SSE Airtricity 

SSE Airtricity provides energy-related services to home and business customers. The Limerick 2021 Energy Efficiency Upgrade Project carried out significant energy upgrade work. It has already helped in the advancement of energy efficiency technologies. It focussed on 59 Local Authority homes with an average BER ‘D” rating enhancing them to a BER ‘A’ rating. This project was part of a government initiative. SSE partnered with Limerick City & County Council. Their goal was to upgrade properties which had been identified as most in need of energy efficiency upgrades. They implemented advanced insulation, heat pumps, solar panels, and batteries. They generated combined energy savings from this project to a 90% improvement. They reduced carbon emissions by 340 tonnes of CO2 per year. The Limerick 2021 Energy Efficiency Upgrade Project will have a lasting impact on the community. 



STUDIO NEGRI has been involved in residential deep retrofits since 2010. It promotes the use of natural materials and focuses on carbon reduction. It works on transforming old buildings to high energy performance. It does this by using renewable energy sources. Transforming old buildings, they have upgraded all building types in an innovative way. The focus is on projects that extend the future lifecycle of these properties. House types achieving BER ‘A’ ratings range from protected structures built in the 1830's, to a semi-detached house built in the 1970's. STUDIO NEGRI demonstrates that by using the approach of reduce, reuse, recycle and retrofit, old structures can be transitioned into Nearly Zero Energy Buildings.
