VELUX skylight modules provide maximum daylight and natural ventilation

The school was equipped with three rows of skylights dating from the 1990s, made of double glazing and aluminium frames, and included manual ventilation and smoke extraction.

The main challenge of this project was therefore to replace this obsolete structure while ensuring automatic ventilation in the building. In addition, the specification also required an integrated smoke extraction solution.

VELUX Modular Skylights ensure comfort in summer and winter. On a typical day, as summer approaches, the school’s thermal analysis results show an average temperature drop of 8.8°C between 8 a.m. and 5 p.m., thanks to natural ventilation (Freecooling). With a Uw of 1.4 W/m².K for thermal insulation in winter, double glazing creates a natural barrier against the cold. Heating consumption decreased by 5% for the entire school and by 38% for the premises directly under the skylight. Convincing results, thanks to a skylight solution that ensures energy savings and comfort for students throughout the year.

We have been working with VELUX for more than 45 years and this is the first time we have installed this solution. We were trained and assisted throughout the project, directly on the building site.

The deadline also determined our choice.

Refurbishment organised during the school holidays

The refurbishment was organised to fit in with the school's schedule, with work carried out quickly over the school holiday period. Installer Wiedemann & Fils completed the job over a six-week period (from 25 July to 1 September) in order to meet the deadline.
