What does a DEC Assessor do?
Public buildings which have a total floor area over 250 square metres and which are frequently visited by the public, are required to have a Display Energy Certificate (DEC) displayed publicly. As a trained DEC Assessor, you will have the relevant knowledge to assess the energy use of buildings within the public sector (hospitals, doctors, libraries, schools, council buildings etc). You’ll use approved Operational Rating (OR) software to produce the required energy certificate and advisory report.
DEC assessments require work to be undertaken on site with data entry completed back at home or in the office. Assessors will collect observations about the building’s heating, lighting and ventilation systems, using documents provided by the building owner to determine how the building is used.
The time it takes to complete a typical DEC assessment depends on the size of the building. A small public building may only take 1-2 hours, whereas a large site with multiple floors or buildings (such as a hospital) could potentially take up to a week. Multi-building sites will always take longer to complete, but having the Facilities Manager of the site on hand is always helpful and can speed up the process.
