work. Increasingly companies are turning to condition based maintenance (CBM), based on the actual operational and performance context, rather than ‘what the manual says’. As maintenance techniques become increasingly sophisticated, the opportunity is presented for a more positive and proactive approach to maintenance, presenting this as a profit centre, rather than an expense. Through an approach, based on the actual condition of equipment rather than a predetermined schedule. Assets can be maintained at a continuously high level of performance, instead of waiting for something to fail. Repairs and maintenance can be prioritised so that the most important systems are repaired first.
Reactive maintenance is the most costly way to maintain building HVAC systems. Organisations that have introduced planned and predictive maintenance programmes have seen dramatic decreases in maintenance costs. When extended equipment life, reduced energy use, less frequent system downtime, and decreased interruptions to building operations are factored in, costs can be as much as 50% lower.
At Société Générale in Tower Hill, London, where the bank’s critical datacentres are housed, the company introduced Asset Insight

Manager (AIM) on their most critical assets. The vibration, temperature, acoustics and power of the assets is monitored in real time and readings are translated by the AIM asset performance system to establish event detection and alert the engineers to any pending failure. This enables them to respond in a controlled and planned manner. Through a shift log module, which interacts with the asset and works management modules, the quality of the energy consumption data was enhanced so that the bank could sharpen its focus on energy reduction. Specifically, where the plant and equipment do not have an intelligent meter or monitoring device to transmit data automatically, the engineering team can now input consumption data via a handheld device during plant tours and inspections, updating the information live to the system’s dashboard.
Condition-based maintenance, assisted by developments in machine to machine (M2M) technology, smart assets and real time links to equipment, enables assets to be maintained based on their actual operational context and performance through a flexible, data-driven model. Smart technology and the Internet of Things (IoT) are also transforming the asset management model. Wi-fi has removed the human-factor
and has given assets the power to talk to each other, resulting in the joined-up capturing and sharing of information. More and more Building Management Systems (BMS) and HVAC systems will have an intuitive interface that allows a wide range of monitoring, reporting and diagnostic tools across multiple sites in a single integrated system. Ubiquitous connectivity allows FMs to visualise and manage data, creating detailed analyses and predictions for CBM and a maintenance model that can be modified for individual assets.
“ORGANISATIONS ARE LIKELY TO FACE
INCREASED ENERGY COSTS OF AROUND
ONE THIRD THROUGH TO 2030.”
Driven by rising electricity costs, green legislation, and business sustainability, the cyclical approach to maintaining assets and traditional intrusive repair methods of are becoming increasingly less relevant for meeting the business challenges of the future.
