Commitment and responsibility: the sustainable energy upgrading of the built environment

The 2030 framework for climate and energy policy, promoted by the European Commission (EC), highlights that the majority of energy-saving potential in the European Union (EU) lies within the building sector. Buildings account for approximately 40% of total energy consumption and 36% of CO2 emissions across the continent. Given these statistics, the role of European and national policies is crucial in establishing guidelines and pathways for action. However, in practical terms, the role of the designer is even more critical. Designers are directly responsible for leading the renewal process of a building stock that can no longer meet the new performance and quality standards demanded by the market. Across Europe, there are numerous examples of redevelopment, refunctionalization, and enhancement of the existing architectural heritage, showcasing a variety of strategies and intervention solutions. Drawing from specific case studies, this text will explore some of the most common strategies for intervening in the built environment.
