The Challenge

As a public sector body, daa is under obligation to reduce its energy usage by 30% by 2020. At Dublin Airport, a considerable amount of energy is required to power a reservoir to supply the facility's water demands. Each year the reservoir delivers 500 million litres to the airport ━ the equivalent of 200 Olympic-sized swimming pools. 

The daa needed a solution that would assist them in reducing energy costs to meet their public sector obligation, and positioning them as an international energy exemplar.




The Solution

  • ESB Energy undertook a large-scale solar project at the Dublin Airport. A 110kW solar PV array comprised of 268 photovoltaic panels covering 650m2 was installed and activated within 2 months. 
  • The partnership has delivered numerous energy saving solutions to date, including three combined heat and power unites and placed an onsite energy engineer.

The Results

  • Dublin Airport succeeded in reducing its carbon footprint by 5,000 tonnes per annum, equivalent to a 10% Reduction in carbon emissions
  • Energy consumption across two terminals reduced by 42%
