Wireless monitoring system extends LED energy savings

The system can be used to benchmark consumption patterns and influencing environmental factors ahead of a lighting refurbishment programme. It is equally suited to long-term applications where it can be used to identify ongoing energy efficiency opportunities in a room, building or across an entire estate.

The system works by collecting data via RF from a range of metres and battery operated wireless sensors attached to specific circuits. The system reports to one or more GPRS gateways with a range of up to 15km line of sight.

These operate on a frequency that will not interfere with existing equipment or IT infrastructure. In most instances, the sensors are simply clipped into place and require no additional wiring. Where this is not possible a split-core voltage current transformer is used. In 90% of applications, existing equipment can remain in operation during the installation period.

Most units of this type collect data over a 24 hour period, aggregating it to provide consumption information. The Minimise Monitoring and Control system provides reported data constantly, giving users a much clearer picture of their energy use and the factors that impact consumption.

It can also be used to assess a business’ wider energy consumption patterns. By monitoring continuously, the system can determine previously ‘unseen’ activities that directly affect energy waste – such as the impact of door and window openings on a building’s heating bills. 

This continuous monitoring is also ideal for unmanned buildings where a change in the reported environment can be used to trigger an email alert to an individual who can take the appropriate action.

The resulting information can be used by facilities or energy managers to identify opportunities for improvement. It can also be used by Minimise’s energy efficiency specialists to devise a bespoke LED solution for each business’ individual energy profile.

For many commercial applications, data of this type can accurately calculate energy savings, and so is fundamental in unlocking infrastructure improvement budgets at board level.

“The Minimise Monitoring and Control System gives businesses the opportunity to gain a firm understanding of their existing energy usage and the precise savings available, ensuring the correct light levels are achieved with the minimum energy,” said Nigel Dawson, Monitoring and Controls Product Director at Minimise Energy.

“In terms of LED lighting, the system can be used to monitor existing fluorescent outputs and the like-for-like savings LEDs can bring. Further available savings, achieved by fitting motion sensors, for example, can also be accurately projected through the software.”
