Europe’s shift towards greener, more energy‐efficient futures is spurring a construction revolution. In Germany, nearly two‐thirds of activity focuses on retrofitting and sustainable upgrades rather than new builds. This trend, underpinned by efficiency and market demands, offers a clear template for transformation. The study by Heinze Marktforschung highlights significant benefits from modernising ageing structures across Europe with impressive cost savings.

Portugal faces an imperative to modernise its ageing building stock, with significant energy inefficiencies and remarkable untapped economic opportunities. Expert panels at the Portuguese Real Estate Show agree that retrofitting is both an environmental and financial necessity. Embracing sustainable modernisation can reduce waste, lower emissions, and stimulate robust investment, ensuring a competitive property market and enhanced long‐term resilience with impact.
