Project Description

Dublin City University is situated on an 85 acre campus near the city centre.  It was initially set up to fulfill the national requirement for a highly-trained workforce with skills in the areas of business, science and electronics, computer technology, communications and languages and as an agent for change in its local community. The first students came through the door in 1980 and the university is now recognised nationally and internationally as a centre of academic excellence.  It was awarded university status in 1989.

In 1990, a new Business School building was constructed as part of the overall Dublin Business School campus in Glasnevin Dublin.  It is a 3-storey building with 4 no. plant rooms at roof level.  It consists of 2 no. 200-seater lecture halls, 12 no. 100-seater and 8 no. 50-seater lecture halls with a number of tutorial rooms and general offices. In 1996, a 3-storey extension to the Computer School was built consisting of a number classrooms, tutorial rooms and offices.  In 2007, a 3rd Executive Floor was added to the Dublin Business School 1990 building consisting of 1,600m2 of floor space broken down into 7 no. lecture theatres, boardroom, open areas and offices.

The mechanical installation consisted of a number of air handling units located in 3 no. plant rooms at roof level feeding the various lecture theatres.  The tutorial rooms and offices were heated via a low pressure hot water radiator system fed from a central boiler house located at roof level.  The electrical installation consisted of general lighting, general power, telephone and data network installation.  There was also a fire alarm system, intruder alarm and CCTV systems associated with this building.

The gas fired boiler plant is fed from the natural gas network on the site.  The electrical supply to the new main electrical switchboard in the school is running back to the existing electrical centre that serves the campus.  The telephone and IT systems are networked back to the main hubs on the site. 

In 2006, due to the increase in numbers attending the Business School and the demand for additional administrative space, Dublin City University put forward a plan to provide a 3rd Floor onto the original 1990 Building.  The brief was to maintain all the operations of the existing building and have the project completed prior to the start of the autumn academic year.  Within this brief, the 4 no. existing rooftop plantrooms were required to be maintained and accessible during the construction period.

The existing lift was decommissioned and the shaft was extended and provided with a new lift to cater for all floors.  The new lecture rooms were fitted out with audio visual systems (AV).  The cable management system for the AV was utilised through the raised floors and ceiling voids.  Each AV system was integrated with the IT network to allow conferencing with any other university located around the world.  Again, the telephone, IT and security networks were linked back to the communications rooms hubs around the site.  The design of the services had to provide an element of sustainability and this was achieved by the following:


  • Modulating condensing gas boilers
  • Variable speed heating circulating pumps
  • Low water content heating emitters
  • Lighting management systems
  • Movement/absence lighting detection systems
  • High frequency modular light fittings
  • Air handling plant with mixing / re-circulating chambers

The existing building energy management system was extended to cater for the new floor.  The BMS software was updated at the central management centre located in the Estates Office to integrate with the new plant and services.  In addition, the system has been maintained since completion with a view to adjusting set points to reduce energy costs.

The mechanical services for this building consisted of cassette units above the ceilings in the lecture rooms providing comfort cooling with the condensers located at roof level.  Also, there are air handling units at roof level providing temperate fresh air to the building.  The heating to the tutorial rooms and offices is provided by radiators fed from the central boiler at roof level.  The electrical installation consists of general lighting, general power and data network installation.  There is also a fire alarm system, intruder alarm and CCTV systems associated with this building.
