Display Energy Certificates (DECs)
The Advisory Report (AR) accompanies the DEC and contains recommendations for improving the energy performance of the building. Advisory Reports are valid for seven years.
The AR may contain a range of possible improvements, including cost-effective measures that may be implemented to improve the energy performance of the property. The report includes zero and low-cost operational and management improvements, possible upgrades to the building fabric or services and opportunities for the installation of Low and Zero (LZC) technologies.
The AR categorises the list of recommendations by payback period as follows:
Short term payback (up to three years), for example building energy management measures
Medium term payback (three to seven years), for example upgrading building services
Long term payback (more than seven years), for example LZC technologies
The advise provided in the AR is intended to be for information purposes only. Occupiers are advised to seek further detailed professional advice before reaching any decision on how to improve the energy performance of the building.
