Building Energy Rating (BER)
What is Building Energy Rating ("BER") Certificate?
A BER Certificate is an energy rating for a building. A Building Energy Rating is determined based on the measurement of the kWh/m2/yr. This is derived from a complex calculation based on the measurement of the U-values of each of the relevant components of the building.
A U-Value is the measure of the rate of heat loss though a material. Therefore when designing a home it is very important to consider the U-value of each component of the building and to choose the lowest possible U-value, where it is cost efficient to do so.
Which buildings need a BER Certificate?
New dwellings: The regulations apply to new dwellings for which planning permission was applied for on or after 1st January 2007.
New Non-Domestic Buildings: The regulations apply to new non-domestic buildings for which planning permission was applied for on or after 1st July 2008.
Existing Buildings (dwellings and other buildings) when offered for sale or letting on or after 1st January 2009.
A BER Certificate remains valid for 10 years
A Provisional BER Certificate remains valid for 2 years.
An Advisory Report that contains recommendations to improve the energy rating will also be issued with each BER certificate.
“Advisory Report” means a report held, and which may be viewed, in electronic form on the BER register, to accompany a BER certificate or Provisional BER Certificate, on the basis of a BER assessment of a building and in a form approved by the issuing authority with the prior approval of the Minister, which contains recommendations on how the energy performance of the building may be improved in a cost-effective manner.
A Provisional BER cert can be completed when using initial construction drawings (before dwelling is constructed). This Provisional Cert is only valid for a maximum of 2 years while the dwelling is being constructed. If the dwelling has not been completed within this period, a further provisional cert will be required. A Provisional Cert should also include any improvements that can be made to improve the BER.
A complete BER cert can only be completed when the dwelling has been completed to the specification given with the initial drawings. If any changes or improvements have been made, this must be included in a new specification sheet and the builder / client must sign the declaration of conformance that the dwelling has been built in accordance with the Building Regulations or a new specification sheet if better quality materials were used.
