Dún Laoghaire-Rathdown (dlr) County Council has scooped the 'Energy in Buildings' Sustainable Energy Authority of Ireland (SEAI) 2024 Award this month for their Ballyogan Square project.

Developed by dlr Architects as a pioneering example of sustainable social housing, the development features 67 new two and three-bedroom terrace houses.

The design optimises building envelope performance with high airtightness, continuous insulation and solar gain. They are all designed to Passive House standard.

Triple-glazed windows and minimal thermal bridging complement the sustainable design and the homes all achieve an A1 building energy rating.

They include solar PV panels, heat pumps and mechanical ventilation with heat recovery, which results in low energy bills and enhanced indoor air quality. 

Andrée Dargan, County Architect and Energy Performance Officer for Dún Laoghaire-Rathdown County Council, said: "dlr recognises the concept of Passive House to deliver high quality, economic, comfortable and healthy future proofed buildings.

"We are proud of delivering another public exemplar in terms of high-performance and low energy and emissions homes and receiving this year’s SEAI 'Energy in Buildings' Award."

Frank Curran, Chief Executive, Dún Laoghaire-Rathdown County Council added: "The shift towards more sustainable construction is essential, given that 40% of carbon emissions globally are from the built environment.

"The environmental, economic and social sustainability of the buildings are considered in the designs of all dlr housing and civic buildings."
