  • The building is fully air conditioned using active chilled beams for the lettable office spaces and four pipe fan coil units for the central core areas
  • A comprehensive Building Energy Management System provides centrally managed control of all mechanical and electrical systems with full monitoring ,recording and alarm indication of all system all networked to the DAA’s site wide management/control system

Electrical services include:

  • A full complement of electrical systems commensurate with Grade A office accommodation including
  • HV installation
  • Sub-station/switchgear
  • Power distribution
  • Data/communications network
  • Security and control systems
  • All lighting systems are based on high efficiency LED luminaires with the lighting systems very closely integrated into the overall architectural/interior design of the building

The mechanical and electrical systems have been designed and equipment selected to optimise energy use which provide a major contribution to the building achieving a LEED “GOLD” rating. To assist with obtaining this level of accreditation a full dynamic thermal model for the building was developed and the outputs from this were used to inform the selection of building fabric and services infrastructure.

The Design & Build Redevelopment by Walls Construction of One Central, the former Aer Lingus head office at the airport, commenced in March 2015 and was scheduled for completion in February 2016. The six-storey over basement building, with a floor area of 8,300sqm, is to Grade A specification, LEED Gold Certification and A3 BER. The façade is now complete and provides an impressive and eye catching vista on the airport campus. Hard landscaping and soft landscaping have commenced which will add the final touch for the imminent unveiling of this project by the DAA.
