Triodos Bank’s head office in Driebergen seamlessly blends architecture and nature. This holistic, sustainable design enhances wellbeing and biodiversity. With expansive green roofs, the building embodies Triodos Bank’s vision of harmony between people, planet, and prosperity.
Connecting Building and Landscape at Triodos Bank
Multifunctional Surface
Every component of the roof plays a role. Rainwater is buffered, and nature is afforded space to flourish.
Climate adaptive design
The roof stores water during heavy rainfall and helps cool the surroundings during summer heat.
Biodiversity in the Built Environment
A diverse planting plan attracts pollinators, birds, and native insects. This turns the roof into a thriving ecosystem.
Triodos Bank’s new head office in Driebergen, the Netherlands, has now become an internationally renowned concept. Nature and civilization come together in this office building. This is reflected in a holistic concept, in which building and nature form a harmonious whole. Something that benefits both people and nature. To create the green roofs of this extremely sustainable project, around 16,000 square feet of Sempergreen Sedum mix mats have been delivered, as commissioned by Van Helvoirt Groenprojecten.
Ingenious water collection system
The green roofs have aided Triodos Bank and RAU architects in accomplishing their goal: to link Triodos Bank’s headquarters to its surrounding nature. Moreover, the green roofs possess a water-buffering capability, which averts the overburdening of the sewage system due to heavy rainfall. Surplus rainwater is gathered in a rainwater tank. When it is full, it overflows into a nearby pond. Should the pond also reach capacity, the water percolates into an infiltration trench situated on the estate. There, it can gradually seep into the soil. Thus, the building integrates into the local water cycle.

Inseparable Bond with Flora and Fauna
The plants on the roofs provide birds and insects with a healthy and pleasant living environment. Flying insects, in particular, benefit from the green roofs. They form an insect highway and function as connecting bridges between the surrounding nature on the estate. The fact that the building was constructed close to the afforestation also helps here. In addition, construction has ensured that the flora and fauna on the estate are not disturbed. For example, nest boxes have been installed, spaces for amphibians have been created, and amber lighting has been installed. The latter ensures that the flight paths of bats are not disrupted.
