A dynamic facade with a unique atmosphere

Construction of an administration, logistics, and storage center

QoQa, a collaborative e-commerce company that works with Swissroc SA and Arveron SA, has outgrown its space and has built a new 9,000-square-meter building near the Bussigny station to house its own employees and several partner companies.

The new building was designed for a modern work culture and offers everyone the opportunity to rent free space through a special app. The original goal was to address the company's growing lack of space and bring together all administrative and logistics employees in one place. At the same time, it was also intended to redefine coworking by promoting dialogue between the various SMEs and startups located in the complex. The building is designed in the American style and emphasizes employee comfort. That's why it also houses a restaurant, a fitness room, sound and video studios, and a health center. In addition, part of the roof is designed as an accessible terrace.

A concept inspired by the American model

This building is a kind of Silicon Valley blueprint and was designed as a place of exchange with a high level of well-being for everyone who works there. At the center of the concept is the central courtyard, which reveals relaxation areas in its heart. A metal staircase integrated into the exterior facade provides access from the different levels and terraces, allowing for great flexibility in the design and the supply of natural light to the rooms. There are terraces on the third and fourth floors that can be used for events.

Modern energy concept

The high insulation of the facade, with a global U value of less than 0.75 W/m², represents an important added value for the overall energy concept and made it possible to dimension the low-capacity heat generation in combination with geothermal probes and heat pumps. The maximum optimization of the roof space also favored the installation of photovoltaic modules to minimize electricity costs. Textile solar protection systems also contribute significantly to the climate concept, ensuring an effective reduction of solar gain. In this case, the requirement was to ensure very effective solar protection that also allowed an uninterrupted view of the external environment.

Zipper systems with special Soltis fabric

The Soltis Veozip solar protection fabric from Serge Ferrari, specially developed for this application, has been selected for the zipper systems of the VSe system from Schenker Storen. It is manufactured using the special production method "Smart Yarn Technology", in which the high-strength polyester yarn is coated individually with PVC and then woven. A woven structure that is perfect for zipper systems, ZIP systems, because it provides flexibility and absorption reserves in the material. Thanks to the integration of the raw thread, Veozip meshes are also aesthetically pleasing for their very textile character and soft texture.

Strong wind stability

As the building is located in a peripheral location and on elevated ground, it was also essential that the system had strong wind stability. Thanks to the special fabric structure and a high-strength polyester thread specially developed and manufactured by the Serge Ferrari Group, Soltis Veozip is also well suited for windy locations. This allows it to meet the high demands placed on a zipper system, such as uniform tension, absorption, and stability in the event of wind exposure.

A particular advantage of this special fabric for zipper systems is that it is particularly effective at reducing solar energy across the entire color spectrum, even with light colors. In contrast to the eye-catching cinnamon-colored railings on the exterior facade, the milky, macadamia from the wide collection of 15 colors was chosen. Despite the light color, this fabric guarantees a solar gain of only 3% according to ISO 52022-3 (type D glazing - method 2).

Another important criterion for choosing Soltis Veozip was the visual comfort of employees. When the blinds are down, the goal is not to create a cramped space, but to maintain a wide view of the surroundings and a high level of light transmission. The fabric guarantees this thanks to its extraordinary transparency, which allows an almost unlimited view of the surrounding landscape. At the same time, it offers the necessary protection against glare, which is especially important for the numerous computer workstations in the building.

Finally, decision-makers also awarded the product additional points for its safety and environmental certifications. Soltis Veozip is free of phthalates and also has the Greenguard certification, making it ideal for use in sensitive areas such as daycare centers, hospitals, and nursing homes. This material also has the Swiss Eco-Bau label, making it suitable for use in Minergie-Eco construction. There is also a high level of safety in terms of fire protection, as this solar protection fabric is classified according to Euroclass B-s2,d0.
