Siemens AG has published the Infrastructure Transition Monitor 2025, revealing that improving energy efficiency in buildings has become the top infrastructure priority for organizations, a significant rise from seventh place in 2023. The study, which surveyed 1,400 senior executives and government representatives across 19 countries, found that 55% of organizations plan to increase investment in smart building technologies, and more than half are ready to implement autonomous building systems. Despite strong returns on investment from retrofits, cost-related barriers such as lack of capital and rising energy prices are slowing the transition to net-zero buildings. Siemens is addressing these challenges by offering Energy-as-a-Service models, allowing organizations to replace large upfront capital expenditures with outcome-based operational costs. Digitalization is also seen as transformative, with over half of respondents expecting it to reduce costs and improve workforce health and safety.
