Initiated in 2022 by the Federation of European Heating, Ventilation and Air Conditioning Associations (REHVA), the Healthy Buildings Design Competition (HBDC) is a university-level student competition for healthy, comfortable, energy-efficient, and resource-responsible architecture and engineering in the building sector.

In the 2025 edition the focus was in on primary schools, particularly on the renovation of primary schools built during the baby boom of the 1960-1970s across Europe. While some have undergone renovations, many still lack the care and attention needed. It's time to reimagine and redesign these educational spaces to meet the evolving needs of users, create comfortable and sustainable environments, and ensure resilience in the face of future challenges.

The challenge posed to teams participating in the HBDC25 was to design the renovation of a primary educational building skilfully in a cost-effective manner. The goal was to achieve an appealing result that prioritizes enhanced health and energy efficiency.
