European builders and owners tend to be more concerned about smart buildings due to stricter regulations on energy efficiency and sustainability, which are increasingly prioritized by governments and the European Union. Additionally, European cities are often more compact and urbanized, leading to a greater emphasis on integrating technology for improved building management and reduced environmental impact. The cultural focus on sustainability and innovation also drives greater investment in smart building technologies in Europe compared to the U.S.
