The double-skinned facade on the impressive No 1 Bligh Street building in Sydney, NSW incorporates external louvres for natural ventilation.

Designed by Architectus in association with Ingenhoven Architects (Germany), the building has achieved 6 Star Green Star Office Design v2 and Office As-Built v2 Certified ratings from the Green Building Council of Australia as well as a 5 Star NABERS Energy Rating.

EBSA's partners Schneider Louvres worked with G.James Glass and Aluminium on the project, taking an innovative approach to integrate the louvre mechanisms into the curtain wall frames. This resulted in a facade without secondary louvre framing; the EBSA G12 BS (BS = Bligh St) louvre system was born from the hardware developed for this project.

EBSA Pty Ltd is very proud of their association with the No 1 Bligh Street project, and continues to provide ongoing service and maintenance to all the louvres including the ground floor lobby louvres, the Jalousie louvres on level 30 and the Schneider G12 BS louvres that span the full height of the internal atrium from level 1 to level 29. These louvres are also connected to the BMS and fire system via EBSA’s D+H Mechatronic smoke control panels.
