Towards energy efficient buildings by digital transformation of the building lifecycle

The global shift toward sustainability and the urgent need to reduce carbon emissions have placed the building sector at the forefront of climate action efforts. With buildings accounting for approximately 40% of global energy consumption (Jean-Pascal Tricoire, 2024 ) and a substantial share of greenhouse gas emissions (Ian Hamilton et al. 2024 ), this sector plays a critical role in determining whether we can meet international climate goals. As rapid urbanization continues to accelerate, the demand for energy-efficient buildings is becoming increasingly urgent (Renilde Becqué et al. 2024 ; Ma et al. 2021 )—not only from an environmental perspective but also from an economic and social standpoint.
