The project is the first educational building of its size to use bio-fuel.
Sir Reg's Department for Employment and Learning funded the scheme through the Reinvestment and Reform Initiative, which was set up by the Executive in 2002.
The new building provides teaching accommodation for the University and will also house the Art, Health and Leisure, Physical Education and Technology and Design subject areas.
Speaking at the opening Sir Reg said: "I must commend all involved in the design and construction of this tremendous learning facility for their attention to environment and sustainability issues which have been considered in detail at every stage of this development."

"As the first building of this scale within the education sector to use bio-fuel, the Orchard Building is an exemplar and a beacon of best practice."
"Indeed, this approach to environmental and sustainability issues entirely complements the Assembly's Programme for Government target to create a sustainable and fit for purpose higher education estate."
"Stranmillis University College has a long established reputation for excellence and I know that the Orchard Building will greatly enhance the learning and teaching experience of staff and students for many years to come," added the minister.
Sir Reg also congratulated the design team Scott Wilson, who lifted an industry award earlier this year for their work.
