Terminal 2 formed the centrepiece of a five year transformation programme at Dublin Airport to upgrade and modernise facilities, increasing capacity and enhancing passenger experience.
Capable of comfortably processing up to 15 million passengers per year, Terminal 2 allows the airport to handle up to 32 million passengers annually, supporting the future growth of Dublin Airport from its current position as the 13th largest in Europe for international traffic.
A user-friendly design
The brief required that the building be adaptable to the changing needs of the airport and provide a user-friendly and enjoyable experience.
The team, made up of Arup, Pascall+Watson and Mace, was chosen to plan and design the Terminal 2 project after a rigorous selection process by the DAA. Davis Langdon was appointed as cost consultant for the design team. The team drew on the international aviation planning and design experience, taking account of emerging trends in passenger processing, in the application of technology, in airport retail and in sustainable design.
Prominent amongst the DAA’s objectives was the requirement to produce a design for the new terminal as both a landmark building and a gateway into Ireland for the 21st century.
By incorporating a full US pre-clearance facility, only the second (alongside Shannon) outside North America and the Caribbean, T2 improves convenience for US-bound travellers, who are treated as domestic passengers on their arrival.
5,000m2 terminal building
9,000m2of retail outlets
A fully equipped terminal
The project included a 75,000m2 terminal building, incorporating passenger and baggage processing, security screening and over 9,000m2 of retail outlets.
The terminal also has a new pier, serving a total of 19 aircraft parking stands, upgrades to the access road network, providing separate approach roads for the new and existing terminals and a new energy centre with combined heat and power.
Sustainability considerations were also an integral part of the design process.
Daylight and electric lighting
The lighting scheme contributed to an overall 17% reduction of CO2 (compared to a code compliant design). Daylight and electric lighting were manipulated to facilitate way-finding and enhance the passenger flow through the terminal. The lighting scheme is functional yet qualitative and is designed to complement the architecture of the building by accentuating its linear form, whilst providing a sense of calm and clarity for passengers and visitors.
The design brief was to provide a building lit to the best international standards for both staff and passengers whilst minimising energy consumption and reducing maintenance costs.
Lighting was used to reinforce the sense of direction through the building and guide passengers through the airport. Daylight enters from the glazed façades and roof skylights along the spine of the building. Solar shading was designed to minimise heat gains yet permit sunlight penetration in selective areas, so as not to cause discomfort to passengers.
Energy efficient light sources were used to lower energy consumption, and increase lamp replacement intervals and servicing; resulting in reduced maintenance costs. A Dali protocol was used to link daylight and electric lighting, resulting in minimal energy wastage, and luminaires were designed to be dimmed or switched to suit operational conditions.
The design incorporated energy reduction and consumption requirements with the lighting scheme contributing to an overall 17% reduction of CO2.
