Households with better energy ratings consumed less gas and electricity per square metre, new figures from the Central Statistics Office (CSO) show.
The CSO figures show that A and B rated dwellings used 42 kilowatt hours (kWh) of electricity per square metre in 2021, compared with 79 kWh per square metre for D and for E, and 67 kWh per square metre for F and G rated dwellings.
The means electricity consumption last year for properties built in 2005-2021 was 48 kWh per square metre, which was around two-thirds of the figure for dwellings built in 2000-2004 of 75 kWh per square metre.
