Energy-efficient renovation roadmaps for municipal districts


The objectives of the project build on the results of the predecessor project "3%" at various levels. The first step is to develop a crowd sourcing tool to analyse the readiness for implementation. In a next step, storage scenarios, a 3D city model and information from the CrowdSourcing tool will also be developed. A major goal is to improve the transfer in society and economy, e.g. by developing innovative business models and financing solutions.

Research Question

Starting from the previous project, the project is intended to work out the interplay between the financial, technical and social aspects and help single-family home owners to municipalities to achieve a higher rate of energy-related refurbishment.


The project is divided into five work packages (AP):

WP 4.1 focuses on the development of a crowd sourcing tool to analyse the willingness of private owners to implement the project. A scientifically independent and non-binding information platform is provided for this purpose.

In WP 4.2, a tool at the individual building level will be used to analyze energy-related implementation options for individual buildings and smaller groups of buildings and to support concrete implementation measures, e.g. for a condominium owners' association.

In WP 4.3 a monitoring concept is developed. This involves determining which data must be recorded and transmitted with which time resolution in order to create schedules for the operation of distributed systems and storage facilities. Furthermore, the monitoring data will be used to analyse tariff models in order to create incentives for grid-related behaviour of both consumers and renewable generation systems.

In WP 4.4, suitable locations for the integration of thermal and electrical storage solutions in combination with a SmartGrid for electricity and heat supply are found.

To improve the transfer of (technological) innovations to the economy and society, WP 4.5 will support the development of business models (e.g. for sector coupling, neighbourhood solutions) and develop appropriate financing solutions. Ideally, this process should support the creation of innovative start-ups.

Targeted results

With the knowledge gained, single-family home owners up to municipalities are to be supported in order to achieve a higher rate of refurbishment through their own investments and thus to achieve the federal government's energy saving goals.
