City of Lappeenranta Expands Building Ventilation Monitoring with Small Data Garden IoT Devices

Small Data Garden IoT devices have been used in properties owned by the City of Lappeenranta since 2019. Several years of experience have demonstrated good device reliability and battery life. The city is now implementing continuous pressure differential monitoring, enabling the performance of ventilation systems to be monitored in schools and day-care centres.

Monitoring pressure conditions in a building provides information on ventilation performance and on how air moves within the building and through its structures. Continuous measurement means that conditions do not need to be assessed based on a single measurement at a point in time. Instead, changes can be identified at different times of day and over longer periods.

Lappeenrannan Toimitilat Oy has several years of experience with Small Data Garden devices, and their reliability has proven to be good.

“In practice, Small Data Garden sensors have been in use since 2019. We haven’t had any problems with their reliability. We haven’t had to replace any devices because they have failed,” says Jani Pietinen, HVAC Specialist at Lappeenrannan Toimitilat Oy.

Battery life has met expectations

One of the advantages of wireless monitoring is that devices can be installed in existing buildings without extensive cabling. When there are many measurement points, maintenance requirements and battery life also become important in practice.

Based on Lappeenranta’s experience, battery life has met the expectations set for the devices.

“I’m sure many people have doubts about battery life, but with these devices there’s no need to worry. They last the five years that was promised.”

Long battery life reduces maintenance requirements and allows the devices to operate in buildings for extended periods without frequent maintenance visits.

Closer monitoring of pressure differentials in schools and day-care centres

“The main point is to enable better monitoring of pressure conditions in schools and day-care centres. A pressure differential monitoring system using Small Data Garden devices is currently being implemented.”

Continuous measurement allows property maintenance teams to see how pressure conditions behave at different times of day and how they change over time. It also makes it possible to identify potential deviations without relying solely on individual inspection measurements.

The cooperation between the City of Lappeenranta and Small Data Garden has continued since 2019. The use of IoT solutions is now expanding into another application where data from wireless monitoring is used to support the monitoring of conditions in schools and day-care centres.
