Enterprise Ireland implemented ABB Cylon® Active Energy Manager across its 15,200 m² head office to reduce energy use. It identified a VRV air conditioning issue causing 24/7 operation and corrected it, resulting in a 14% electricity and 48% gas reduction with ROI in 12 months. The system enabled real-time monitoring, optimized HVAC with CO₂ sensors, improved sensor placement, and automated off-hours control. By 2015, energy use was down 36% (electricity) and 77% (gas) vs. 2010. It expanded to 8 offices with 91 data logs, ensuring ongoing savings and operational efficiency.
