BER B2 Rated Homes | 5,050 | 53% |
Energy-Poor Homes Upgraded | 1,200 | – |
Understanding Home Energy Efficiency Ratings in Ireland
In Ireland, the SEAI certifies home energy ratings through the Building Energy Rating (BER) system. This system rates homes from A1 to G5. It helps homeowners understand their home’s energy use and how to improve it. Using energy-efficient heating, like condensing boilers or heat pumps, can boost a home’s BER rating5.
Improving a home’s BER rating is crucial. Passive house retrofits help by reducing heat loss through walls, attics, and windows5. A home loses 20-30% of its heat through walls and up to 30% more through a poorly insulated attic5. By choosing energy-efficient heating and passive house retrofits, homeowners can cut energy use and increase their property’s value.
The cost of making a home more energy-efficient varies. It depends on the home’s age and size, with costs from €25,000 to €75,000 or more6. But, SEAI grants can help lower these costs6. By understanding the value of home energy ratings and investing in efficient heating and retrofits, homeowners can make their homes more sustainable and comfortable.
