Due to the ongoing climate change, the issues currently in focus are the reduction of CO2 emissions into the atmosphere and sustainable construction. The search for ecological alternatives to traditional building structures that will reduce a building’s carbon footprint seems to be a desirable direction of modern construction development. At present, the first projects of office buildings that use cross-laminated timber as the main construction material are being completed, which can have a positive impact not only on the environment but also on the users of the building.
