With the targets for the Climate Action Plan 2050, the German government is pursuing ambitious plans. For the building sector, this means that a virtually climate-neutral building stock is to be achieved by 2050. The Federal Building Ministry has launched pilot projects, such as Efficiency Houses Plus in existing buildings, which are investigating ways to achieve this goal in a practical manner. By 2030, the political framework conditions should be designed in such a way that the requirements for a virtually climate-neutral building stock are already in place. The energy standard for the construction of new residential and non-residential buildings must be further developed by 2030. Likewise, from 2030, the energy-efficient refurbishment of buildings must largely fulfil the requirement of a virtually climate-neutral building stock.
To ensure that the necessary energy-efficient refurbishment and new construction measures are sustainable, the focus must be on holistic planning approaches that combine forward-looking architectural design and utilisation quality with energy-efficient measures. Special care must be taken with energy refurbishment measures to protect our building fabric that is worth preserving, including those that are not subject to protection under monument protection legislation. The diversity of façades must be protected.
For all buildings, whether new or old, the following applies: The compatibility with the building culture must be examined on a case-by-case basis, and various ecological, economic, technical and design solutions must be sought. Standardisation, shapelessness and arbitrariness should be avoided. They lead to a loss of identity-forming building culture.
Objectives: Extract from the fields of action
The Climate Action Plan is based on the guiding principle of achieving greenhouse gas neutrality by the middle of the century. For the year 2030, it reaffirms the overall target of a greenhouse gas reduction of at least 55 per cent compared to 1990, while at the same time breaking this overall target down into individual sectors for the first time. The plan thus provides clear guidance for all sectors.
Of central importance is the reorganisation of the Energy industry. Important steps have already been taken in this sector with the energy transition. Renewable electricity will also enable other sectors - such as transport - to move away from climate-damaging fossil fuels. Renewable energies will be further expanded and coal-fired power generation will be reduced accordingly. A new "Growth, Structural Change and Regional Development" commission is to develop a mix of instruments. This is intended to help the regions and sectors that are particularly affected by the structural change associated with the energy transition.
At Buildings there is a "roadmap for a virtually climate-neutral building stock". Buildings are particularly durable, which is why the course for 2050 must be set early on. The reduction should be 66-67 per cent by 2030. This will be achieved through ambitious new building standards, long-term refurbishment strategies and the gradual phasing out of fossil-fuelled heating systems.
The Transport sector will contribute 40 to 42 per cent to the 2030 climate target. A series of climate protection concepts will identify measures to achieve this, such as a climate protection concept for road transport. Alternative drive systems, local public transport, rail transport and cycling and walking will play an important role, as will a digitalisation strategy.
In the area of Industry the reduction should be 49 to 51 per cent. The German government will launch a research, development and market launch programme to reduce previously unavoidable industrial process emissions.
For land use and Forestrywhich are not included in the assessment of target fulfilment, the focus is on maintaining and improving the sink capacity of the forest. In addition, sustainable forest management and the associated use of wood, the preservation of permanent grassland, the protection of peat soils and the climate potential of natural forest development.

The construction of new solar power plants in Lower Saxony continues to grow strongly. In 2018, an increase of more than 72 percent was recorded compared to 2017. While the addition of new capacity in 2017 was 120 MW, around 208 megawatts were newly installed in 2018. This means that Lower Saxony currently has just under 4,000 MW of installed solar power capacity, according to the Climate Protection and Energy Agency of Lower Saxony (KEAN).
The very positive expansion figures of the last two years show that Lower Saxony has recognised the opportunities offered by solar power and has started to catch up with the southern German states. In addition to the nationwide pioneering role in wind energy with a good 11,000 MW of installed capacity, solar power has the potential to become another important source in the generation of electricity from renewable energies in Lower Saxony.
"Solar power is the ideal complement to wind power, as these two renewable energy sources peak at different times during the year," Lothar Nolte, Managing Director of the Climate Protection and Energy Agency of Lower Saxony, explains the effect. "While wind turbines turn fastest in autumn and winter, solar panels offer the greatest yield from spring to late summer."
Solar consultations also at an all-time high
The expansion figures are all the more remarkable because there are hardly any large-scale ground-mounted systems in Lower Saxony, and almost all systems are installed on private and commercial roofs. The interest in the use of solar power is also reflected in the increasing demand for solar consultations. Last year, more than 2,200 homeowners took advantage of "solar checks". The checks are offered jointly by KEAN, the Lower Saxony Consumer Advice Centre and regional partners. In addition, 124 companies received advice on the possibilities of solar energy generation and use.
There are many reasons for the growing interest in solar power: on the one hand, module prices have fallen significantly over the years, so that a kilowatt hour can be generated on a single-family home for around 10-12 cents. This makes self-consumption of electricity interesting, as the purchased electricity averages around 30 cents per kWh. On larger roof areas, such as on agricultural or commercial buildings, generation is even cheaper. Here, too, self-consumption is clearly more important than feeding electricity into the grid. "The desire for as much self-generation as possible, which creates at least a certain degree of independence, is another important motivation for building owners," explains Lothar Nolte.
