Sky One in Toulouse by Atelier(s) Alfonso Femia

Atelier(s) Alfonso Femia is to build two office buildings with a combined floor area of 11,402 m² as part of “Dessine-Moi Toulouse”. This development, named Sky One and led by EM2C Groupe, could target the E2C1 level of the E+C- label. The design team also includes Ginger Burgeap, E-Nergy and Woodstock Paysage. See also:

Context and site

The project sits on the edge of Toulouse-Blagnac airport, in Blagnac. Besides the noise generated by the airport, the site is distinctive in that it is made up of two parallel plots.

Although a public passage divides the site, the architects wanted the two buildings to engage in a dialogue without designing twins. The result is two different material treatments and two different façade grids. The buildings nonetheless respond to each other through similar massing, with floor areas of 6,020 m² and 5,382 m².

The first building is wrapped in glass: smooth on the elevation facing the airport runways, it becomes rougher at the heart of the site, with window frames and cladding panels set at playful angles. The second building takes a more restrained, mineral approach, with tall columns emphasising its verticality.

Sky One will house a data centre as well as a Basic Fit fitness club with its own gym. A work café will complete the base of the scheme. Of the 8,510 m² of offices planned, 5,000 m² will be given over to a coworking space operated by Régus or Sunwork. The energy given off by the equipment will be used to heat the premises.

Asked by Actuarchi about their environmental choices, the architects replied: “We plan to supply the building primarily with renewable energy drawn from the site. Thermal energy (heating and cooling) will be provided by heat pumps, which will first make use of the waste heat from the data centre planned for phase 2, then very low-energy geothermal energy, with air-source back-up as a last resort. The renewable energy share of such an installation is generally above 60% .”
