Natural light study and Bluevoûte Therm: a textbook case

“Compliance with the EN 17037 standard, by providing natural light of 300 lux over 95% of the space, and this for 50% of the working time. Upstream, during the reflection on the construction of the new Tellier Brise-Soleil buildings in Chemillé-en-Anjou (FR-49), the recommendations instilled by the EN 17037 standard were followed.

The same was true for protection against glare and exposure to direct sunlight, other additional and normative recommendation criteria in this text. Inaugurated in the summer of 2022, the Tellier Brise-Soleil buildings now represent a very beautiful showroom and an ideal site for monitoring the quality of the products of the Adexsi Group, of which Bluetek is a part.

Bluevoûte Therm running skylights for efficient and controlled natural light

These are not less than 16 skylights Bluevault Therm which were installed on the roof. Here are their numbers and dimensions:

9 Bluevoûte Therm rope units 3 m X 5 m long,
5 Bluevoûte Therm rope units 3 X 8 m long,
2 Bluevoûte Therm rope units 3 X 25 m long.

These thermally improved vaults are equipped with a PCA with a thickness of 16 mm integrating the technology Pearl Inside. This technology allows the contribution of controlled natural light which reduces the greenhouse effect, supplemented by thermal and acoustic performance. This filling also brings a nice design touch with its crystalline effect.

Fire safety, ventilation and cooling of premises

Bluevoûte Therm skylights are equipped with Exuplus Elec openings. These modules for the smoke extraction allow, in the event of a fire, to ensure their function of NSHEV. The openings also allow a ventilation of the building automatically or manually.

In addition, the workshops benefit from Air Cooling by Evaporation, i.e. a process called adiabatic, with diffusion by textile ducts.

The employees of the Tellier Brise-Soleil factory say they are satisfied with this principle of distribution in natural light, just as they are of summer comfort.

study of natural light

Created and made available by Bluetek on its website, the light calculation tool provides a simple and guided way to obtain a Daylight Factor (FLJ) in line with standard EN 17037.

The web tool allows a simple calculation, with upstream certain questions such as, for example:

The percentage of autonomy in natural light desired and the number of lux.
The type and precise dimensions of the building.
Performance options.

Downstream, the tool allows a selection of products, a clear simulation and a summary of the results.

For the study of the Tellier Brise-Soleil buildings, the choice of products was made in such a way as to combine overhead natural lighting on the facade (light strips) and long and short vaults on the roof. The latter have been distributed in order to best homogenize the diffusion of natural light inside the workshops. In the project as a whole, the piloting and management of artificial light allow a rationalization of the equipment.
