At almost half a million square feet (44,000 m2), The Convention Centre is the largest single-use building constructed in Dublin in decades and the first major public access building since the foundation of the State. The brief was to provide a building with a 100 year life span. The building is the world’s first ‘Carbon Neutral’ conference venue and achieved BREEAM assessment of ‘Very Good’ which was largely helped by leading edge design in its mechanical installations. The design feature of the 57m high glazed drum contributes immensely to the building’s visual impact. The glazing of the drum comprises 265 glass panels, the majority of which are 5.2m x 1.5m curved and weigh 700kg each.
