Unanimously, on March 21, 2019, members of Berlin's state parliament voted in favor of promoting urban timber construction.
Following in the footsteps of Baden-Württemberg, the state of Berlin has now also decided to focus on wooden buildings in the future with its application "Sustainability in construction: Berlin builds with wood". As part of the Berlin Energy and Climate Protection Programme (BEK), wood as a building material is to be used to a much greater extent from now on and, as a carbon dioxide reservoir, is to make a contribution to climate protection and resource efficiency.
As the largest builder in the city-state, the Berlin Senate is to lead the way in the future and increasingly use wood in state buildings such as schools, kindergartens and residential buildings. In addition, subsidy programs such as those in Baden-Württemberg, Hamburg and Munich should create incentives for private builders. A timber construction cluster is to develop and bundle competencies along the value chain in the long term.
Since April 2018, an amendment to Berlin's state building code has facilitated timber construction for private and public buildings. Load-bearing components of multi-storey buildings can now be made of the natural material without the need for a time-consuming case-by-case assessment.
For new buildings and complete modernisation projects, Berlin will in future apply the Sustainable Building Rating System (NBB) with its defined, transparent standards for sustainability.

In the Bavarian 10,000 Houses Program, there is now also money for electricity storage units if the user installs them together with a PV system. Until the end of 2020, 24 million euros are available for the entire program.
The Bavarian Ministry of Economic Affairs has launched the new photovoltaic storage programme. It is part of the well-known 10,000 Homes Programme. From 1 August, owners of detached and semi-detached houses can apply for funding for a new electricity storage unit in conjunction with a photovoltaic system. In addition, there is the possibility for a grant for the installation of a private charging station for electric vehicles.
"We need to make better use of the sun's potential," says Minister of Economics Hubert Aiwanger. " With the new support programme, we will give additional momentum to the energy transition. It sets the right incentives to advance the decentralised expansion of renewable energies in Bavaria and will actively involve citizens in the energy transition." Citizens can also reduce their electricity costs with the help of the programme. The smart controls and connections provided for under the funding will also enable plant operators to participate in regional direct electricity marketing in the future.
The subsidy amount is graduated according to the capacity of the battery storage unit and ranges from 500 euros for a three-kilowatt-hour storage unit to 3,200 euros for a 30-kilowatt-hour storage unit. The prerequisite, however, is that the applicant simultaneously installs a new photovoltaic system whose output in kilowatt-peak is at least equal to the value of the capacity of the battery storage unit. For an additional charging station for electric vehicles, the subsidy is 200 euros. The Ministry of Economics is providing up to 24 million euros for the 10,000 Houses Programme until the end of 2020.
The successful EnergySystemHouse programme component will be continued. There, too, the use of solar energy and its storage in combination with energy-efficient refurbishment or particularly efficient houses and systems will be promoted. "The targeted promotion of innovative technologies is working, manufacturers are developing new systems and bringing them to market," says Aiwanger. "The number of particularly efficient heat pumps on the market has increased from 40 models to over 160 models. In the case of high-efficiency heat storage systems, the eligible models have increased fivefold to more than 250 models in the same period. Energy advisors report that many building owners are improving their plans and constructing or refurbishing buildings much more efficiently because of the programme."
All subsidies of the 10,000 Houses Programme are coordinated with the federal programmes and can be combined. It is very easy to apply electronically. Further information and the application platform can be found under this link.

► Consistently tap alternative heat sources such as wastewater heat
► Convert public buildings to renewable heat and form district heating networks
Ambitious energy-efficient refurbishment, even in areas protected by the Milieu, so that warm rents remain affordable
BMBF project "Urban Heat Turnaround" by the Institute for Ecological Economy Research, law firm Becker Büttner Held and Berliner Wasserbetriebe presents recommendations
The advancing climate crisis, the war in Ukraine, the associated uncertainties and price increases - there are many reasons to get out of oil and natural gas as quickly as possible when it comes to heating. In order for the heat transition in cities to progress faster and more effectively, energy experts of the project "Urban Heat Transition" recommend a mix of measures: cities should develop a spatial heat planning and tap all sustainable heat potentials such as wastewater heat. In addition, they should expand district heating, create neighbourhood heating networks - especially around public buildings - and support fair energy refurbishments in protected areas. Funded by the Federal Ministry of Education and Research (BMBF), the Institute for Ecological Economy Research (IÖW) developed recommendations for states, cities, municipalities and neighbourhood managers together with the law firm Becker Büttner Held (BBH) and the Berliner Wasserbetriebe as well as representatives of the Berlin Senate and district administration.
