Half of new homes fail energy efficiency rules

More than half of new Irish homes fail to meet energy efficiency and carbon emissions regulations, according to new figures. The number of new homes meeting the rules has also declined dramatically since 2005, according to data released by the Sustainable Energy Authority of Ireland.

The figures show 50% of homes fail to meet energy performance rules, 40% fail to meet carbon emission standards, and 39% don't generate enough renewable energy to meet regulations.

The data, which contains a record of the energy performance of every new home given a building energy rating (BER) assessment, was obtained by the green building magazine Construct Ireland.

Of the 3,595 BER assessments carried out on houses built to the 2008 version of Part L of the building regulations, which deals with insulation and energy, 1,946 ā€” or 54% ā€” fail at least one of the three main standards.

This marked a dramatic increase from the 21% of homes built to the 2005 regulations that failed to meet its main requirements. Part L was updated again last far, but few homes have been built to this new version.

Environment minister Phil Hogan recently published a new draft Building Control Act following the high profile evacuation of the Priory Hall development in north Dublin due to fire safety defects. The new rules require the submission of "certificates of compliance" for the design and construction of buildings.

However in a lengthy submission former president of the Royal Institute of the Architects of Ireland Eoin O'Cofaigh heavily criticised the proposals. He said the regulations would "criminalise" architects for the failure of local authorities to inspect buildings, and for the failure of other contractors on site. Local authorities currently have a target to inspect just 12-15% of new buildings.

Mr O'Cofaigh, a former member for the Building Regulations Advisory Body, said the proposals were the "21st century equivalent of hanging children for stealing sheep."

Last year Construct Irelandrevealed that an unpublished survey of Irish housing built between 1997 and 2002 commissioned by the SEAI found that none of the houses examined complied fully with energy efficiency regulations. Over 90% of of homes with oil boilers failed to comply with rules on reducing the risk of fire spread and pollution from oil tanks, while over 40% failed to meet ventilation standards.

Infra red photography of housing conducted as part of the survey found that 19 out of 20 houses had gaps in insulation, in contravention of the regulations, that were not revealed by basic visual inspections. This suggest the number of homes failing to meet insulation standards today could be higher than the latest SEAI data indicates, as BER assessors typically assume on-paper specifications are correct if they can't access insulation.

SEAI is planning to release a public research tool to enable users to study the BER data it has collected. The next issue of Construct Ireland magazine will contain further analysis of the latest figures. The Department of Environment did not respond to a request for comment from The Sunday Times in time for print.
