The Majunga Tower was developed in accordance with high energy efficiency goals. From its design and development right up to its operation, this building stands out through its energy performance and the technological innovations it provides to users. Special attention was paid to the materials used and to reducing sound pollution. The tower’s energy efficiency is unparalleled among skyscrapers, and for the first time, natural air can be accessed through comfort opening frames and by visiting outside loggias on each floor. The tower also features a 250 m² photovoltaic power facility and a rainwater recovery system.
Egis is worked on the tower's structural studies, which included overall and detailed execution calculations, 3D modelling, ground-structure interactions, dynamic behaviour, load lowering, detailed foundation slab, wall and post calculations, subsidence prediction, etc. Egis was also in charge of environmental engineering as regards the project’s studies and BREEAM certification process. The building has also received HQE® certification.
> Allianz Riviera, a positive energy stadium
An ambitious architectural project in the Saint-Isidore area of Nice, the new "Allianz Riviera" stadium is a positive energy building. Inaugurated in September 2013, it will be one of the host stadiums for Euro 2016.
This is a flagship project for sustainable development and technical performance: mass use of wood, geothermal energy for producing hot and cold air, natural ventilation, water recovery for watering the lawn and supplying the toilets, and implementation of a photovoltaic power system with a surface area of 8500 sqm, making this an eco-positive stadium.
> La Nef: positive energy offices and social housing
The restructuring of the former postal distribution centre in Tours has resulted in a multi-functional building called La Nef. This operation is ambitious in terms of size and design and includes 6,000 m² of office space; around fifty apartments for purchase, including seven houses positioned on the roof; and social housing for rental and basement car parks. This is the first disaffected industrial area to be rehabilitated in the Centre-Val de Loire region in accordance with RT 2020 requirements.
