How can the sustainable transformation of the building sector succeed in Europe? This question was explored in depth during a high-profile panel at the Building Future Conference at ISH 2025 – with impressive examples, clear positions, and honest insights from practice.
A central topic: indoor air quality in schools and the crucial role of public awareness campaigns in fostering acceptance of mechanical ventilation. One thing became clear: window ventilation is no longer enough – we need modern solutions for healthy learning environments. The growing need for cooling due to climate change was also discussed.
The conversation ranged from European regulations and the implementation of the EPBD to real-world challenges in building services engineering and building renovation. It became evident that the greatest CO₂ savings potential lies in the existing building stock – but a lack of planning and investment security remains a key issue.
Subsidy models and tax incentives were also critically examined – how can owners, investors, and users be meaningfully motivated? Energy performance certificates were another hot topic: between standardized comparability and limited relevance to actual energy use.
Interested in the future of building, smart solutions for energy efficiency, and better indoor air quality? Then don't miss the recording of this insightful and practical discussion – full of ideas for planning, policy, and engineering!
