“For a climate-neutral building stock, the existing data silos must finally be broken up!”

The Federal Institute for Research on Building, Urban Affairs and Spatial Development (BBSR) is the departmental research institute of the Federal Ministry of Housing, Urban Development and Building (BMWSB). We talk to Thomas Tschirner, a member of the “Climate neutrality in building operations” unit in the Housing and Construction Department, about the opportunities and possibilities of a climate-neutral building stock in Germany and the motivation for participating in SmartLivingNEXT.

Germany aims to become climate-neutral by 2045. In your view, what significance does the digitalization of existing buildings have in this context?
Our core problem is that knowledge of the building stock in Germany is still very patchy. In our view, the availability of energy-relevant data should be at the heart of future efforts. Digitalization and the resulting availability of data is a decisive factor in closing precisely these knowledge gaps in order to place measures and incentives for phasing out fossil fuels in the building sector in a targeted manner.
In your opinion, what role could the SmartLivingNEXT data room play in achieving the climate targets?
For us, the crucial thing about the common data room is that the existing data silos are finally being broken down. These make broad data availability difficult. With the SmartLivingNEXT Dataspace, data can be made available for a wide range of energy-related applications and evaluated more easily. And without the data providers losing control. Especially in the area of municipal heating planning, this valid data is urgently needed as a planning basis, for example for the expansion of district heating networks.
What potential does the use of artificial intelligence (AI) have?
AI processes are very promising. However, they can only work if there is sufficient data availability. So if we want to create a good and valid database for AI processes, the shared data space is a perfect instrument for this. I also don’t think that this path can be shortened. There is a great need for data for training, and the SmartLivingNEXT data room can play a central role in meeting this need.
Which smart services do you consider to be particularly interesting here in order to generate added value for you? Please also think about services that do not yet exist in this form, but which could in principle be created through a shared data room.
I myself am very excited about further developments in this area. I can imagine that applications for dynamic load shifting will play an important role. At the moment, however, my focus is still very much on how successful it will be to establish a generally recognized data space with valid data and transfer it to regular operation.
What results or synergy effects do you hope to achieve as an associated partner through the technology program?
It is very exciting and instructive for us to follow the development of the data room, with all its challenges and successes, so closely. We hope to be able to transfer many findings and methods to a future data room for residential and later also for non-residential buildings – the research area of our department.
