Triodos Bank believes it is important that its buildings provide a pleasant, stimulating space for its co-workers to work, and that they have a minimal environmental footprint. This applies to all of its branches. The materials and products used in all its offices must pass strict environmental tests. The total floor area occupied by Triodos Bank increased by 23% in 2010. This is mostly because of opening two new offices in Spain and renting an extra building in the Netherlands for the Dutch branch.
