The goal of the District Heating and Cooling (DHC) TCP is to advance the understanding of the technical, economic and social benefits of district energy through applied research and outreach.

Executive Committee

Underground insulated district heating and cooling pipes

District heating and cooling is recognised as a key component of Ireland's energy efficiency and climate change mitigation strategy. Its deployment will support the reduction of greenhouse gas emissions and the decarbonisation of our energy supply.

The IEA TCP on District Heating and Cooling aims to enhance the design, performance and operation of distribution systems and consumer installations. This international research effort will enable cost-effective and flexible large-scale integration of low-carbon energy sources into the heating energy mix.

The DHC TCP Executive Committee Representatives for Ireland are Mr. Peter Kehoe (SEAI) and Dr. Niamh O'Sullivan (SEAI).
