Building management systems (BMS)

Central to effective facility management, BMS provides operational intelligence that enables energy efficiency, reduces emissions, and improves building performance. However, many BMS installations are underutilised or poorly maintained.

Data-driven approach to sustainability

Collecting, analysing, and acting on data is essential for identifying energy wastage and targeting improvements. This aligns with the maturity framework used by sustainability consultants, progressing from baseline assessments to smart target setting and ongoing improvement cycles.

Energy efficiency as core to Net Zero

Net Zero cannot be achieved by offsetting emissions alone; organisations must reduce energy consumption, focusing on identifying wastage through monitoring and control systems.

Engagement and next steps

• Conduct a BMS audit to assess system condition, installation date, maintenance, and operational settings.
• Identify quick wins such as adjusting schedules, linking heating to occupancy, and reducing base loads.
• Start small with pilot projects and scale savings.
• Ensure technology choices are open protocol and interoperable.
• Use clear, meaningful data visualisation tailored to user needs.
• Engage with experts to develop realistic Net Zero roadmaps aligned with organisational drivers.

Challenges in building management

• Outdated or fragmented BMS systems.
• Lack of real-time, actionable data.
• High initial costs and unclear ROI.
• Limited staff expertise and budget constraints.
• Resistance to change among building occupants and unions.

Practical solutions and quick wins

• Start with baseline monitoring before implementing new technology.
• Use occupancy data to optimise heating, ventilation, and lighting.
• Implement room-level controls for granular management.
• Avoid technology for its own sake; focus on fixing management processes first.
• Use open protocol systems to avoid vendor lock-in and enable future scalability.
