The Conference

sbe22 berlin as an entry point to global discussions on a local level 

The sbe22 berlin will be hosted by the Institute of Architecture of TU Berlin which will provide a design-oriented, architectural and urban planning entry point to a broad, inter- and transdisciplinary debate on the following themes:

• resource management and material flows
• climate neutral buildings
• post-fossil infrastructures
• critical digitalisation and
• socio-political frames for transitions.

These themes represent key solution areas to address sustainability challenges within the planning and building sectors. The conference „Built Environment within Planetary Boundaries“ is to bring together and network the diverse communities of researchers, practitioners and decision makers to critically discuss cutting edge research as well as innovative policies and practice based on the planetary boundaries model. The conference will address different scales, disciplines and approaches ranging from material and product development, building design, structural engineering, urban and regional planning to innovative manufacturing processes and the design of circular value chains.

The sbe22 berlin D-A-CH conference is a collaborative project together with KIT Karsruhe, TU Graz and ETH Zürich.





Resource Management and Material Flows

Rethinking circular principles indesign and construction processes

Read more

Responsible and intelligent management of resources used in the planning and construction sector is of increasing importance for climate-smart planning of the built environment. Planetary boundaries can be understood as a guide to ecological stress limits that are directly related to the occurrence and management of natural resources. For the necessary decarbonisation of the construction sector, sustainable resource management as well as material flows and logistics must be considered as a necessary overriding principle in the climate-just planning and construction process. This implies increased use of circular and naturally renewable raw materials with simultaneous transformation of resource management and certification systems, intelligent manufacturing processes that can save resources, and strategies for selective deconstruction and reuse of building materials.

Climate Neutral Buildings

Net-zero emission targets andmitigation strategies

Read more

The goal of reducing the immensely high direct and indirect CO2 emissions of the building sector can only be achieved by taking an integrative view of energy consumption and energy generation over the entire life cycle of a building or district. The field of climate-responsive energy systems includes the evaluation of embodied energy, therefore the sustainable transformation of existing building stock as well as low-tech design and construction principles and the targeted integration of renewable energies in planning and construction processes.

Post-Fossil Infrastructures

Natural systems and biodiversity inurban planning and design

Read more

For an ecologically valuable built environment that creates space for humans, animals and plants rather than it takes up and consumes space and resources, our physical infrastructures such as water systems, designed and natural green spaces as well as mobility and transport infrastructures need to be prioritised in sustainable planning and building processes. New and existing infrastructures must be designed, transformed and adapted to climate-friendly buildings, cities and settlements or even define the boundaries of planning.

Critical Digitalisation

Big Data in design and planning and planning

Read more

This solution field is about discussing and reviewing technologies and measures of digitalisation for their benefits in sustainable planning and building. A built environment adapted to the planetary boundaries does not necessarily require more technologies, but the effective or efficient use of only certain technologies to achieve climate action goals. The critical factor in the discussion about digitalisation in the building sector includes the costly consumption of resources for the production of digital tools, as well as the energy consumption for data storage, which is the basis of many technological solutions.

Socio-Political Frames for Transitions

Governance models and actor networks

Read more

This Solutions Field aims at the organisational and action structures in the planning sector as well as their necessary development, reorganisation and adaptation to enable a climate-just development in the planning and building sector. This includes development-oriented and actor-driven approaches in planning, urban policy and urban management. Which models or practices are convincing with experimental, innovative or novel approaches at the interface of science, economy, politics, administration and civil society?

Open Call for New Topics

Rethinking circular principles indesign and construction processes

Read more

The Open Call for new topics addresses scientists that are researching in fields of sustainability and the built environment without matching one of the above topics. Here new topics as well as interdisciplinary approaches and other fields of expertise are welcome to broaden the horizon and integrate new questions in current scientific discourses.



The metropolitan area Berlin-Brandenburg as an incubator of transformation

With over 3.5 million inhabitants, Berlin is not only the capital of the Federal Republic of Germany, but also an international metropolis that attracts people from all over the world with its promise of culture, creativity and innovation. One hundred years after the founding of Greater Berlin in 1920, Berlin and the state of Brandenburg are facing similar challenges today as they did at the beginning of the 20th century; namely rapid population growth resulting in housing shortages and rising pressure on increasingly outdated infrastructure. Berlin’s economy is nevertheless thriving and diversifying rapidly as a result of advancing digitalisation and the necessary energy transition.

Berlin’s special role in the political and cultural history of 20thcentury Europe meant that until about 10 years ago, the city wasendowed with a incomparably high number of centrally located butundeveloped or derelict urban spaces. This allowed architects,planners and activists the freedom to realise many of theprogressive urban projects for which Berlin is known today. Thisdynamism allows Berlin to continually push boundaries throughexemplary projects in architecture, urban and regional planning, aswell as with innovative partnerships from politics, science, businessand civil society. Some of the current projects with internationalappeal include the Schuhmacher Quartier at the former Berlin-Tegel Airport with a focus on sustainable urban development andthe Haus der Statistik block, which is setting new standards for anew type of bottom up and commons orientated urbandevelopment.In 2006 the two state governments of Berlin and Brandenburgcommitted themselves to a joint mission statement regarding thedevelopment of the Berlin-Brandenburg metropolitan region. Thenecessary transformation of the city and surrounding region can beunderstood as a resource/transformation region , allowing theformation of synergies between these two very different contexts.In the context of integrated and sustainable planning, places oftransformation such as the brown coal region of Lausitz, have thechance to become future model regions. In this sense the Berlin-Brandenburg metropolitan region has the potential to become aliving laboratory for innovative regional, urban and ruraltransformation processes.This potential makes Berlin-Brandenburg the ideal venue for thetransdisciplinary SBE conference. These cutting-edgetransformation projects will be actively integrated into theconference programme, contributing myriad themes, expertise andnetwork potential to the exchange.


TU Berlin and Natural Building Lab

A transdisciplinary network generating knowledge and built prototypes for a post-fossil society

We believe that resource scarcity and climate change require us to rethink the way that we live, work and consume on all scales. 

This transformation has serious consequences for designers and the built environment. Climate- and resource-adapted, circular building systems using renewable or reused resources and healthy low-tech building with climate-active natural building materials can enable a future-oriented building culture, that can exist and thrive within the planetary boundaries model. At the interface between academic and non-academic environments, we develop applied solutions in research, teaching and practice, that follow holistic principles and are oriented towards the common good. We are convinced that a post-fossil built environment will emerge from transdisciplinary processes that will involve the next generation of architects working with other specialist disciplines, industry, craft and society.

Natural Building Lab was founded in autumn 2017 at the Institute of Architecture, Faculty of Planning, Building, Environment at the Technische Universität Berlin as a specialist area for constructive design and climate-friendly architecture.
