Retrofitting your home involves making improvements to increase energy efficiency and lower heating bills. Some effective retrofits include attic insulation, draft proofing, wall insulation, upgrading heating systems and controls, and installing more efficient windows. The Sustainable Energy Authority of Ireland offers grants for home energy upgrades that can improve a home's Building Energy Rating. Attending an upcoming event hosted by the local organization The Green Village is recommended to learn more about practical retrofitting options and get advice on getting started with a retrofit project.
