Revolutionising M&E Maintenance: Smarter Strategies For A Sustainable Future


Chris Coath, Director of Energy and Asset Management at NG Bailey, outlines a smarter, technology-driven approach to M&E maintenance that enhances efficiency, reduces costs, and supports sustainability targets.


The landscape of Mechanical & Electrical (M&E) asset maintenance has evolved dramatically. Gone are the days when simply toggling systems on and off was enough to save energy. Today’s buildings must balance multiple demands - air quality, uptime, and flexible workspaces - all while reducing energy consumption and meeting ambitious sustainability targets. With net zero on the horizon, facilities managers must rethink their approach.


Here’s the steps FMs should take when building and effective, future-ready M&E maintenance strategy.


1. Define your goals before diving into the data Before investing in analytics, sensors, and platforms, define what success looks like. Is the priority energy reduction, improved asset reliability, or alignment with net-zero commitments? Different buildings have different needs. For example, a data centre may prioritise uptime, while an office may focus on optimising energy use. By setting clear objectives upfront, facilities managers can ensure their maintenance strategy is aligned with their organisation’s broader goals.


2. Get the basics right first Before implementing digital maintenance, ensure fundamental practices are in place. One of the simplest and most effective steps is tracking energy consumption. Regularly reviewing energy usage - whether through a basic spreadsheet or an automated system - can highlight inefficiencies and reveal opportunities for cost savings. Engaging both the FM and maintenance teams in this process fosters alignment and accountability, ensuring that operational decisions support broader performance targets.


3. Build a strong foundation with a robust asset inventory A detailed asset inventory is essential for any maintenance strategy. Without an accurate record of equipment and its condition, optimising maintenance schedules and energy use is nearly impossible. Conducting an asset survey can provide the necessary insights to streamline operations and reduce costs. Once a clear inventory is established, integrating cloud-based energy

further enhance performance


4. Leverage technology for smarter maintenance Modern IoT sensors and smart building technologies are transforming M&E maintenance. Even in older buildings, real- time monitoring solutions can provide valuable insights without requiring costly infrastructure upgrades. For instance, occupancy and temperature sensors can improve HVAC efficiency, reducing energy


consumption while maintaining comfort levels. For


facilities equipped with a Building Management System (BMS), extracting and analysing existing data can further refine maintenance strategies and energy optimisation efforts.


5. Use data analytics for proactive maintenance With real-time data and advanced analytics, facilities managers can shift from reactive to proactive maintenance. Key benefits include:


• Continuous monitoring of building health • Dynamic maintenance scheduling to optimise performance • Predictive maintenance to prevent costly breakdowns • Improved energy efficiency and sustainability


By leveraging analytics, facilities teams can identify potential issues before they escalate, ensuring buildings operate at peak efficiency while minimising downtime and maintenance costs.


Bringing it all together


A strategic, data-driven approach to M&E maintenance transforms it from a routine operational task into a powerful enabler of efficiency and sustainability. By setting clear goals, leveraging technology, and utilising data-driven insights, facilities managers can optimise asset performance, reduce energy consumption, and contribute to their organisation’s net-zero ambitions.


While implementing digital maintenance solutions requires an initial investment, the long-term benefits, including improved efficiency, cost savings, and enhanced sustainability, far outweigh the costs. By taking a proactive approach, facilities managers can ensure their buildings remain resilient, adaptable, and ready for the future.
