SEE - Stuttgart Energy Efficiency: Development and implementation of an energy-efficiency strategy for the entire city of Stuttgart

In the scope of the project »Stadt mit Energie-Effizienz (SEE Stuttgart)« Fraunhofer IBP focuses on performing comprehensive energy balance calculations for the entire City of Stuttgart (the state capital of Baden-Württemberg). Micro and macro analyses of the energy input and detailed consumption structures are conducted; all consumers (e.g. buildings, traffic, industrial processes etc.) are aggregated to obtain energy consumption data of city districts and the entire complex. In addition, several packages of measures are being developed to improve the energy performance, focusing on service processes. The aim is to reduce the energy demand of the City of Stuttgart by about 20 percent within the next 10 years.

 

Developing an energy concept for the urban energy transition

A macroscopic balance model was developed to document the current situation. This model provides the basis for an energy concept and serves as a monitoring tool. Moreover, a microscopic balance and strategy model was conceived for the private household sector. It is used as an agent-based simulation tool for analyzing the impact of potential measures, external effects and trends. Besides, optimization potentials were identified and estimated, from which options for appropriate action were derived for politicians and society. Finally, an 'Energy Road Map 2050', presenting different development scenarios, was prepared as a tool to support the municipality in decision-making.

Further, IBP experts have developed, provided and validated advisory services for households with regard to the energy use of buildings, mobility and household electricity, energy-relevant behavior and decisions. To support the retrofitting process, IBP experts also developed several services, ranging from initial consulting and quality assurance to contracting models and energy management.
