DAA envisages that DAC will provide Ireland's premier economic, educational and research zone with an estimate that once completed, the airport city, will contribute some €1 billion per annum to the Irish economy.

Dublin Airport Authority is a fully commercial business, enjoying the full backing of its shareholder, the Irish Government, and has extensive global airport, retailing and business networks, through its own operations and those of its international retail subsidiary, Aer Rianta International.

Financing for the €4 billion project will come not from the €2 billion earmarked for Dublin's modernisation programme, but from a combination of debt financing, strategic partners and an investment consortia.

To oversee the construction of such an ambitious project, a DAA subsidary will be created and will work closely with international partners to ensure expertise, transparency and that the project is for the public benefit.

Mirroring this commitment, the Wintergarden building will nurture a community that demonstrates serious commitment to creating Cleantech solutions for economic and environmental problems, and that community will be networked into other international centres for Cleantech.

A 'shared services centre' will be established that administers the building, organises meetings/conferences/ exhibitions, encourages a productive coexistence of companies and researchers and promotes the building as the central nervous system of the Cleantech industry in Ireland.

An educational programme will be designed to support tenant operations and will cover a wide range of Cleantech disciplines with state-of-the-art video conferencing, e-learning support, seminars and certification.
