Dublin Airport is planning a major facelift for Terminal 1 under plans that have been lodged with Fingal County Council.
Under the plans, the core façade and the roof of the terminal are to be replaced with a new modern, energy efficient structure.
The building's existing concrete fins, which are near the end of their life and need to replaced, will make way for a combination of glass and solid panels to create a fresh look for T1 that will improve the overall visual appearance of the airport campus, Dublin Airport said.
The planned works to the façade follow a major upgrade to both the Departures and Arrivals areas of Terminal 1 in recent years. New floors and lighting were installed and both areas were reconfigured to introduce more natural light to the building.
The upgrade project has been part of the long-term plans for Dublin Airport for several years. But as yet, no specific date has been set for these upgrade works to take place.
Dublin Airport's Managing Director Vincent Harrison said that while passenger traffic had been hit by the impact of Covid-19, as custodians of Dublin Airport on behalf of the State, the Daa must always take a prudent long-term view in relation to managing the facility.
"As certain elements of T1 are approaching the end of their life, it makes sense to seek planning permission now for these works, which will be carried out over the coming years," Mr Harrison said.
More than 20 million passengers used Terminal 1 last year. Its busiest year was in 2008, before the opening of Terminal 2, when almost 23.5 million passengers passed through the building.
The planned changes to Terminal 1 will generate a significant improvement in its energy efficiency, as it will move the upgraded elements of building from their current BER rating of F to B3.
The terminal's planned new façade exceeds current energy guidelines by 25%.
As part of the planned works, the roof of Terminal 1 will be insulated to the highest standards, thus significantly reducing heat loss from the building.
"Sustainability is at the heart of how we operate at Dublin Airport and this project will have a hugely positive impact on the overall energy consumption levels for Terminal 1," Mr Harrison said.
