Mission for the future of building affordable.sustainable.safe.

Fraunhofer-Institut für Bauphysik IBP Kommunikation
Fraunhofer-Gesellschaft

    Special exhibition by the Fraunhofer Building Innovation Alliance at the BAU 2025 trade fair in Munich
    Under the motto “Mission for the future of building-affordable.sustainable.safe”, from January 13 to 17, 2025, the Fraunhofer Building Innovation Alliance will be presenting innovations as part of its special exhibition at the BAU 2025 trade fair in three key areas of transformation in the construction industry: sustainability, productivity and resilience. The exhibits will be on display in and around a two-story Innovation Cube in Hall C2, Booth 528. The Innovation Cube is a symbolic building for demonstrating the latest smart solutions both for the building envelope and for the interior.

    The Fraunhofer Building Innovation Alliance sees its primary task as providing
    impetus for the urgently needed transformation in the construction sector. Its goal is
    to develop effective, future-oriented solutions for and with industry. It aims to identify
    prospects and formulate demands and tasks. To this end, the member institutes of
    the Alliance are conducting intensive research into new products and solutions. The
    focus is on criteria such as affordability, sustainability and resilience. “To some
    extent, climate change, social peace and the resilience of Germany's resources are
    decided in the construction industry,” says Thomas Kirmayr, Managing Director of
    the Fraunhofer Building Innovation Alliance, adding: “That's why we need to speed
    up this transformation and make it more effective and efficient. Research plays a
    crucial role here.”
    The exhibits from the Fraunhofer Institutes participating in BAU 2025 are grouped
    into three thematic islands “Sustainability”, “Productivity” and “Resilience”.
    They showcase new, innovative and effective materials, products and research
    results that can make the construction industry a “better” industry.

    A pioneering role in sustainability

    Sustainability is a key issue when it comes to the manufacture and use of building
    materials and to the operation of buildings. The production of concrete alone
    accounts for around 2.8 billion tons of CO2 emissions annually. One way of
    significantly reducing emissions is Carbon Capture and Utilization, or CCU for short.
    This involves the capture, transportation and subsequent use of carbon compounds.
    “With CO2-negative processes and building materials, with a carbon capture
    usability strategy promoted by politicians and with innovative ideas and research projects that go all the way to practical application in the construction industry, we
    could turn 2.8 billion tons of CO2 emissions into 4.6 billion tons of CO2 savings.
    Germany could secure a pioneering role in this field,” says Kirmayr. At the BAU
    2025 trade fair, exhibits will include new climate-friendly building materials that have
    these CO2 binding properties or new building materials which, through recycling and
    a well-thought-out circular economy, can be reused on construction sites.

    According to the German Federal Environment Agency, Germany's building-related
    final energy consumption has fallen in recent years, but still accounts for 35.5
    percent of the country's total final energy consumption. This is one reason to
    continue to push ahead with this development. The consistent expansion of
    renewable energies ensures energy generation and storage in buildings and
    contributes decisively to a sustainable heating transition. The concepts and products
    developed by various Fraunhofer institutes show how buildings can be operated in
    an energy-neutral way or even used to generate energy beyond their own needs.
    These include solutions in the field of photovoltaics and the use of renewable
    energies – for example, heat pumps instead of gas-fired heating systems, insulating
    materials made from renewable raw materials or with a smaller carbon footprint, and
    creative surface technologies for façades, windows and doors.

    Boosting productivity through sufficiency

    Building must become affordable again. This demand is growing louder and louder
    both in business and in politics. “What we need is knowledge transfer from other
    industries, such as the automotive or shipbuilding sectors, but also new system
    solutions that address the fragmented and small-scale structure of the construction
    industry,” explains Thomas Kirmayr. Another approach that could significantly cut
    building costs is an increase in digitalization and the use of artificial intelligence. A
    lead project of the Fraunhofer-Gesellschaft titled “BAU-DNS” is working on the
    development of key concepts for boosting productivity that aim to cut costs, increase
    circularity and achieve CO2 neutrality for materials and systems. Visitors to BAU
    2025 can see some of these solutions at the Innovation Cube, such as façade
    modules with integrated photovoltaics or digital methods for recording buildings
    quickly and accurately. In addition to boosting productivity, however, the focus must
    also be on sufficiency, which means making do with only what is necessary. This
    applies not only to the use of materials or resources, but also to bureaucracy and
    regulations, i.e. reducing them to a minimum.

    Resilience for safe housing and living

    Climate change and the growing scarcity of resources are challenges that are
    increasingly burdening our society. “Germany won’t be able to afford many more
    disasters like the flooding in the Ahr Valley,” says Thomas Kirmayr and calls for a
    resilience offensive: prompt answers are needed to the questions of how cities and
    buildings can be effectively protected against flooding, heat and extreme weather,
    how water management or a circular economy can be optimized, but also how the
    economy can be strengthened and how supply bottlenecks and constantly rising
    costs can be reduced. The Fraunhofer Building Innovation Alliance has specific
    measures in mind for this. For example, the consistent development and expansion
    of networks made up of universities, research institutions and industrial companies
    could help, as well as the establishment of a “Circular Economy and Urban Mining”
    research cluster as part of a federal construction research program, and
    interdisciplinary research consortia. At the BAU 2025 trade fair, concrete examples
    from research collaborations will be presented to interested parties. These include
    urban planning methods adapted to climate change, options for biodiverse façade
    greening, and the detection and removal of hazardous substances such as lindane
    or pentachlorophenol (PCP) that have been used in buildings.

    Lecture program

    In addition to the exciting and innovative exhibits, we invite visitors to attend
    informative lectures at our booth. Find out about the latest research findings and talk
    to our experts. The lecture program will be available for viewing on our website
    www.bau.fraunhofer.de in the coming weeks. Here you will also find further valuable
    and interesting information about the Fraunhofer Building Innovation Alliance's
    exhibition at the trade fair.
