A new report shows that take-up of office space by public sector bodies has risen by over 1,000% since 2012.
The report, from Savills Ireland, said this reflects significant jobs growth in the sector, particularly since 2015, when the recruitment embargo was lifted.
4,900 new public administration and defence jobs were created in Dublin in the last year, enough to occupy 50,000 sqm of office space.
Savills noted that there were several large office lettings to the public sector in the first quarter of this year.
Tailte Éireann - the name of the Government body to be formed by the merger of the Property Registration Authority, Ordnance Survey Ireland and the Valuation Office - pre-let 16,722 sqm of space at The Distillers Building in Smithfield.
And the Central Bank has agreed to buy Blocks 4 and 5 at Dublin Landings, which is currently under development by Ballymore.
Dr John McCartney, Director of Research at Savills Ireland and author of today's report, said the impact of the public sector on Dublin's office market has gone relatively unnoticed, with some spectacularly large deals in the ICT sector overshadowing its significance.
Andrew Cunningham, Director and Head of Offices at Savills Ireland said jobs growth has contributed to increased public sector take-up.
But he said the increased takeup also reflected the Government's proactive approach to modernising and improving the quality of its business space portfolio to promote productivity and environmental objectives.
"Recent examples of this include moves by the Department of Health from Hawkins House - which was built in 1965 - to the newly refurbished Miesian Plaza, and the NTMA from the Treasury Building to No. 1 Dublin Landings," Mr Cunningham added.
