The objective of this report is to provide an overview of the interlinkages between the renovation of school buildings and the climate and energy targets adopted for public buildings in Berlin. The report uses an analysis grid to systematically identify these interlinkages. The report focuses on the Berlin School Construction Offensive, “Berliner Schulbauoffensive” (BSO), which is a concerted effort among several administrations, districts and specialised agencies to coordinate and accelerate the renovation and construction of school buildings.

By applying an analysis grid, the report...

Berlin has set itself ambitious climate targets. In this context, social aspects of the heat transition in Berlin have become an increasingly important issue in view of the scarcity of housing, rising rents and very different housing costs for households. Particularly low-income households suffer from high housing costs. Often, they already take up a large portion of their income. An increase in rental costs or energy costs carries the danger that households can no longer afford their housing or pay their heating and electricity costs. In order to make climate protection socially acceptable...

Alternative economies are an essential part of Berlin's socioeconomic landscape and integral to the social and ecological transformation of the metropolis. Yet, there has been a widespread lack of understanding of businesses that operate differently in terms of their social mission, alternative organization and specific needs.

This final report of the project “Alternative Economies in and for Berlin” should be understood as a first step to change this. For this purpose, the project team talked to experts from practice, politics and administration over the period of one and a half years...

As part of the project “Circular City Berlin - Pathways from Potential to Implementation”, a transformation roadmap for circular textiles was developed. It displays how the idea of Circular City Berlin can be advanced in the area of textiles. The goal of a greenhouse gas-neutral and resource-productive Circular Economy requires a significantly higher level of ambition in Berlin, Germany and the EU compared to current efforts. To achieve this, the following measures need to be pursued: First, model projects for circular textiles should be initiated, e.g. projects that address a better...

Innovation towards circular construction in Berlin is characterised by a variety of different actors who are pursuing projects, business models and practices that can be used to strengthen the circular economy, resource conservation and cli-mate protection along the life cycle of building projects. The spectrum ranges from modular building designs to the re-use of entire buildings or building components to the high-quality recycling of building materials for further use. At the same time, several barriers hamper the diffusion of circular construction approaches, e.g., lacking demand for...

In order to achieve climate policy goals in the building sector, not only a transition of heating systems to renewable energies but also comprehensive energy refurbishments to reduce the heating demand are necessary. This involves a high investment requirement, which must initially be covered by the landlords. Tenants face challenges due to the resulting rent increases as a consequence of the modernisation allocation.

Due to the already tense situation on the Berlin housing market, the question arises as to whether and under what conditions energy-efficient refurbishments can be carried out...

This study is part of the project "Circular City Berlin - Pathways from Potential to Implementation", which investigates the potential of a circular economy in Berlin and its social and environmental impacts in three sectors: textiles, construction, and information and communication technology (ICT). The project explores possible pathways to implementation, and supports a diffusion of possible business models. 

In addition to the amounts of waste avoided, the calculations show the potential of the circular economy to help address the climate crisis by reducing the overall material: with the...

Prinzipien der Datennutzung für ein sozial-ökologisches Berlin: Leitideen einer nachhaltigkeitsorientierten Datengovernance

Wissen. Wandel. Berlin. Report 4

Data-driven innovations have enormous potential to make the existing economic and social order more just and environmentally sustainable. However, the past two decades have shown that such potential by no means materializes automatically. Rather, public interest-oriented management of data use is a complex political task that must take various interests and goals into account. This challenge also and particularly arises in a modern metropolis like Berlin. The formulation of principles for a social-ecological use of data can provide orientation and sharpen the view for conflicts of goals and...

The innovation field of construction is a resource-relevant field in Berlin – in 2017, the construction sector accounted for about 22 percent of the raw material input of the state of Berlin. Currently, the recycling rate for mineral construction waste is around 50 percent, and is expected to increase to more than 60 percent by 2030. Circular economy approaches in the field of construction have to cover the entire life cycle: from the design of durable and deconstructable structures to the use phase and material-preserving re-use to circular business models.

Against this background, this...

Berlin tenant electricity systems have positive ecological and socio-economic effects, but these remain relatively low compared to the technically available potential. At the end of 2020, 74 PV tenant electricity projects with a capacity of 12.6 MWp were in operation in Berlin, the CO2 savings amount to around 4,100 t CO2 per year. This means that less than 1% of the potential is used. The survey carried out in the project shows that tenant electricity is rated positively. Especially for households with low incomes, the low price is the most important reason for tenant electricity. Scheme...
