The cleverly simple ‘mini’ BEMS from Prefect

Sponsored: Energy saving, energy management, energy flexibility

Many large buildings utilise Business Energy Management Systems (BEMS) and they certainly have their place. However, as advised by The Energy Institute, one of the principles in deciding on which BEMS is the most effective for a particular building, is to choose the simplest system that meets the requirements of the building.

It’s better to have a system that can grow with the building’s needs, rather than having an over-complex system, that is difficult to use, with lots of its functionality ‘turned off’.

So, while complex BEMS have their place in our commercial and industrial world, in some cases a simpler solution, if considered early on, can be more effective in terms of functionality and price.

PrefectIrus – simply put – is a system that is capable of providing integrated control and monitoring of heating, lighting, ventilation and other key functions from any convenient central location.

PrefectIrus might be classified as a ‘mini’ BEMS in as much as the functions under control represent the vital building services. However, it offers the benefit of being very easy to use and, because of its mains-borne signalling operation, is easy to install and therefore more cost effective than its bigger brothers.

Furthermore it enables management to set and monitor comfort and ‘sleep’ temperatures whilst controlling time profiles in each bedroom separately. This level of localised control over individual rooms is not possible with other building management systems despite their other capabilities.

‘Because PrefectIrus is a software-driven package, it has the ability to provide bespoke features.’

For student accommodation the system allows the onsite management team to tailor the time temperature profile to achieve the maximum energy saving possible, whilst providing a comfortable living environment.

The PrefectIrus interface unit is connected to the building power supply and a broadband internet connection. The systems software then allows secure access from anywhere, in the event of a failure at any point – essential building services are able to continue operating locally under manual control.

But savings don’t end with reduction of energy use, choosing when to use energy can provide even greater savings!

In partnership with Open Energi, Prefect Controls has rolled-out its DSR technology across Prefect Controls’ network of university partners to deliver 8MW of flexibility to the UK grid.

Demand Side Response has been identified as a key solution for future-proofing the UK’s electricity grid, and National Grid has launched Power Responsive to help deliver Demand Response at scale by 2020.

Glen Golding, CEO, Prefect Controls said “As a specialist in energy management, we recognise the value of Open Energi’s Dynamic Demand technology in delivering even greater efficiencies for our university partners. It will allow us to work with customers across our business to make their buildings and devices even smarter, helping them to better manage their energy needs and provide the opportunity to reduce carbon emissions while generating new revenues.”

Additionally a diagnostic programme is included to highlight fault finding and speed up maintenance. Two-way communication is standard with PrefectIrus, so status reports for temperature or boost conditions in any room are available through the password-protected ‘engineer program’, The PrefectIrus engineering status screen allows quick diagnostic of heating, lighting or even cooling for each location.

Because PrefectIrus is a software-driven package, it has the ability to provide bespoke features, which have recently been developed to incorporate not only temperature sensing but also humidity and lux sensing and decibel awareness. Each installation can be set up to meet the unique requirements of the client.
