Building Energy Rating

6 February 2009

From the 1st January 2009 a Building Energy Rating (BER) is required for the sale or letting of an existing building.  Protected structures, proposed protected structures, buildings protected under the national monuments acts, and buildings used as places of public worship are exempt from the requirements of these regulations.

A B.E.R. assessment is an assessment of the energy performance of a particular building.  It does not bring about any requirement for works to be carried out to an existing building.  However, even where a building is exempt from the need for a B.E.R. assessment, some owners may nonetheless wish to up-grade the energy efficiency of their property.

While this is welcome, interventions that may be appropriate to a building of modern construction methods and material could have unintended harmful consequences for historic and traditional buildings and the health of their occupants, by promoting condensation and subsequent mould growth.  Where surveyors and owners of historic buildings are considering changes to improve the efficiency of their properties they should consult first with Clare County Council’s Architectural Conservation Officer at (087) 2905122 or email

The Architectural Heritage Advisory Unit of the Department of the Environment, Heritage and Local Government intends to publish guidance soon on the subject of upgrading the thermal efficiency of all traditionally-built buildings.
