BUILDING CONTROLS & TECHNOLOGY How IoT will guarantee building services uptime
IoT will enhance automation, enable efficient data collection, and ensure fast and effective analytics. It will optimise workflows, streamline processes, and most importantly, enable maintenance firms to predict and plan with precision. Fixing things before they break down, at the optimum moment, so everything runs continuously and seamlessly still comes with an air of futurism. But thanks to IoT, predictive maintenance is evolving at a rapid pace. Soon maintenance firms will be able to guarantee building services uptime.
The evolution of predictive maintenance
Planned preventive maintenance (PPM) is evolving. In the past, building maintenance operated largely by booking in services, changing filters and generally looking after the upkeep of appliances such as boilers, refrigerators, air-conditioning and ventilation. While much preventive work gets carried out in time, unplanned emergency repairs are still an essential component of this model.
Known as ‘time-based maintenance’, the servicing frequencies are based on warranties, supplier instructions, legislation or experience, for example, the annual servicing of an air-conditioning unit, or 6-monthly cleaning and/or changing of filters. But time-based maintenance can come too late, resulting in more extensive repairs than may have been necessary if a progressive problem had been picked up sooner.
Extensive real-time monitoring, data collection and analytics brings a wealth of extra information to the table. It means small issues can be
picked up sooner, common problems can be analysed, and preventive maintenance planned before wear and tear or breakdowns occur. IoT enables this to be done with far greater precision than has ever been done before. This, known as ‘condition-based monitoring’, is a far more efficient way of servicing, compared to arbitrary time-based maintenance. IoT means maintenance firms can be far more confident about guaranteeing building services uptime. And businesses needn’t be worried about how to incorporate IoT into their operational models - most equipment these days is already Smart or can easily be retrofitted with sensors to make them Smart.
Predictive maintenance will change in 4 key areas: ● Intelligence ● Real-time data ● Performance metrics ● Responsiveness and timely repairs
Intelligence
Artificial Intelligence (AI) will transform diagnostics by factoring in behaviour. For example - if a freezer in a restaurant or a supermarket is opened regularly at certain times of
