Honeywell is preserving Europe’s cultural heritage while advancing smart, sustainable building solutions. At Budapest’s Buda Castle, Honeywell modernised the information technology infrastructure with integrated systems for security, communications and energy management, protecting priceless artefacts while streamlining operations. Likewise, at Amsterdam’s Johan Cruijff Arena, Honeywell deployed Internet of Things-enabled technology and machine learning to optimise energy use, enhance fan experience and cut costs. Together, these projects showcase how Europe’s most iconic landmarks can embrace innovation while reducing environmental impact. Learn more on Invested in Europe.
