Keeping an eye on Energy efficiency, aesthetics, and protection of a listed building

Until recently, the auditorium of Belgium’s leading opera house was lit with 1,500 halogen lamps, each consuming 40 W. Replacing these energy collectors with energy-efficient LED lighting was one part of an all-in project entrusted to ENGIE Fabricom. During a renovation over 2 years, the entire lighting of the stage and the side wings was renewed and fitted with LEDs. The opera house reopened its doors in the autumn of 2017, bathed in completely new lighting.

ENGIE Fabricom’s role

ENGIE Fabricom’s technical expertise was of crucial importance, because the old cables had to be reused for the new electrical and lighting installations as much as possible. It has to be remembered that Muntschouwburg opera house is a listed building, so simply drilling holes for conduits is not permitted. ENGIE Fabricom was responsible for:

  • Renewing the electrical installation in the concert hall, including fitting LEDs to the majestic chandelier.
  • State-of-the-art stage lighting.
  • Emergency lighting and normal lighting in the access areas and staircases, which has to remain on during performances.
  • In the wings, the challenge was to install lighting which was out of view to the public, but could nevertheless provide enough light for actors and technicians to walk around safely during performances. We decided to use a system of small lights that are white during rehearsals and blue during performances.
