Skolen i Bymidten school with ventilation ceilings

Uniting aesthetics, acoustics and ventilation

"Our objective was to minimise building height while retaining as much of the original volume as possible. That is why we worked with ventilation ceilings."
Hanne Pedersen, Architect, Project Manager & Construction Economist, Kjær & Richter

Renovation and extension of the elementary school Skolen i Bymidten in Elsinore, Denmark posed a fundamental challenge. How do you modernise ventilation system in buildings from 1880 without losing floor height? By combining acoustical ceilings and ventilation system into one solution - which saves space, building costs and maintenance.  

As a result, the architects at Kjær & Richter were able to optimise the ventilation, save ventilation inlets and reduce the diameter of exaust pipe, in some places down to 350 mm – almost half the size compared to a traditional ventilation system.

  • When integrating ventilation with the acoustical ceiling, you can make the ceiling without air inlets. The fixtures in the ceiling are kept at a minimum - only the exhaust vents are necessary. Learn more about how ventilation ceilings work: Ventilation & acoustics

Besides acoustic and ventilation requirements, also aesthetics and sustainability played a key role: “We decided to go with gypsum ceilings for aesthetical reasons – as it is more in line with buildings from the 1880s than other ceilings available. And because it is our experience that gypsum simply lasts longer in schools”
