Pilot Projects for Energy Efficient Cities

Pilot projects are to show how energy efficiency in communities can be improved via intelligent use and networking of innovative technologies, planning and management methods. The EnEff:Stadt research initiative identifies assessment criteria and concepts as well as planning aids for municipalities and other actors, such as the housing industry and public utilities. In the context of the initiative, exergetically and economically optimised combinations of measures are developed for defined quarters. The implementation of these measures acts as an example and their effects are measured.The research is carried out in typical housing schemes. Development results are tested and assessed in typical city quarters. At the same time, the realisation of energy concepts and their monitoring and measurement is intended to implement the concept of integral planning. The aim is a minimum 30 percent reduction in primary energy use in the entire quarter through consistent application of new technologies and intelligent planning. The transfer of research and development results will provide the specific expertise needed to meet the urban development challenges of the future.

Model city district refurbishment: Weingarten West, Freiburg

The planning, implementation and measurement-based analysis of the energy-oriented refurbishment of the Freiburg city district Weingarten West is all being realised with the goal of a 30% reduction of primary energy consumption. The passive-house-standard refurbishment is to be demonstrated with the example of a 16-storey high-rise building. One key objective is stronger networking of the parties involved: building society, energy supplier and tenants.

Integrated Neighbourhood Energy Concept, Karlsruhe-Rintheim

Based on a neighbourhood energy concept, a local heating network – supplied by a cogeneration system and industrial waste heat - was set up to renovate the buildings for maximum economic effect. Subsequent operation is monitored continuously. In addition to innovations in building conceptual design, building services equipment, measurement and control technology as well as tenant communication, this project will be the first to implement a low-ex approach for an entire neighbourhood.

A former military base on its way to a zero energy city

As part of the energy concept for the Bad Aibling park grounds, the systematic conversion of the former military base aims to set the standard for exemplary conversion projects. The ultimate target of the planned development towards greater energy efficiency is to become a zero energy city.

Ecological settlement development in Kassel-Oberzwehren

A new residential complex combining high urban development and architectural quality with the implementation of innovative energy solutions will be built on the grounds of the former Horticultural Teaching and Experimental Institute of the University of Kassel in the Oberzwehren district.

Refurbishment and CO2-neutral heat supply to a 1950’s residential complex

Low energy refurbishment of a 1950's terraced block of flats in Munich-Haidhausen is to achieve a primary energy requirement for heating and domestic water heating at least 50% below the permitted value for a new building. The residual heat requirement is to be generated CO2-neutrally from renewable energy sources.
