Limerick city and Trondheim in Norway are the two cities chosen to lead the new +CityxChange programme which is designed to show the rest of Europe how to dramatically reduce the carbon footprint of urban areas.
Five Georgian properties in Limerick city centre have been selected to become a test bed for data collection.
The four older buildings in the scheme will be retrofitted and will have new technologies installed including energy storage solutions, electric cars, heat pumps and PV roof panels.
A new tidal turbine, developed by Limerick company Gkinetic, will also be placed in the River Shannon nearby to harness the water power of the river to generate positive energy for the pilot building cluster.
