of a country. This work on energy modelling, which was conducted by Dr.-Ing. Aner Martinez Soto, looked at the transferability and accuracy of existing modelling approaches with the aim of developing and subsequently validating an enhanced prediction model that can be applied to countries worldwide. The results of this work, which has been completed in May 2017, have been presented at national and international conferences and published in the journal Energy and Buildings.
