Built in the 1960s, then extended in the 1980s, the site at 34 rue des Gardinoux in Aubervilliers is now undergoing redevelopment. The buildings will be demolished and then rebuilt as a nine-storey office building on a basement level with parking, plant rooms and a gymnasium. Terrell is undertaking a multidisciplinary assignment comprising structure, facades and services.

The structure will be of reinforced concrete, on a plot that has already been developed and incorporates 3 buildings with a shared basement level. Above ground, the load-bearing facades will be supported at 2.70-metre centres.

The ground floor facade will comprise a steel curtain wall, and the main facades of the upper floors will be glazed. On the eastern facades, the guardrails will be executed as translucent facades.

Based on a high level of certification, the project favoured very low-consumption equipment. The project incorporates a presence-detection system for the lighting and a Sun Tracking system to activate the blinds in the event of significant solar gain, making it possible to reduce energy input. Sun Tracking also transmits data to capitalise on the light levels in the buildings.

The boiler equipment was positioned on the flat roof and blanked-off connections were put in place with a view to recovering heat emissions from the Datacentre.

The following environmental standards are achieved:
– HQE (2015 new building guidelines) EXCELLENT level, together with the Low Consumption Building Effinergie 2017 energy performance hallmark
– BREEAM (New Construction 2016) VERY GOOD certification
– WELL Core and Shell gold level certification
