Soprema Entreprises in Rennes: on the road to positive energy premises

The New Horizon of Soprema Entreprises in Rennes

Since its creation in 1969, Soprema Entreprises has always sought to innovate. Located in the South East Industrial Zone of Rennes, the company began its life in prefabricated buildings. But today, the firm is looking to the future with an eco-responsible vision.

The company has evolved, and with it, its workforce. Faced with expansion and successive recruitments, Soprema felt the urgent need to modernize its facilities. This is how the idea of a positive-energy building emerged, reflecting the company's expertise and commitment to sustainable development.

A Revolutionary Building: Metal Frame & Positive Energy

Soprema Entreprises isn't just a player in the construction industry; it's a pioneer. The company has developed a unique process for creating low-energy buildings (LEB) with a metal frame. This innovation, a first in the industrial sector, addresses the challenges of thermal insulation and airtightness.

Thanks to its advances, Soprema Entreprises was able to experiment with this technology in Brest, combining offices and warehouses under one roof. But in Rennes, the ambition goes even further: a fully commercial building, while retaining certain key features such as the roof equipped with flexible photovoltaic panels.

The promise? A model that could serve as a benchmark for various types of construction: industrial, commercial, or residential.

Photovoltaic Innovation: The Transition Towards Positive Energy

To transform this low-energy building into a marvel of positive energy, a photovoltaic roof is essential. SOPREMA already demonstrated its expertise with the SOPRASOLAR® system in 2006, which integrates flexible photovoltaic panels with bituminous waterproofing.

But in Rennes, innovation doesn't stop there. The company is currently working on a roofing system where rigid photovoltaic panels will become the roof itself. This advancement will be tested for the first time on the Rennes project.

The Quintessence of Soprema Enterprises

This building will not be limited to a single innovation. It will showcase Soprema's potential, combining:

• Various claddings, from the most basic to the most luxurious.
• Different waterproofing methods, including the Sopranature® plant system.
• Photovoltaic systems on roofs and facades.

To bring this vision to life, Soprema Entreprises in Rennes partnered with experts: the architectural firm NICOT, ACE Ingénierie, and the design firm EXOCETH. All are united by a common goal: to create an exemplary and sustainable building.

Synthesis

Soprema Entreprises in Rennes is poised to redefine sustainable architecture with a positive-energy building that combines technological innovation with an eco-responsible commitment. This initiative reflects not only the company's vision but also its ability to transform the construction industry.
