History
Established as a School of Commerce in 1925, the School has grown from offering B.A. and BComm degrees to offering an MBA programme since 1964 when it was transformed into a School of Business Studies. A full suite of Masters programmes exist today and this began in 1976 when the MSc (Mgmt) degree in Management Practice for practicing senior executives was launched, with a curriculum based on action research principles. The School is part of the Faculty of Arts, Humanities and Social Sciences of Trinity College.

It is a near zero energy building, with some 500sq m of photovoltaic panels installed on the roof contribute to the electrical provision of the building and offsetting 35 tonnes of carbon per annum.
