There’s a great amount of money to be saved in public buildings, businesses, and institutions. Something, the use of ReMoni’s wireless IoT sensors demonstrates in a project, run by Danish Energy Management, the Technical University of Denmark and Aarhus University
Fact-based decisions are in high demand when it comes to energy optimization in private as well as public companies and institutions. This is something Jakob Nørby, who works as a market manager for energy innovation at DEM (Danish Energy Management) explains:
"We want our customers' decisions to become more fact-based than the case is today. I believe that it will lead to more and more robust cases for energy optimizations/renovations."
As part of the project called E-snap, supported by the Danish Energy Agency, a handful of ReMoni clamp-on IoT sensors was installed in a local daycare center in Aarhus. The purpose was to recalculate the saving potential of, among other things, the heating system in the building. The sensors measured certain temperatures on the district heating pipes, which on the surface otherwise worked as they should. However, after the sensors were set up, the measurements showed that the heating system did not work properly:
"Our needs typically arise when we suspect that technical plants do not perform optimally and thereby have a huge energy loss. This suspicion will be able to be confirmed by means of, for example, IoT sensors," explains Jakob Nørby.
The measurements in the daycare center clearly showed that improvements were needed. Jakob Nørby says that the starting point for the project was focused on the ventilation - which should only run in the opening hours. But this also turned out not to be the case.
Monitoring pays off
After the sensors were set up, the return of investments was cut in half.
"We knew there were some errors in the technical installations. Sometimes it just does not work as expected. But we did not know that the case was as strong as it actually turned out to be," explains Jakob Nørby, while emphasizing that he is an impartial advisor and that there might have been other sensors than ReMonis that could be used in the project. However, when the choice fell on ReMoni, it was because of the complete solution. Everything works together from the start and when the sensors are mounted on the outside of the cables, everything else runs automatically.
Jakob Nørby sees great possibilities in ReMoni's solution. "In fact, there’s not a building we cannot find savings in. Office buildings, public institutions, and factories - just to name a few. We can quickly and easily get an overview of the energy situation. And at a much lower price than we have seen in the market so far."
