ABB Cylon® Active Energy Manager helped a commercial office building cut electricity use by 14% and gas by 48% over four years. Integration with the BEMS revealed inefficiencies like unnecessary VRV system use, which were corrected, saving up to €100,000 annually. Measures included sensor optimization, equipment scheduling, and CO₂-based AHU control. Additional low-cost improvements led to €75,000 in savings. The system enabled smart monitoring, ROI tracking, and tenant comfort without extra capital costs, while also extending equipment life and preventing up to 20% annual energy drift.
