Construction is underway on a 15 million euro upgrade of the Shannon Airport terminal building.
It marks the Shannon Airport Group’s first airport-focussed element of it’s 40 million euro investment drive for 2026.
This phase marks the beginning of the latest programme of works across Shannon Airport, aimed at enhancing passenger facilities and delivering long-term sustainability improvements.
As part of the works, the 1970s section of Shannon Airport’s main terminal building will be replaced with a modern, curved architectural façade, designed to dramatically improve energy performance.
This aims to facilitate the terminal’s transition to electric heat pump technology and new HVAC (Heating, Ventilation and Air Conditioning) systems, enabling a move away from fossil fuel systems and significantly reducing greenhouse gas emissions.
Upgraded toilets, improved lighting and flooring, clearer signage and new layouts will also be delivered in the immigration and baggage halls, with a view to reducing queues and streamlining passenger movement.
The old 1950s link corridor will also be removed, in an effort to save approximately 62 tonnes of CO2 annually, by eliminating the requirement to heat and cool the old structure.
New accommodations for Fixed Based Operators will also be constructed within the Arrivals area of the terminal building.
Galway-based OCC Construction has been appointed to carry out the works, which are now underway, with project completion expected in May 2027.
Additional projects included in The Shannon Airport Group’s 40 million euro investment programme for 2026 include upgrading taxiways and the completion of Blocks Y & Z, two state-of-the-art industrial units at the Shannon Airport Business Park.
In a statement to Clare FM, Interim CEO of The Shannon Airport Group, Ray O’Driscoll said: “The commencement of this €15 million arrivals area upgrade marks a significant step forward in our commitment to lowering emissions, improving energy performance and enhancing the customer experience at Shannon Airport.
“As part of our overall €40 million investment programme, this project will enable major carbon reductions while also modernising one of the most important parts of the terminal.
“This work builds on the numerous enhancements we’ve already delivered and is a further investment in our passengers and in a sustainable future.”
