Since 2016, the office building of T-Systems Netherlands in Vianen has been supplied entirely with green energy (100 %). In 2019, the company will move from its office building in Vianen to Utrecht. This building has a class A label. The offices in Heerlen and The Hague cannot be supplied with green energy due to the fact that there are other tenants in the building and to the strategy of the owner of the building.
In 2017 and 2018, T-Systems Netherlands focused on improved efficiency for the floor space of its office buildings. A significant decrease in floor space will be achieved as result:
The main focus for the company's data centers in 2018 was the significant decrease in energy consumption. In 2018, 21% less energy was consumed in comparison to 2017. This enabled T-Systems Netherlands to build on its achievements in previous years: in 2017 28% less energy was consumed in comparison to 2016, and in 2016 13% less energy was consumed in comparison to 2015. This was achieved through asset refresh (lifecycle management), decommissioning, and data-center consolidation.
