Bureaux Septeo : natural light, brise-soleils and design
Septeo in Montpellier
A collaborative project for an architectural success
The new Septeo office building located in Lattes – near Montpellier (Hérault) was inaugurated in June 2018. More than 18 months of work and construction were required to complete such an impressive project; it was designed with a pixel pattern façade with curves and “random” brise-soleils to give the impression of an in-motion matrix.
Among all the projects, this innovative design imagined by the AMG Architects from Montpellier has been Septeo’s favorite. The operation implies 9,000 m2 of floor surface and is composed of 4 two-stories buildings linked together with 3 covered courtyards. Most of the roof is equipped with photovoltaic panels to respect the BEPOS label; the buildings’ structure is made of cladded wood type Eternit. As the main façade is located near the road, the acoustics were one of the biggest challenges; it required a bitumen design equipped with various brise-soleils. An Alucobond cover will equip the curved part of the roof.
The architects decided to focus the natural light input and soundproofing on the peristyle of the building, due to its central role in the building. A glass-roof, patio doors, and a garden will enhance this central point of the building to increase the wellbeing and comfort of its occupants.
The roof is equipped with skylights with a natural smoke extraction function to favor natural light inputs within the buildings. The staircase and other parts of the offices are equipped with five high-tech smoke vents: devices with thermally-broken profile with pneumatic mechanisms and a double-glazed infill with longitudinal brise-soleils. Such solutions and design let a maximum of natural light in the building during summer and winter while suppressing the glaring effects and preventing the building from over-heating. The Bluesteel RPT will also give the building an optimal insulation performance, and the griddles will secure the location.
"Climates, seasons, sounds, colors, obscurity, light, elements, food, noise, silence, movement, rest – everything reflects on our soul, machine.” (Jean-Jacques Rousseau)
To make roof access easy and reduce the noise of rain on the roof and its smoke vents and skylights, the Bluesteel Pass are equipped with aluminum hoods. The occupants of the offices have confirmed that this design limits the noise effect from rain.
Other more classic skylights have been installed in other parts of the buildings, which may be less frequented; it consists of Bluesteel devices with manual mechanisms and 10mm opalescent polycarbonate infill.
In conclusion, we can assert that the new Septeo offices are the reflection of a dynamic, innovative, and leading company.
