When improving an older home’s energy rating, the Sustainable Energy Authority of Ireland (SEAI) advises aiming for a BER rating of B2.
According to the SEAI, a B2 rating is considered the benchmark for “excellent energy performance” and as well as saving money on bills, hitting the B2 mark will also make for a more comfortable home and reduce your carbon footprint.
