A surrounding glass facade merges the old and new buildings of the General Secretariat of the European Parliament in Luxembourg into an enclosed unit without any height differences. Schneider was on board this project with an extraordinarily comprehensive package of services consisting of the facade construction, roofs, doors, access systems and photovoltaics.

BREEAM certification for the “Near Zero Energy” Ensemble. On the occasion of the ground-breaking ceremony for the new building and expansion of the European Parliament in 2013, one of the most ambitious construction projects in the history of the European Union commenced in Luxembourg-Kirchberg. Following the renovation work, the existing complex of eight buildings together with the new buildings will provide space for up to 3,000 employees over an area of 250,000 square metres. The overall energy concept is expected to save operating costs of in excess of 100 million euros within a period of 20 years. Among other things, motion detectors for the lighting, a photovoltaic system spanning more than 8,700 square metres, solar collectors for the hot water generation, heat recovery, geothermal energy for heating and cooling, and many other efficiency measures were planned.

Facade construction scores highly by virtue of its energy efficiency. Schneider’s concentrated expertise in the field of facades was required over a facade area of 79,000 square metres. This is because the building envelopes are of course also designed with maximum energy efficiency in mind employing double facades, thermal insulation composite systems and triple insulation glazing. The aspects of comfort and aesthetics are also not neglected by us. Thanks to the Double Skin, the facades are soundproofed, solar protection with light deflection and natural ventilation also assist greatly in ensuring the well-being of the building’s users. Coloured glazing in 20 different shades of red, orange, yellow, green and blue provide varied eye-catching highlights on the glass facade.
