Energy use needs to be tracked and analyzed to identify inefficiencies and reveal opportunities to optimize operations.In addition, nearly 40% of CO₂ emissions come from buildings, primarily from operational energy use – e.g., HVAC, lighting – and, in turn, sustainability efforts are becoming a requirement in most large buildings. Facility managers need to track new metrics related to carbon savings and ‘green’ KPIs, including integrating on-site renewable energy resources. BMS modernisation is one way to ensure your efforts will help reduce energy consumption across all operational systems.
