At the heart of the University of Malta Valletta Campus is the Aula Magna which, for decades, has been used as one of the main meeting and conference spaces in Valletta. The Hall has just undergone a major refurbishment project where all the plant and equipment has been changed while respecting the historic fabric of the building. The air conditioning and ventilation systems have been integrated through the use of the rooftop packaged units equipped with direct free cooling. These systems decrease energy consumption especially when the ambient conditions are such, that climate control can be accomplished simply by modulating the amount of fresh air delivered to the space. A DMX lighting control system has also been installed, making the Aula Magna very versatile with respect to the functions it can cater for, from exhibitions to product launches to conferences and lectures
