DINLabs Findings Event

Aptly named A Compliance Game-Changer – The Digital Alternative to Manual Measurement the most recent Proptech Innovation Network’s (PIN) DINLab Findings event took place last week with some very positive outcomes from it.

In the summer of 2021, PIN ( Disruptive Innovators Network ) and Plexus Innovation undertook a DINLab with three housing providers to explore remote legionella compliance testing and water systems management.

The three social housing providers Selwood Homes, Loreburn Housing Association and Sovereign Housing all had different reasons for trialling the IoT remote technology called GUARDIAN®. From issues with integrity of manual compliance data, to adequate water flushing, issues with water system condition and access to properties, the three all had problems that Plexus Innovation knew GUARDIAN® could assist with.

Ian Murray, Managing Director Plexus Innovation, a passionate advocate on how technology can benefit landlords and tenants presented an overview of the finding from the data collected by GUARDIAN® during the 12 weeks of the DINLab. From identifying that temperature settings were set too high, to leaks, taps left running and failing systems or manpower. The level of GUARDIAN®’s data was impressive. Feedback from participants on the DINLab included

"We are now looking at rolling out implementation further - there's plenty more to come." "We are saving up to five days a month on admin resource…and have the support of our executive team."

“It now has the full support of our entire team and executive board, and we look forward to rolling it out across the rest of our properties in the next two years.”

“Helped to support us on our journey to Net Zero by identifying that our water heaters were operating inefficiently. It highlighted three hot assets that were short of the compliant temperatures that were a potential scald risk. We can instruct our remedial team more quickly to go and fix the issues picked up.”

“It was so easy to install…”

“We went into the pilot to automate our water flushing and legionella compliance as much as possible, we get weekly reports which we find really useful and remove the need to process an admin heavy data report. We are now only flushing those assets that are required, reducing time that technicians are open outlets. The data gives us a better understanding of our TMV performance and whether there is a scalding risk – we had quite a few highlighted that we had no idea about.” Existing customers of Plexus Innovation also attended the event to share their experience over the course of their association with GUARDIAN®. They said: "We have used GUARDIAN® for three years now and it has helped us manage water system compliance throughout that time successfully, including during the pandemic. It also clearly identifies early issues that we would just not know about until they presented a much larger problem."

The session closed with all the GUARDIAN® trial collaborators confirming executive and cross function buy in and an intention to implement more widely. All are also willing to talk to other providers about their experience.

Ian Murray concluded:

“Thank you to PIN and the sector participants for this opportunity to delve deeper into the social housing sector and to test GUARDIAN® to its limits in such different environments, tackling different challenges. We had no doubt of its performance ability, but this has given us the chance to showcase to the entire sector that there is a better way, the GUARDIAN® way, to do things.”

GUARDIAN® function includes measurement of temperature, CO2, humidity and water system monitoring and control, enabling insight driven decisions, reliable compliance reporting and alerting to health risks or failing assets that otherwise may not be known about.
