Energy Assessors wishing to produce Display Energy Certificates (DECs) and Advisory Reports (ARs) for large public buildings will need to gain this qualification. This will allow them to be accredited as Display Energy Certificate Assessors (DECAs).

This applies to buildings with total floor area greater than 1000sqm, occupied by public authorities or by institutions providing a service to the public, and visited by large numbers of the public. These need to display a current DEC (no more than a year old) and to have available an AR that is no more than seven years old.

DECs and ARs are produced using an Operational Rating (OR) based on energy usage in the preceding year. The course includes full training in the OR methodology and in the use of the government-approved ORCalc software to produce the DEC and AR. It also includes the opportunity to assess a real building under the guidance of ecmk's trainers.

Candidates must also assemble a Portfolio of Evidence of their competence in the role, including DECs for three real buildings. Each candidate is assigned to a Qualification Assessor to guide them through this process. The Qualification Assessor finally assesses the Portfolio to verify that the candidate meets the minimum requirements of the National Occupational Standards for a DECA.

Finally, all candidates must pass a short exam set and marked by ABBE (The Awarding Body foir the Built Environment).

Course format
  • One day induction covering the legislative background, an introduction to the OR methodology and details of how to assemble the Portfolio of Evidence.
  • Two days training on building construction and services, to enable Assessors to recognise the construction types and building services found in commercial buildings.
  • One day ORCalc software training including the conventions of data collection and entry.
  • One day practical, including an assessment on a real commercial building under guidance from ecmk's trainers.
  • Three to six weeks working remotely with the guidance of a Qualification Assessor to assemble the Portfolio of Evidence.
  • Two days assessment, including final assessment of the Portfolios.
  • The ABBE external examination.

There are no pre-qualifications to attend this course, however experience of energy assessment or inspection of large commercial buildings would be an advantage. Candidates already qualified as a NDEA will not need to attend the training module on building construction and services.

Course Duration

The course duration is 5-8 weeks.

The ORCalc software is free to use, subject to licence. Alternative OR software is expected to be commercially available shortly.
