'TRAINING WEEK' MATERIALS
The City of Hannover will work with partners to develop a tailor-made training programme to be delivered over five days in Hannover in April 2012. The training will involve desk-based and site visit-based learning opportunities, and focus on providing participants with knowledge and practical solutions on how to overcome technical, as well as procedural, barriers to SEAP action implementation. Click here to access training week materials including the training manual and presentations in April 2012.
1. Introduction and background to climate change policy in Hannover
In order to understand the City of Hannover’s policy context and approach to embedding local renewable energy solutions this section sets out some background information.
Political decisions, as well as the commitment of people in political spheres play pivotal roles in implementing climate protection goals at local level.
Information on the overarching policy framework for the City of Hannover, including the national German regulatory context, is set out in the presentations below:
- Climate Alliance Hannover 2020 (stakeholder and involvement of citizens), including the 2012 Solar Compaign and the Hannover SEAP
- Current German Energy Saving Regulations and Buildings
- Local ecological standards in Hannover
The district of Kronsberg in Hannover, built for Expo 2000, is a sustainably designed new part of the city and incorporates a wide number of Hannover's climate change and energy standards.
The following presentation sets out more information on this examplar new community:
- Sustainable Urban Development, Hannover - Kronsberg#

2. Passive house standards and non-residential buildings
Low-energy, zero-energy, or plus-energy concepts in new buildings and redevelopments aer the core issues in implementing the climate protection stragegies.
The basic principle is to reduce the building's energy requirement to the max (by marking energy improvements or applying new-building standards), then to cover the remaining energy requierment by a share of renweable energy that is as high as possible.
The City of Hannover has decided to construct all new urban buildings and as many redevelopments as possible to a passive house standard. This standard was developed just under 20 years ago in Darmstady and has been tried and tested thousands of times since.
The first presentation (in two parts) in this section will give details on what data is required and how projects can be implmeneted to thios standard:
- Climate Protection Fund - proKlima:
- Part 1: The enercity fund
- Part 2: the proKlima subsidy programme
The second presentation sets out the expierneces and conclusions in Hannover from local passive house projects

3. Retrofitting existing homes
Construction of the new buildings in Germany (and in Hannover) is low compared with the enormous demand for energy improvements in existing buildings. Therefore, improving the current building stock is vitally important for climate protection.
Similar to many cities in Europe, Hannover has a variety of buildings from different time periods and architectural styles. In Hannover, they have allocated average energy consumption figures by grouping together similar building types. The first presentation in this section will provide an overview of how this has been implemented.
- Energy efficient retrofitting (including residential multi-occupancy buildings and change of use)
The second presentation will reiterate some of the technical framework conditions for Europe and Germany and will then deal ni depth with the implementation of the different kinds of renewable energies in an urban context.
- Implementing renewable energy in the city

4. Energy supply and changing to renewables
In Germany, advanced energy-supply concepts for the cities are closely linked to local suppliers and energy utility companies.
In this presentation, the local energy company, Sttadtwerke Hannover provides an overview of its company, its power plants, its strategies and approaches.
- Enercity 2012
- Annex to presentation: technical details on the biogas system used by enercity
Hannover is an ambitious city where climate change adaptation and mitigation are concerned. This second persentation sets out its future plans and strategies.

5. Awareness raising, compaigning, and networking
The best government or local authority strategies cannot be implemented without the involvement of its citizens.
The development and implementation of campaigns, providing information and advice, as well as ensuring permanent contacts for all major issues, are equally as important keys to the success of climate protection strategies.
In addition to the City of Hannover’s Climate Protection Bureau, which has been in existence for just under 20 years, the not-for-profit Hannover Region’s Climate Protection Agency was founded over ten years ago. Its responsibility is to pool all regional climate protection activities and to expand the role of climate protection as the growth engine in the City as well as Hannover Region. It informs companies and citizens in the Hannover Region about a wide range of topics. Together with its partners it implements projects and campaigns in the following area:
- Energy-saving construction
- Energy-efficiency improvements to buildings
- Replace heating
- Expanding solar energy
- Wood-fired heating
- Harnessing wind energy
- Saving electricity
- Combined heat and power
- Eco-friendly mobility
- Funding programmes
Individual compaigns and activities by the Climate Protection Agency have been set out in the presentations below:
- Climate Protection Agency – Hannover region
- The 'Start well-advised compaign' for Private House Owners
The presentation below sets out a pan-European initiative used in Hannover which is aimed at small and medium sized businesses, 'Ecoprofit'. This programme aims to improve partnership working between the private sector and local authorities through 'profitable environmental protection'
