Headed by Donal McGowan, he says simple changes to lighting and heating have improved the university library's energy rating.

A 25,000sqm building, in 2003 it used 5.6 million units of energy, made up of electricity and heat.

Last year it dropped to 3.8 million units.

"The lighting comes on in the morning in time for the cleaners and automatically switches off at night. It also goes off when the library is closed.

"On the top floor there's a certain amount of natural light that comes in, so if it's bright enough outside, the lights automatically switch off.

"On the heating side, we increased the efficiency of the plant. We put in speed controls on those so we weren't moving more air than was needed.

"The system checks the quality of the air and ventilates if required."
