What Is BER
A Building Energy Rating (BER) label is a standardised way to examine and represent the energy performance of a property. The building fabric and its heating supply are surveyed.
The results are entered in a computer programme that, with climate data, calculates standardised heating demand and performance (standardised because, as we all use energy very differently, standardised comfort conditions remove personal variations and give us consistant comparisons). The combined results of the Heating Demand and Supply produce the Energy Label, similar to the labels currently used on domestic appliances for example.
The Heating Demand is an evaluation of the property fabric, constructions details and insulation of walls, roof, floor and windows and how much air is allowed in to the property.
The Heating Supply is an evaluation of the heating equipment, its system and controls and the fuel used.
By examining both Heating Demand and Supply and availing of more energy efficient materials and technologies available in the marketplace, the overall Building Energy Rating can be improved considerably for both new builds and existing dwellings.
According to the Irish Auctioneers and Valuers Institute, Building Energy Ratings will have a positive impact on property prices and an “A” rated residential property
- Attracts a premium price (at least 5%) over and above a similar residential property with a lower rating
- Provides a more attractive proposition from a potential purchaser’s perspective
- Financially benefits the owner, both in property value and energy costs.
An “A” rated home, therefore, is expected to be much more sought after by prospective purchasers
