Trinity College Dublin's new €80m Business School was opened today by Taoiseach Leo Varadkar.

The new building will house the scaled up Trinity Business School, a global leader in innovative business education programmes.

As the fastest growing established business school in Europe Trinity has joined the top 2% of accredited peers in the world according to EQUIS, the business school accreditation body.

The new building has enabled Trinity's expansion of curriculum, faculty and research across international business, finance, management and entrepreneurship.

The six-storey building on the city-centre campus includes an Innovation and Entrepreneurial hub, a 600 seat auditorium, "smart" classrooms with the latest digital technology and an executive education centre. 

Fronting onto Pearse Street and the University campus, the near zero energy building also provides another link between the city and the University.

The new building was financed with an European Investment Bank loan to Trinity College of €70m as well as philanthropic donations by business leaders and companies.

The EIB loan will be repaid over 30 years through income generated by the business school. 

The Dean of the Trinity Business School, Professor Andrew Burke said the opening of the new building marks the achievement of a mission to grow Trinity Business School from a niche player into a top international business school.

He said this involved the implementation of a high growth strategy that propelled the school to become the fastest growing established business school in Europe over the last three years.

"We now have a world class building for a world class business school located at the heart of our European capital city and hub for global business - that will be of major benefit for Ireland," the Dean added.

Speaking at the Trinity Business School today, Central Bank Governor said that high-quality business education and training at all levels - undergraduate, postgraduate, executive education - is a significant determinant of living standards and economic performance. 

Professor Philip Lane said that business education is especially pivotal in countries that specialise in the provision of business services on an international scale, which he said broadly describes the Irish economy.

He added he was convinced that the academia - both business schools and, more widely, the university sector - has a pivotal role in determining economic and social outcome through its educational and research activities. 

Also speaking at the new building today, the Director General of the Confederation of British Industry warned a hard Brexit would put the future vision of an all-island economy in peril.

Carolyn Fairbairn said a no-deal would represent a historic lost opportunity to raise living standards and spread prosperity across the island of Ireland.

She said an all-Island Irish economy would require a Brexit agreement that enables an open border and frictionless trade and a sudden exit from the EU would put this future vision at risk.

She added that this should not be allowed to happen.
