Today all public buildings with a gross internal floor area greater than 1000m2 are required to display a Display Energy Certificate (DEC) in a prominent place clearly visible to the public. This requirement is a consequence of the transposition into Irish legislation of Article 7(3) of the Energy Performance in Buildings Directive.
The DEC for large public buildings is calculated as an operational rating, where the actual energy consumed in the building is compared to a benchmark for buildings of the same type, and shown on the certificate A-G scale in terms of primary energy. There is also a CO2 indicator which shows the CO2 emissions associated with the building's energy consumption.
The information required to carry out the rating consists of the gross internal floor area of the building and records of the total energy used in the building (eg electricity bill, gas bills, meters etc) over the past 12 month period.
In conjunction Energy Experts Ireland an annual fee can be agreed to cover all registering and updating of any required Display Energy Certificates (DEC) that you may require
