In order to make the building more transparent and open, the “Atelier Barani” opted for a system of fixed external sunbreakers made of opalescent glass.
These glass slats are distributed vertically and horizontally, according to the different exposures of the building’s façades. This principle guarantees the transparency of the facades.
The depths of the opalescent glass sunscreens have been dimensioned, per façade, according to the path of the sun, in order to prevent the sun’s rays from penetrating in summer and to diffuse the luminosity inside the spaces.
The role of SADEV
SADEV’s teams worked from the prescription to the delivery of the glass slat holding system, validated by obtaining an ATEX by COVERIS. Some of these sunshades can reach a depth of over 1.4 metres.
The building is developed on 6 floors, where it will host a set of offices. The ground floor is dedicated to the activity of the Caixa de Depositos bank, as well as a common area, a business center, a shared work space, an auditorium and a cafeteria.
The role of SADEV
To meet the different characteristics of the facade, SADEV developed «minimalist» technical solutions dedicated to «firefighter access» called firefighter openings, without frames.
The OPs – Opening / pivoting / + smoke extraction with glazing 1800 mm high x 1000 mm wide on a minimalist pivot, Marceau project.
The OP-SADEV stapled systems adapt to the architecture and the architect’s plan, letting in a maximum of light thanks to the low-profile rooms (max. height 200mm visual).
Our fire doors are tested according to the 300 cycle standard.
This tower is located in the east of Monaco, in an essentially residential area, near the sea.
It is made up of 29 floors (24 floors + 5 underground levels) including 73 apartments, a Family Center, a spa, commercial premises, three swimming pools, two of which are private on the roof of the building, and an underground parking lot with 200 spaces. Watch the project video here
A SUSTAINABLE BUILDING
The building, developed by the agency Wilmotte & Associates integrates the principles of sustainable development, it was designed to offer an environment-friendly architecture.
In particular, the architects wanted to bring in as much natural light as possible into the living spaces, without hiding the sun’s light from the neighboring buildings. In addition, its compact shape enables two apartments per floor, with their own private balconies.
SADEV’S ROLE
SADEV provided 2400 linear meters of SABCO curved guardrails. Different radius, from 5 to 10 meters were realized.
These SABCO profiles have been tested to withstand ultimate winds of over 290 km/h (4200 pa). To resist the high wind loads that a tower of this height located by the sea can encounter.
The new headquarters of the Saint-Gobain company was recently built in the heart of the “La Défense” district in Paris.
This tower, which rises over 44 levels, was designed by the Valode & Pistre architectural firm. It is distinguished by its remarkable shapes, inspired by a crystal found in the natural environment.
The building meets the challenges of “La Defense” in terms of construction. Due to the complexity of the site and it’s height, the societal issues and quality of life in a building of this magnitude make it an example in terms of energy performance.
Light is the central focus of the project
The building, assembled from all these glass panels, changes according to the exposure and the light, between transparency and reflection. This material was chosen for its ability to provide maximum light into the building and for the employees’ well-being.
The structural bolt facade technique was selected to highlight strategic locations such as the base and the top of the tower. This solution is perfect for large glass dimensions and avoids the use of profiles and lightens the whole structure while guaranteeing the best visual aspect and optimization of the light contribution.
This stapled glass facade has allowed the realization of a plant greenhouse at the top of the tower, where the climate is temperate in all seasons.
A technical project
During the design phase the tower head with Eiffage and the tower base with Hefi, SADEV used all its know-how to answer the technical problems (dilatation, high load resumption…), from the design study to the manufacturing of a structural bolt glass facade system unique to the project.
THE TOWER HEAD
This glass lozenge that seems to be floating above the tower is the most complex part of the structure.
Due to its geometry and the altitude where it is positioned.
At this height everything takes on proportions of a different magnitude: the wind, the deformations of the materials and the building…
Thus, maintaining 300-kilogram glass panels at a height of 170 meters requires mastery of the design studies, the various calculations, the manufacturing of the products and the installation on site.
Thanks to its technical approach, SADEV had to solve specific constraints by developing specific fasteners to meet the constraints of this structural bolt facade.
The characteristics of the S3030 L fastener made it possible to meet the high structural loads.
THE TOWER BASE
This glass cube is the building’s showcase.
This showroom is a real skylight, which displays Saint-Gobain’s products and innovations. SADEV designed and built the fasteners and swivel fittings that hold the suspended structure and the glass panels of different geometries.
