Public Building Assessor for Display Energy Certificates (DEC) Certification Scheme

Public Building Assessor for 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 1,000m2 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.

Only qualified DEC Assessors can carry out public building assessments, i.e. producing and lodging Display Energy Certificates (DECs) and Advisory Reports (ARs). To become a DEC assessor you can undertake Stroma Certification’s training and sit the examination, which is ABBE approved.

Being qualified to join the certification scheme proves you are able to carry out work competently and to a high standard. To qualify, candidates need to:

  • Provide a copy of the exam certificate for proof of qualification.
  • Provide details of your insurance for Professional Indemnity and Public Liability.
  • Complete a minimum of 10 CPD hours. .

Stroma Certification also conducts regular audits from a sample selection of DECs to ensure consistency.
