The Herta Mohr building at Leiden University exemplifies sustainable innovation as its first fully gas-free structure, expected to reduce carbon emissions by 150,000 kg annually through a new thermal energy storage system. It has achieved an ‘Excellent’ BREEAM rating. 

The renovation focuses on reducing ecological footprints across various aspects, including energy, waste, and nature conservation, with features like bat roosts. Retaining unique ‘mushroom columns’ posed challenges, yet the design balances aesthetics with sustainability.

The surrounding space has been redesigned for climate adaptability and biodiversity, enhancing community well-being.
