Hannover, Germany
Hannover, the capital of the German federal state of Lower Saxony, has had a focus on energy efficiency since at least the mid-1990s when it approved a local climate protection programme.
Energy efficiency of buildings has already been a key consideration as around half of Hannover´s housing stock was built in the 1950s and 1960s to low energy retention standards. Hannover thus began to explore ways of financing modernization and retrofitting of buildings, and installing renewable energy capacity, such as solar water heating.
The CONCERTO approach
By involving local partners, politicians and stakeholders such as housing associations, energy suppliers, business, science and interested citizens, new standards should be set for the communities of tomorrow, and the experience gathered made available to other municipalities.
Working together, the climate protection aims will be achieved through practical measures in residential developments and applications of renewable energies. As supporting measures, energy saving and publicity campaigns to attract new investors are initiated. Training sessions support the construction measures and improve craft skills on site.
The demonstration projects were developed in the CONCERTO District' of Hainholz, Ahlem, Nordstadt, Herrenhausen, Limmer, Vinnhorst and Vahrenwald.
In Hannover the main focus is set on retrofitting of existing buildings and the implementation of renewable energies.
Use of Renewable Energy Sources
Low Carbon Technologies
Highlights
Hannover´s largest open-air swimming pool, Lister Bad, is now heated by solar energy, after northern Germany´s largest solar installation was put in place there. The solar heating is backed up by a gas-fired boiler.
