A BER (Building Energy Rating) is standard calculation of the energy performance of a building, produced by a qualified assessor using procedures including calculation method and software approved by SEI and including a survey of the building where required by direction of SEI. BER is based on primary energy demand and the BER scale ranges from “A1” (most efficient) to “G” (least efficient) in terms of primary energy demand.
Building Energy Rating (BER) is a requirement of the EU Directive on the Energy Performance of Buildings (2002/91/EC of 16 December 2002), which has now been transposed in Ireland by the European Communities (Energy Performance of Buildings) Regulations 2006 (S.I. No. 666 of 2006)
The building owner is required to provide the BER to prospective buyers and tenants. BER will, therefore, make the energy performance characteristics of the building transparent to prospective buyers and tenants. As a result, buyers and tenants will be able, for the first time, to take energy performance into consideration in their decision to purchase or rent a building. A BER certificate must be procured by the person commissioning a dwelling for their own use, prior to taking up occupation of the dwelling.
The requirement to provide a BER is being introduced on a phased basis as follows:
New dwellings: The regulations apply to new dwellings for which planning permission was applied for 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, where the new dwellings involved are substantially completed on or before 30th June 2008.
Existing Buildings (dwellings and other buildings) when offered for sale or letting on or after 1st January 2009.
The following building categories are exempt from BER, as permitted by the EPBD:
Places of worship or buildings used for the religious activities of any religion;
Certain temporary buildings;
Non-residential industrial or agricultural buildings with a low installed heating capacity
(less than 10 W/m2);
We offer air tightness testing for residential dwellings. The revised building regulations (24th January 2008) introduce mandatory air pressure testing for new dwellings.*All new single dwellings will require an air pressure test from 1st July 2008. Guidelines have been set out in relation to developments. These guidelines are outlined below. The aim of air tightness testing is to measure the flow of air within a building and identify areas that are experiencing heat loss.
Air tightness measures the flow of air within a building. Air leakage is the uncontrolled flow of air through gaps and cracks in the fabric of a building. Improving air tightness in a dwelling can reduce air leakage. The aim of air tightness is to "build tight, ventilate right". This means that there are no breaks or gaps in the envelope of the building fabric and there is complete control over the ventilation system within the building. Having an airtight property does not mean there is insufficient air flow, it means there is controlled air flow. The only satisfactory way to measure air tightness is by using blower door test equipment.
Air tightness testing highlights areas of heat loss. These areas are increasing your energy consumption and, with it, the amount of money your property is wasting. Air tightness and thermal imaging can locate these areas and therefore allow you to make the necessary changes to increase the energy efficiency of your home.