The regional analysis shows that the expansion is developing well, especially in rural areas. The Emsland district is at the top of the list with 22 MW in 2018. If one relates the expansion to the number of inhabitants, the districts of Vechta and Nienburg come out on top. In urban areas, the expansion of solar power plants is significantly lower. In the view of the Climate Protection and Energy Agency of Lower Saxony, the reason lies in the far too complicated regulations for tenant electricity. "Many roof areas would be perfectly suitable, but the use of the electricity for tenants is made difficult with a bureaucratic bulwark," says Lothar Nolte. "There should be a consistent simplification here.

The city is to become cleaner and quieter: Under the heading "blue_village_Franklin", important future topics such as new mobility, energy efficiency, climate-optimised living or smart grids are being tested with the conversion of the former military area FRANKLIN. The SQUARE project, two model houses renovated according to the latest energy standards, and the electromobile bus lines 66 and 67 are part of this master plan. Franz Untersteller MdL, State Minister for the Environment, Climate and Energy Management, visited the two model projects in the new urban quarter on Tuesday, 4 August, as part of his summer tour "Environmental Future".
"With SQUARE, the city of Mannheim and the Mannheim housing association are showing a way to design climate- and energy-optimised living in existing buildings," said the Environment Minister during his visit. "It is impressive to see what has been implemented here in terms of building refurbishment, electromobility and smart grids. And it will be exciting to evaluate the results of this model project and make them usable for other projects."
Lord Mayor Dr. Peter Kurz explains: "With Franklin, an ecological urban quarter for over 9,000 people is being created that will set new standards. Our goal is to consume as little energy as possible throughout the district, to generate as much renewable energy locally as possible and to cause as few emissions as possible. In this context, the SQUARE model project presents two interesting approaches to solutions."
Back in 2014, the model project for energy-efficient building refurbishment SQUARE (smart quarter and urban area reducing emissions) was awarded a prize in the "Klimaschutz mit System" (Climate Protection with a System) competition run by the Baden-Württemberg Ministry of the Environment. The SQUARE project application was prepared by the City of Mannheim's Economic Development Department in cooperation with the Climate Protection Control Centre. Thanks to the award, SQUARE was able to be included in the ERDF funding programme at the time and supported with three million euros. "SQUARE stands for one of the most ambitious projects in the field of GreenTech and climate protection in the city of Mannheim in the past decade. It is one of the pioneering projects developed from the "Blue City Mannheim" strategy concept of the Economic Development Department. The green tech innovation strategy from 2013 is still highly topical and sets the course for climate-neutral mobility and smart grids," emphasizes Mayor Michael Grötsch.
GBG - Mannheimer Wohnungsbaugesellschaft finally successfully implemented the model project on FRANKLIN. The first tenants moved in at the end of 2019. The two almost identical buildings were renovated according to different standards, one building according to the EnEV standard (SQUARE now), the second building with passive house elements according to an EnerPhIT standard (SQUARE next). Technologies such as smart grids, seasonal heat storage using ice storage and intelligent mobility concepts are being tested. The total of 48 rental apartments are spread across 3- to 5-room apartments between 84 and 109 sqm. "We are very excited about the insights we will gain through SQUARE. According to the calculations and simulations, we can achieve a CO2 saving of more than 50 percent in the comparison of the two buildings. In order to be able to save even more CO2, we are relying on the generation of regenerative energies. The ENEV building therefore received a photovoltaic system, the EnerPhIT building a solar thermal system," explains Karl-Heinz Frings, Managing Director of GBG.
"This is where the city of the future with the energy system of the future is being created," explains Bernhard Schumacher, head of the Smart Cities business unit at Mannheim-based energy company MVV. To this end, MVV is using smart technologies and the new possibilities of digitalisation on Franklin and is linking the various sectors intelligently and efficiently with each other - "not only to bring electricity, water, heat and mobility to the district, but also to make the new district the beacon of a necessary energy turnaround at the same time". MVV is also demonstrating what is already possible today in terms of electromobility on Franklin. In addition to environmentally friendly car-sharing solutions, such as FRANKLIN mobil, publicly accessible charging points are being set up, which will be networked with the energy management system and made more flexible. At the same time, the heating sector also plays an indispensable role. MVV has therefore built an innovative low-temperature heating grid here, which also enables the efficient integration of renewable energies.
Another item on the agenda of the visit is the three electric buses of the type E-Citaro, which have been in operation in Franklin on line 67 since April 2019. One of the buses was also funded under SQUARE. The environmentally friendly buses run every 20 minutes between the conversion areas on Franklin and the Käfertal Bahnhof stop. This will give people who already live, work or go to school in Franklin a direct connection to the rnv public transport network. "We are delighted to have EvoBus as a strong partner for this forward-looking project right on the spot," says Martin in der Beek, Technical Managing Director of rnv. "Over the past year, we have gained a lot of valuable knowledge in the operation of conventional electric buses and at the same time proved that the technology can stand up to the rigours of everyday public transport." In the future, however, other forms of propulsion will also be examined, he added. "We are currently looking intensively at the use of hydrogen buses in public transport and will soon be testing this technology at the rnv," reveals in der Beek. "Traveling by public transport is already more environmentally friendly per se than traveling by car, but we want to do even more for climate protection and therefore also convert our vehicle fleet to emission-free drives as far as possible."
