Donegal County Council has recently completed a major renewable energy retrofit project to Letterkenny Public Services Centre. The Council has installed;

·         5no.  42.6 kW air-source heat pumps to replace our oil boilers

·         20no. photo-voltaic solar panels to generate 6 kW of electricity

·         pumped cavity bead insulation to 762m2 of external walls

·         new efficient heating controls and upgrades to the building management system

·         live smart monitoring equipment for the electrical generation and heat pumps consumption


Peadar Espey, Facilities Manager and Energy Performance Officer notes “the aim of this energy retrofit project was to make a significant practical energy upgrade, removing the dependency on fossil fuel as a space heating source. This project aligns Donegal County Council’s energy policy with the policies of our national Climate Action Plan 2021 and builds on last year’s energy retrofit works at Milford Public Service Centre”.


This project delivers on the excellent work Donegal County Council has achieved at these public offices over the last four years. A list of completed energy efficient and sustainable biodiversity projects are listed below. 

·         2018: Project - full internal and external LED lighting upgrades

·         2019: Project - 4no. electric vehicle charging points

·         2020: Project - sedum roof regeneration through pollination. 35,000 native Irish honeybees

·         2021: Project - Letterkenny Public Services Centre - Major Renewable Energy Retrofit



International Standard

Donegal County Council was recently certified to the International Standard for Energy Management – ISO 50001:2018 and continues to deliver improvements in energy use, carbon emissions and cost using this framework. This helps the authority to deliver on its own internal energy saving targets as well as the national public sector targets of 50% energy efficiency improvement by 2030 (Baseline 2009) and 51% reduction in absolute tonnage GHG (CO2eq) by 2030 (Baseline 2016-2018) under the Climate Action Plan 2021.


Peadar Espey, Facilities Manager and Energy Performance Officer notes “the project has eliminated approx. 54 tonne of carbon per annum with the removal of our oil boilers and generates approx. 5,000kWh per annum through the installed photo-voltaic solar array.
