Modellstadt 25+ - Lampertheim effizient


Background and aims of the project

Expanding renewable energies, including the necessary generation and transmission infrastructure, and implementing energy efficiency measures are the most important pillars of achieving the energy transition in Germany. Therefore, the overall aim of project “Model Town 25+ – Lampertheim Efficient” is to develop innovative, integrated concepts for medium-sized towns to economically realize their energy efficiency potential.

Project contents and structure

Analysis and modelling open to all technologies, using multi-agent systems and scenarios, go beyond technological options at the level of buildings and quarters and allow for an integrated assessment taking the entire town into consideration. Depending on the aim, the models provide solutions such as optimal costs, minimal emissions, maximum revenue etc. which have so far been missing when considering entire towns. Considering private households, trade, industry, electric mobility, energy-intensive public facilities (e.g. pools, schools) and their infrastructure (electricity, gas, water) holistically is likely to yield energy efficiency potentials that cannot be tapped by merely improving buildings and quarters. In doing so, all kinds of different ways to optimize energy supply and generating energy regionally are included in the analysis and integrated concepts of energy and heat supply are developed, e.g. cogeneration, fuel cell, heat pumps, electric vehicles, photovoltaics and solar thermal energy, insulation measures, storage, and demand side management.

In addition to cladding and building technology, user behaviour plays a decisive role in modelling. The ISB is therefore developing a user typology that takes different energy-usage behaviours into account and attempts to characterize users’ investment behaviour so that potential future investments in energy measures can be assessed more accurately.


The research project lasts three years. It is funded by the BMWi as part of the support focus “EnEff:Stadt” within the 6th energy research programme of the federal government and is supervised by Project Management Jülich. All three of the project partners are contributing funding of their own to realize the project, resulting in a total volume of about three million Euros.

It is important to the project partners to include investors, users and municipalities in the project in order to develop practical, optimized ancillary services and accompanying funding models for private, municipal and industrial clients. By validating and using these concepts on the south-Hessian model town Lampertheim, we are making sure that they can be transferred to other model towns.

Project partners

In addition to the Institute of Urban and Transport Planning, the EnergyEffizienz GmbH (project management), the Institute for High Voltage Technology (RWTH), the town of Lampertheim, and the subcontractors ENERGIERIED GmbH & Co. KG and Trianel GmbH are involved in the project.
