About

Within the topic of smart cities, we work on a common modelling of city energy systems, aiming at increasing the share of renewable energy sources, increasing efficiency, and still ensuring a stable and efficient energy system. Within the CITIES research center, my position is Deputy Center leader. My and my near colleagues research is focused on the question, whether buildings can play an active role in the stabilization of the energy system, e.g. through the utilization of buildings thermal mass for storage. Simulation models are basically able to answer this question, however simplifications for fast computing did probably ruin this ability. Hence actual research questions the dynamics of our simulation tools, with the goal of finding the tools that are able to simulate the behaviour of the thermal mass in buildings accurately with respect to the time aspects of flexibility (the ability to shift energy demand in time and space). Within the research project of EnergyLab Nordhavn, we are experimenting on the full scale city lab, developing and testing solutions to move energy between energy carriers, in time and space, developing user friendly energy optimization solutions and try them in full scale. We will carry out a large set of experiments in all parts of the energy system, from components to the grid, monitoring and documenting the results for analysis. We do innovation on basis of the above, spreading from integrated building design to component design and grid optimization, IT solutions, algorithms and also knowledge-based support for decision making within IEA EBC Annex 63 and 67. My personal research playground is defined in the Lyngby Smart Cities project within Videnbyen Lyngby, where the local actors across all organisation, Municipality, consultants, private companies, university, schools etc. develop our own Smart City in Lyngby, building on the facts that the city is growing rapidly, that we have a large demand for building renovation, we get a light train to the city and we have a huge hub of education with DTU as a main driver.
