Chief Maintenance and Development Officer,
Viru Keskus

"2 up-to-date and reliable automation systems (Siemens Desigo Insight and Schneider Electric Struxureware) managing the technological systems have already been used in Viru Keskus, located in the heart of Tallinn. The technological systems of the shopping centre are managed by Ermeesia OÜ, the company providing the best service in this sector in Estonia.

In addition to the above, we have also been using the R8 Digital Operator since July 2017, making us the first shopping centre in the world to use it. What did this solution mean for the real estate owner, its tenants and administrative partners?

First of all, it was confirmed that the resource-intensive costs of Viru Keskus decreased considerably. This, in turn, enabled us to provide high quality real estate services and the associated lower general costs to our tenants regardless of the rise in energy prices.

The satisfaction of both the tenants and the administrative partners of the centre in faster and more precise detection of the problems related to the technological systems has increased. This capability enables us to prevent arising problems in communication with the tenants and any emerging issues can be solved with minimal time resource. Also, the applied artificial intelligence will mean a more efficient use of working time of the technicians and the resulting cut in costs.

It is also worth mentioning that as a result of the more comprehensive management of technological systems the operational lifecycle of the equipment is extended and the investments made are better utilized.

To sum up, it should be said that the artificial intelligence (AI) and machine learning (ML) introduced to us by R8tech are not new and imaginary for us any more, but today’s standard that will become a normality for all real estate companies by tomorrow."

Nautica Keskus

“We decided to get R8 Digital Operator at the end of 2019. The integration process went smoother than expected and within a short period of time the Analytics Module detected numerous faults and anomalies in the building's HVAC systems. We are also very happy with how active and helpful R8’s customer service has been throughout the whole process.”

Martin Kullamaa

Maintenance Project Manager,
EnerTEC Hooldus OÜ

“I am happy with the service R8 has provided to us and would recommend it to anyone. R8 Digital Operator has improved our indoor climate, lowered our energy costs and given us a great overview of the whole building thanks to the clear-cut and interactive charts and tables. The email alerts are very useful since they give us precise information about the location and nature of any possible faults or anomalies in the systems. This enables us to diagnose and fix problems much faster than before. R8’s customer service has always been very friendly and helpful with any questions we’ve had.”
