“Building owners and managers must remember that you can’t reduce what you don’t measure. Despite this, it can be difficult to understand where and how energy is used in these spaces – and quantify and lower carbon emissions.”
Yet despite this, around 85% of the 1.75 million commercial buildings in the UK are currently below a ‘B’ rating – meaning there are a lot of properties in danger of being left behind and becoming unlettable ‘stranded assets’ as a result. It’s therefore crucial that we find ways of
futureproofing the built environment against these regulations by reducing energy usage in these spaces.
HVAC monitoring can lower energy consumption
Monitoring HVAC equipment is one way to reduce energy usage in commercial buildings. These monitoring platforms work by collecting data on the energy consumed by HVAC equipment alongside other components such as temperature and humidity. In doing so, they continuously track and report on both the system’s energy consumption and performance within a building. This allows building owners and facilities managers to identify and analyse areas of high energy usage and take steps to actively reduce them – whether that’s by a simple tweak to optimse existing equipment or by installing energy-efficient alternatives. A growing number of monitoring platforms can
also record the energy consumption of third-party equipment, such as lighting, alongside HVAC equipment, allowing for a wider overview of energy usage in a building. Some solutions can then display this information on an energy dashboard, allowing building owners and operators to monitor and compare the energy consumption of multiple buildings by ranking their usage by kW per hour per building size or by the number of temperature or consumption alerts.
“Modern HVAC monitoring systems can identify systems with high energy output by tracking energy usage. This can then inform a plan for a change in room settings, a new, energy efficient schedule, a simple retrofit or an entire refurbishment, reducing energy usage and supporting a decarbonised future.”
At a more granular level, these platforms can
compare energy consumption between buildings, floors, rooms, individual units, and entire estates. Using this data, the platform can then help prevent
a single or multiple systems within a building from exceeding set temperature points and helping to reduce energy wastage; for example, a meeting room or shop floor where the heating or cooling has been left on overnight. Certain models can also limit units to cooling only in the summer and schedule these units to reduce or shut off operations during quieter periods or when no one is around. An increasing number of monitoring platforms also operate via the Internet of Things (IoT), meaning these systems can be operated and monitored remotely from mobile, PC or MAC devices. This means building owners and managers can manage system performance anywhere globally. As pressure builds to decarbonise the built
environment, we must support building owners and managers in adapting these spaces. Reducing the amount of energy consumed by HVAC systems via monitoring can help the UK in reaching Net Zero. Mitsubishi Electric recently launched the MELCloud Commercial HVAC controller. Find out more at https://
