Estonia to power its largest business campus with AI

Estonian business campus Ülemiste City in Tallinn is set to introduce an AI-based energy management system in all its office buildings, powering 78,000 square meters of real estate. The system will help to achieve the desired indoor climate with minimal costs.

Ülemiste City, the largest business campus in the Baltic States located in the Estonian capital of Tallinn, is set to introduce an artificial intelligence-based energy management system in all its office buildings.

Energy, reinvented

By utilising real-time data, the AI can make informed decisions on how to distribute and conserve energy more efficiently, ultimately reducing overall energy costs and the environmental impact of the business campus.

The agreement was signed between Mainor Ülemiste AS, the developer of Ülemiste City, and technology company R8 Technologies. The energy management system will be introduced in all commercial buildings managed by Mainor Ülemiste, resulting in significant energy savings in a total of nearly 78,000 square meters of office space.

According to Ursel Velve, Chairman of the Management Board of Mainor Ülemiste AS, efficiency and sustainability is already a standard in the industry, already implemented here. For example, the recently completed building, named after pharma scientist Alma Tomingas, was designed and built to meet the requirements of the LEED gold certificate for energy and environmental sustainability. The building also features solar panels and a district heating and cooling system that use green energy, powering the tropical garden inside.


“Tenants also expect that the office space offered to them is resource-saving,” explained Velve. R8’s artificial intelligence-based energy management system will help to achieve this. Currently, the digital operator is used in two objects with a total area of 40,000 square meters, and three more buildings with a total of 38,000 square meters of office space will be added soon.

Big savings at minimal costs

The R8 Technologies solution allows Mainor Ülemiste to collect and systematise consumption-related data, and make decisions regarding the design and construction of future buildings. It already has a proven track record as R8 Digital Operator already works in 19 countries with 2M+ square meters under management.

Siim Täkker, CEO of R8 Technologies, explains that the goal of intelligent energy and indoor climate management software for commercial buildings is to achieve the desired indoor climate with minimal costs. The tool is created for the customer so that the building operates efficiently and all the hidden possibilities are utilised with automatic data processing. “Adopting the tool is simple, fast, and does not generally require additional investments,” adds Täkker.

Ulemiste City plan by 2025 

The use of AI is yet another step that Estonia has taken to become more energy efficient. For example, the city of Tallinn has saved over €1.1M in energy costs in just three months by implementing energy-saving measures, reports city administration.

An analysis of the implementation of the energy-saving measures by the City Property Department showed that the city’s institutions reduced electricity consumption by an average of 18.2%, gas consumption by an average of 12.9%, and central heating consumption by an average of 7.7%.

With cutting-edge technology making its way into commercial estates, the country is now positioned to reach its energy savings goal even faster  – Estonia aims to become 100% renewable by 2030.
