Mairie Montrouge

As Montrouge’s town hall is a historic building from 1883, the domes were not supposed to be visible from town hall square. To light the rooms located in the South, it was necessary to redirect light from the North using 5 metres of extension tubes with several bends. Moreover, fire prevention regulations required a barrier to prevent a fire from entering the building.

Issue

The purpose of this project was to introduce more daylight into the town hall offices located in the old attic which only had a small round window. The town hall’s objective was to utilize the benefits of natural light for its employees and municipal representatives while also saving energy.

Solution

To meet the project requirements, Solatube Ø 53 cm with a square ceiling diffuser were proposed. Five daylighting systems were installed, two in the meeting room (with daylight dimmers) and three in the offices. Externally, to meet the project’s fire prevention regulations, a B roof (t4) solution was implemented: a one-piece metal roof flashing (11 inches) and a polycarbonate dome. Internally, an OptiView Diffuser complying with public building access requirements was used.

Customer comments

In view of historic building constraints, it wasn’t easy to bring natural light into our office. Thanks to Solatube’s daylighting systems it was possible and the employees and municipal representatives of the town hall are very satisfied.
