Leocycle Smart Facilities Management

Using smart technology to identify a lethal biohazard

Cubik Innovation has a history of engineering electronic systems which deliver key improvements in public health and safety whilst limiting the environmental impact. We were delighted to be able to partner with local smart facilities management start-up, Leocycle, to create a device that could detect the risk of Legionella and Legionnaires’ disease in hospitals, hotels, offices, and other public buildings.

Legionella are transmitted to a host via stagnant water droplets in the air which can occur, for example, from a tap that has not been used for a period. The only way to remove the threat is to perform manual flushing of every potential risk area. In some circumstances, this means emptying a fully opened hot tap into the sink for up to 20 minutes per outlet to sterilise the tap.

Not only does this process require a lot of man-hours, but it also involves wasting large volumes of heated water with no guarantee that the flushing regime has been effective. In addition, there is no way of knowing whether the tap needed to be flushed in the first place. If it had been used regularly throughout the week, bacteria would not have had the chance to multiply and would not pose a risk.

Cubik’s scope was to advance the early Leocycle prototype and develop key components of a launch product suitable for the market. In addition, Cubik had to address the issue of battery life and successfully extended the prototypes operation time from 6 weeks to 12 months and beyond. The first batch of market-ready products were then field tested in local hospitals to ensure functionality and efficiency in a real-world scenario.

Water safety is one of the most common and challenging issues faced by building maintenance teams. Leocycle provides an elegant solution to a traditional problem. The system has been designed to monitor the flushing process, provide feedback on when and where sterilisation is required and confirm when sterilisation has successfully taken place. It uses advanced detection and evaluation algorithms to continuously monitor the risk of legionella, determines when an outlet needs sterilisation and alerts the user.

Under the Approved Code of Practice L8 (APoC L8) regulations, organisations at risk of infection are required to provide an audit trail. Audit trails and data collection are a vital tool for evaluating the wider risk to building occupants over time. The Leocycle system continuously logs the activity at the sink, including flushing, to provide a comprehensive compliance record for auditing and further analysis.

Speaking about Leocycle, Robin Stone said:

“Smart, connected facility systems are going through a real generational change when it comes to building management, thanks to advances in the ‘Internet-of-Things’ and embedded processing.

In addition, ACoP compliance is a major legislation concern for Facilities Managers. Now organisations have an auditable, reliable detection system which can save labour and cost in maintaining compliance. Something which will be very welcome in the current climate of austerity.

The Leocycle team is uniquely positioned as both a Facilities Management consultancy firm and as a provider of mission-critical products. We have a number of innovations we’re eager to bring to market as soon as possible, so watch this space!”

The smart, embedded device can be fitted to sinks and water basins without the need of disrupting the existing building management infrastructure, break into pipework or provide mains power.

Speaking about working on the Leocycle project, Cubik MD, Paul Mullen said:

“It was a great challenge and an extremely interesting and worthy project to be involved in. We look forward to seeing the product successfully make its way to the market.”

Systems that serve public health and safety are of paramount importance in a world of increasing risk and are of particular interest to Cubik. If you have a concept or a prototype that works to streamline current manual health and safety processes and need some assistance, contact us.

Adrian Schmieder of HiETA commented: “Cubik’s quick turn-around of a functioning PCB has sped the delivery of the project and enabled me to focus on areas of the project in which HiETA has expertise.  The project is a great success and produced valuable information even from its first use.  I am very impressed with the support Cubik provided me throughout the project, from initial concept through to PCB delivery.  I will not hesitate to engage with them again as future PCB projects arise.”


Speaking about the collaboration between Inductosense and Cubik Innovation, Founder and CTO Dr Chenghuan Zhong (Bamboo) stated: "It was great working with the knowledgeable and experienced team at Cubik Innovation. They always provide full support as well as useful and thoughtful advice to us, helping us find solutions for really difficult problems."


Geoff Jones, Aquabar Inventor: "It was a pleasure to work with Cubik on our project. Paul and Sam understood the concept at one meeting, and produced a solution filling the brief within two weeks which has enabled us to find a potential partner. We will certainly use Cubik for our production units later in the year, Many thanks."
