Newer homes are more energy efficient

An extensive audit of the nation’s housing stock has shown recently built houses are far more energy efficient than older homes.

The Central Statistics Office has revealed almost half a million dwellings had a Building Energy Rating (BER) audit conducted between January 2009 and June 2014.

The survey of 488,199 units found that 92% of homes built since 2010 have a BER of B or higher, compared to houses constructed in 2005-2009 where only 1% received an A rating and 38% a B rating.
