In today’s digital era, the Telia Helsinki Data Center stands as the largest open data center in Scandinavia, marking a significant achievement in the field of innovative data management and eco-friendly technology.

Data centers have been known for high energy consumption, posing a stark contrast to the sustainability goals prevalent in today’s business environment.

Addressing this, Telia aimed to develop a data center environment that balances robust functionality with environmental consciousness. This ambition set the stage for numerous challenges, from managing the significant energy consumption to ensuring flexibility, safety and material efficiency during the construction and operation phases, while also achieving recognized environmental certifications.

Hilti joined as a key partner, not merely as a supplier but as a strategic ally contributing more than tools and solutions. From the beginning, Hilti and Telia worked together closely to create a data center that combines advanced technology with thoughtful environmental practices.

Vision & Challenges

The Telia Helsinki Data Center was designed with an ambitious goal: to manage vast amounts of data while maintaining an environmentally friendly approach. More than just a data repository, it’s an example of combining technology with environmental awareness, especially notable in a region recognized for its advanced technological solutions. The project faced several significant challenges:

Managing growth
Figuring out how to manage a growing amount of data without overusing natural resources was a major task for the team. It had to find innovative solutions to minimize energy use and emissions.

Using waste heat wisely
Telia wanted to make sure the heat produced by the data center was used for the benefit of nearby communities.

Handling digital waste
Also, Telia wanted to manage the increase of data and to reduce digital waste, which is crucial for maintaining a reliable, high-quality service.

Keeping data safe and accessible
The team had to ensure the data center was secure, reliable and easy to use, to earn client trust and make sure services run smoothly.

Balancing economics and environment
Telia and Hilti wanted to strategically align financial sensibility with environmental goals.

In addressing these challenges, Hilti stepped in with a clear vision: to merge technological advancement with environmental care.


As a strategic partner and innovation enabler, Hilti’s role was crucial in addressing the Telia Helsinki Data Center’s challenges, driving both environmental care and operational efficiency. Key measures included:

These solutions were integral in the Telia Helsinki Data Center’s achieving LEED Gold certification, which stands for “Leadership in Energy and Environmental Design.”

Achieving LEED Gold

A key moment in the project was the integration of Hilti’s cooling solution, which ensures energy-efficient operation. This not only enhanced the data center’s functionality but was also crucial in attaining LEED Gold certification, highlighting the joint commitment of Hilti and Telia to responsible environmental practices.
