Explaining Display Energy Certificates

Display Energy Certificates (DECs) provide buildings with an operational rating, in terms of energy usage, on a scale of A-G (A being the most efficient). DECs are based on the actual amount of metered energy used by the building over a 12-month period. A DEC and Advisory Report (AR) are required for public buildings with a useable floor area over 500m2 that are occupied in whole, or in part, by public authorities and by institutions providing public services to a large number of persons, and are therefore frequently visited by members of the public.

Software from SystemsLink

Through our partnership with SystemsLink you can access OR Toolkit software. Full training is given in the use of the software to process DEC data and lodge the advisory report.

Continuing Professional Development

We recommend the completion of a minimum of 10 CPD hours to maintain your DEC certification. Stroma Certification provides regular CPD sessions to members to assist with fulfilling this requirement.
