Level 3 – Certificate in Non-Domestic Energy Assessment

Non Domestic Energy Assessor (NDEA) L3
A Non-Domestic Energy Assessor (NDEA) is a certified individual who undertakes energy calculations, using approved Simplified Building Energy Model (SBEM) or Dynamic Simulation Modelling (DSM) software on commercial buildings. The calculations produce a commercial Energy Performance Certificate (EPC). All commercial buildings in the UK require an EPC before marketed sale or let.

The Level 3 Non-Domestic Energy Assessor (NDEA) qualification allows assessors too complete EPCs on all existing commercial buildings with frequently occurring characteristics – this covers a large proportion of the Non Domestic market.
