Building Energy Ratings (BERs) are now requires for all neew buildings that applied under the European Communities (Energy Performance of Buildings) Regulations 2006 (S.I. No. 666 of 2006). It is the responsibility of all building owners to produce a BER for inspection by prospective purchasers or tenents.
How to get a BER:
Only registered BER assessors can carry out an official BER assessment and it must be submitted to SEI for publication on the national register of BER assessments. Green Man Energy are SEI registered BER assessors.
BER Methodology for dwellings:
The official method for carrying out a BER for a dwelling is the Dwelling Energy Assessment Procedure (DEAP3). It consists of step by step calculations within a series of individual modules.
These modules deal with:
The calculations emerging from these modules are combined to produce an overall calculation of annual energy demand and CO2 emmissions. The dwelling is then given a rating on a scale of A1 (best) to G (worst). A detailed account of the standard BER procedure for Ireland is set out under the heading 'DEAP' in the SEI website (www.sei.ie). Under the DEAP methodology, a new dwelling which meets the 2007 building regulations is expected to use 40% less energy than the "Standard Dwelling" and employ a source of renewable energy.
Expected rating for a typical 3 bed semi is B1.
In order to achieve this rating, developers will be required to design dwellings to include energy efficient features such as condensing boilers, passive solar design, energy efficient glazing, increased insulation levels, renewable energy technologies, etc..
The DEAP methodology is based on standard occupancy assumptions and a range of technical judgements regarding the energy efficiency impact of various building components and attributes. In practice the energy efficiency of a building will depend on how the occupants operate the building. The BER for a dwelling may change over time due to many factors including deterioration or modification to the fabric of the building, changes to the heating syatems incorporating into the building or changes in the way in which buildings are rated.
BERs are required in the following circumstances:
A person offering a new dwelling for sale or letting (whether in writing or otherwise) is required to produce a copy of the BER to the building control authority for the area on demand and to any person expressing an interest in purchasing or renting the relevant building.
New Non-Residential Buildings
A person who offers a new building other than a dwelling, for sale or letting will be required to produce a copy of the BER to the building control authority on demand and to any person expressing an interest in purchasing or renting the relevant building if planning permission was applied for on or after 1st July 2008. Transitional BER exemptions will apply to new non-domestic building for which planning permission is applied for on or before 30th June 2008 provided the new non-domestic buildings involved are substabtially completed by 30th June 2010.
Existing Buildings (Dwellings and Non-Residential Buildings)
A person or their agent who offers a new or existing building for sale or letting on or after 1st January 2009 is required to produce a copy of the BER to the building control authority on demand and to any person expressing an interest in purchasing or renting the relevant building.
Therefore all buildings offered for sale, lease or rent now require a BER certificate as well as new build owner occupied buildings.
Full details of exempt buildings can be found on the SEI website (www.sei.ie) and include the following:
The European Communities (Energy Performance of Buildings) Regulations 2006 (S.I. No. 666 of 2006), provide that certain actions in respect of BERs are offences punishable by a fine not exceeding €5000:
"Failure by the owner of a building or the agent of such owner to produce and allow inspection by a building control authority or an authorised officer therof of within 28 days a printed copy of a BER certificate required in respect of that building by the regulations."
"Making a statement for the performance of his or her functions to a BER assessor, to SEI, or to an authorised officer that he or she knows to be false or misleading in a material particular or recklessy making a statement that is false or misleading in a material particular."
"Failing to disclose a material particular to a BER assessor, to SEI, or to an authorised officer for the performance of their functions."
