Building Energy Ratings (BERs) are now required for all new 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 tenants.
How to get a BER:
Only Registered BER Assessors can carry out an official BER assessment and it must be submitted to SEI f
or publication on the national Register of BER Assessments. Gilroy Energy Services 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 (DEAP 3). It consists of step by step calculations within a series of individual modules.
The modules deal with
- Building Elements
- Heat losses
- Domestic hot water
- Internal heat gains
- Solar heat gains
- Mean internal temperature
- Space heat use
- Space heating requirements
- Total energy use and fuel costs
- Energy emissions
The calculations emerging from these modules are combined to produce an overall calculation of annual energy de
mand and CO2 emissions. 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 web site (www.sei.ie).
Under the DEAP methodology, a new dwelling which meets the minimum standards as set out in the Building Regulations is likely to score the following ratings:
In order to achieve higher ratings developers will be required to design dwellings which go above the minimum standards and which 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 systems incorporating into the building or changes to the way in which buildings are rated.
BERs are required in the following circumstances:
- New Dwellings
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 if planning permission was applied on or after 1st January 2007. Transitional BER exemptions will apply to new dwellings for which planning permission is applied on or before
31st December 2006, provided the new dwellings involved are substantially completed on or before 30th June 2008.
- 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 buildings for which planning permission is applied on or before 30th June 2008 provided the new non-domestic buildings involved are substantially 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 t
he 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 and include the following:
- a new dwelling for which planning permission was applied for or a planning notice was published on or before 31st December 2006 and is substantially completed on or before 30th June 2008
- a new building other than a dwelling, for which planning permission is applied for or a planning notice was published on or before 30th June 2008 and is substantially completed on or before 30th June 2010 except where suc
h a building is being offered for a second or subsequent letting
- National monuments
- Protected structures
- Buildings used as places of worship
- Temporary Buildings
- Non Residential Agricultural buildings with an installed heat capacity that does not exceed 10W/m2
- Industrial buildings with an installed heat capacity that does not exceed 10W/m2
- Stand alone buildings with a total floor area of less than 50m2
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 fines and imprisonment. For example, the following offences are punishable by a fine not exceeding €5,000:
- “Failure by the owner of a building or the agent of such owner to produce and allow inspection by a b
uilding control authority or an authorised officer thereof 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 recklessly 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”
BER Scheme Marketing Guideines For Developers:
Marketing Guidelines are now available with respect to inclusion of references to SEI or Building Energy Rating in promotional materials for Housing Developers. Developers should consult SEI before using any material or reference to BER or SEI.<
