Decathlon La Valentine: NSHEV, vaults with brise-soleils and PCA Pearl Inside installed on the roof
Located in the neighborhood of La Valentine in Marseille, this new Decathlon store is the 11th in the Bouches-du-Rhône region. With a company culture focusing on sports and performance, the brand made a relevant choice in the materials for this new construction; the first Decathlon store with multiple levels, HQE certified, is the biggest in the region.
Opened in 2017, the store has been built in accordance to the local environment, available land in this area being less common, and therefore made the choice to focus on a vertical construction.

The store, starting on the 4th level, has been designed to favor natural lighting of the area thanks to clever glazing systems. The store itself level is located above 3 levels of parking, for a total floor surface of 17,000 m2 and 8,000 m2 of land with a simple architectural design. The installation of photovoltaic power plants on the roof enables the building to use renewable energy (extract from destimed.fr).

The natural light is an important part of the architect project, which has designed the building so that the roof plays a key role for smoke extraction in the event of a fire, but also for comfort, aesthetics and energy management requirements.
Here are the details of the installation of skylights on the roof of the store.

13 vaults of 3000 X 6000 type Bluevoûte Therm. The devices are equipped brise-soleil type Voile-Dôme and a classic PCA 20 mm (Ut = 1,7 W/m².K / Tv = 35 % / g = 0,2) infill.
21 NSHEV skylights type Bluesteel Therm Pneu with dimensions 120/300, 120/120 and 100/100, and one skylight Bluesteel Therm Pass for roof access.
The NSHEV devices and skylights benefit from a PCA 20 mm Pear Inside technology (Ut = 1,9 W/m².K / Rw = 28 - 0 ;-2 - Db / Lia = 64 Db / Tv = 43 % / g = 0,45).

In conclusion, this HQE building integrates, through its roof, a natural light system enhanced with brise-soleil screens dissociated from the glazing. This type of installation prevents the direct glaring effect inside the building and protect from the sun-effects in summer but let the heat in during winter. The need for air conditioning or heating systems is reduced, and the building benefits from energy savings. The installation also includes the polycarbonate Pearl Inside technology with glass microbeads to improve the soundproofing inside the building, and its aesthetics.
