Timber in the structure: lower embodied carbon from the building

As electricity becomes renewable, the building accounts for a growing share of a data center's climate impact. Data centers with cross-laminated timber structures have already been built in Sweden and the US. This is one of the few technology areas that lies entirely within the developer's responsibility.

What the development involves

EcoDataCenter in Falun has built its facility with a cross-laminated timber (CLT) structure instead of steel and concrete (EcoDataCenter). Microsoft is building data centers in Virginia with cross-laminated timber in the structure (Microsoft, October 31, 2024).

What benefits are documented

EcoDataCenter reports up to 60% lower embodied carbon based on its own life cycle assessment. Microsoft estimates 35% lower embodied carbon than steel and 65% lower than precast concrete. Both figures come from the companies themselves.

What it could mean in Sweden

Sweden has a strong timber construction industry and experience of large timber structures. Lower embodied carbon can become a clear argument for investors and customers who report their emissions.

What we are investigating

How fire protection and insurance are handled. Whether the floor slabs can carry the loads of liquid-cooled racks. How the life cycle assessment can be made comparable between projects, and whether a pilot project can demonstrate the benefits in practice.
