Triodos Bank – Zeist

The Triodos Bank office in Driebergen is one of the Dutch paragons of sustainable and circular building. The glass facade is the eye-catcher of the building. Octatube Services is responsible for maintenance and repair of this highly transparent façade.

Sustainable

Sustainability architect Thomas Rau designed the transparent glass façade to provide an optimal view of the nature surrounding the building. The façade is self-supporting and consists of 1280 glass panels that are connected via a steel construction to the building’s unique sustainable wooden structure. This ensures the desired transparency. For maximum insulation value and to meet the sustainability ambition, triple glazing with a specific glass coating was used. Octatube completed the facade in 2019.

Circular

The design takes into account that almost the entire building should eventually be disassembled and that all materials can then be reused in other places and ways. All components and materials are therefore registered in a Madaster materials passport so that they can always be identified for reuse. The glass, for example, is traceable down to the silicate from which it is recorded where it was extracted. The building has the highest BREEAM-NL certification: Outstanding.

Maintenance and repair

As part of its ongoing commitment to specialist maintenance, Octatube Services replaced a glass panel on the 3rd floor, four years after completion.
