This document summarizes a community-led energy efficiency retrofit project in Tipperary, Ireland. The project started in one community in 2011 and has since expanded to include 110 homes across 4 communities. Local volunteers established energy teams to improve homes' insulation and appliances, reducing energy usage by over 900,000 kWh annually. Funding came from participant payments and government grants, employing local contractors and improving the rural economy. Challenges remain in expanding participation and developing sustainable financing models that empower community ownership over the long term.
