Exactly the right amount of fresh air 

850 m² rectangular and 2,250 m¹ round air ducts for student housing The Fizz

With The Fizz, 394 sustainable student housing units will be added to student city Leiden. The special design by Kokon Architecture & Urbanism consists of two building parts, connected by an air bridge. In combination with various study rooms, washing and fitness areas, meeting places, a communal courtyard garden and shared bicycles, this not only creates a miniature campus, but also a very pleasant living environment. The air technical systems from Schilt Bedrijven also contribute to this, providing exactly the right amount of fresh air.

The air technical installations are produced, delivered and assembled on behalf of Linthorst Techniek, with whom the business units Schilt Luchtkanalen and Schilt Luchttechniek have already realized various student residences. As an example, business development manager Leo 't Jong mentions residential towers The Cube in Utrecht Overvecht and Fibonacci in Amsterdam. "In Leiden, too, we have already been involved in the preparatory phase," he says. "Our order included about 850 m² of rectangular air ducts and 2,250 m¹ of circular air ducts in galvanized steel, part of which is insulated with mineral wool." The air ducts run across the roof and down through the technical shaft, explains operations manager Marco ter Horst. "On each floor, branches were made on the left and right to the 394 homes. This size in particular made this project challenging." All air ducts in The Fizz meet airtightness class Luka C and cleanliness class L. 50 mm Rockwool, finished with 1 mm aluminum (Stucco) cladding, was chosen to insulate the approximately 385 m2 of roof ducts.

Following the air ducts, Schilt Bedrijven also provided the TROX components for The Fizz. As an example, Ter Horst mentions the variable volume controllers (VFC dampers) with servo motors (E03). But also the fire dampers, dampers and rosettes. "Schilt Luchttechniek is the exclusive stockholder of TROX in the Netherlands. This allowed us to deliver the above components just-in-time to the construction site. A piece of service that benefits the progress of the project for our technicians, but also for other parties. Our project and assembly management continuously monitors planning, delivery of goods, assembly progress and cooperation with third parties on the construction site. Because we have influence over a large part of the chain ourselves, a lot of time is saved. As a result, we were able to deliver our work in January and exactly on schedule."

Thanks to the variable volume controllers with servo motors, the young residents of The Fizz can control their ventilation in three positions, says Ronald Ruisch, project manager at Linthorst Techniek. "This not only complies with the requirements of the Building Code, but the students also benefit from healthy air and optimal comfort."