Using Berlin as an example, the research project investigated central aspects of a climate-neutral heat supply. So far, the capital still depends on natural gas for two-thirds of its heating, heating oil for 17 per cent and coal for five per cent. "Berlin is facing challenges in the heat transition that other cities are also familiar with: Rising rents fuel fears of expensive renovation projects, the change has not yet reached the neighbourhoods despite funding pots and technologies such as the use of wastewater heat are only slowly being implemented," explains project manager Dr Elisa Dunkelberg from the IÖW. "In two and a half years of practice-oriented research, we have compiled solution strategies that should not be missing from any urban heat planning."
Higher thermal insulation standards also in areas protected by urban development law
The next heating bill will show tenants how expensive it is to depend on fossil fuels. Even if the markets calm down, the CO2 price will rise. That's why energy-efficient renovation that goes beyond the legal minimum standards can also be worthwhile from the tenants' point of view: If landlords use subsidies and allocate the modernisation costs fairly, the warm rent remains stable or can even decrease, as the researchers have calculated.
Especially in areas of social preservation, municipalities should allow more ambitious refurbishments: "In Berlin's 70 or so social preservation areas, ambitious energy refurbishments have rarely been approved so far. The same applies to a change from gas floor heating to renewable energies or district heating," says Charlotta Maiworm from BBH. "In order to keep rents affordable in the long term, these projects should be approved - but only under certain conditions or stipulations, such as that the costs for tenants may not be higher than the measures according to the regulatory minimum standard." The research team summarises in a guideline what municipalities and neighbourhood managers should pay attention to.
Alternative heat sources: Wastewater heat & Co.
In order to use resources efficiently and minimise energy imports, local heat sources must be used extensively. While some cities have great potential in individual areas, such as Munich with geothermal energy and Hamburg with industrial waste heat, other cities such as Berlin must exploit all potential and aim for a broad mix of environmental heat pumps, commercial waste heat, direct electricity use and biomass.
One heat source that is available all year round in all cities and only needs to be "tapped" is wastewater heat: it could be an important building block in the future energy mix and, for example, cover up to five per cent of the heat demand in Berlin in the future. "For their municipal heat planning, cities need information about where and to what extent wastewater heat is available and how it could be used," says Michel Gunkel from Berliner Wasserbetriebe. "In the 'Urban Heat Turnaround' project, we have therefore prepared this data in a geo-based tool - the wastewater heat atlas - which we are currently testing in an internal test phase."
Heat planning and district heating networks
The information from the wastewater heat atlas must be merged with other data, such as heat demand, for heat planning. The goal of heat planning is to find out where climate neutrality can best and most cost-efficiently be achieved with which future heat supply. District heating makes sense where renewable heat and waste heat potentials exceed the demand of individual buildings. "To shoot for local heat sources, public buildings play a central role," Elisa Dunkelberg emphasises. "If a large wastewater heat pump is installed there, for example, it can also supply surrounding houses via a neighbourhood heat network." Whenever public buildings are due for heating changes or renovations, it should therefore be checked whether a district heating system is possible. Sample calculations show that with the planned federal subsidy for efficient heating networks, neighbourhood heating can be offered at competitive prices. The researchers also propose measures to facilitate implementation - such as model contracts and criteria catalogues.
At the conference "Urban heat transition - How cities can supply themselves with climate-neutral heat" at the end of March, more than 300 administrative staff and neighbourhood managers from various cities learned about the current state of research on the urban heat transition.
