As much as €2bn will be invested in Dublin's IFSC between now and 2021, it has been claimed.
The claim came as Dublin City Council (DCC), the Sustainability Energy Authority of Ireland (SEAI) and the International Sustainability Investment Centre (formerly the Green IFSC) launched a new initiative called Docklands 21.
The move is aimed at improving energy efficiency in Ireland's economy by as much as a fifth.
According to the organisers, there will be an estimated €2bn investment in office space and 2,600 residential units in the capital's docklands area over the next six years.
That figure is thought to include a number of planned developments, but final costs have yet to be finalised in a number of cases.
"This Government is firmly committed to the ambitious goal of improving the energy efficiency of Ireland's economy by at least 20pc by 2020," Minister for Communications, Energy and Natural Resources Alex White (inset) said.
"This is a challenging target but reaching it will lead to a sustained long-term increase in incomes, employment and economic activity and improve competitiveness of our economy.
"Flagship projects like Docklands 2021 will play an important role in meeting this target, not only for the energy savings they deliver but also convincing more firms and communities across Ireland to work together and develop similar collaborative projects that can demonstrate the wider benefits of energy efficiency."
