Non-Domestic Energy Assessor Level 5 Accreditation

Elmhurst’s Non-Domestic Energy Assessor (NDEA) Level 5 Accreditation Scheme is open to energy assessors trained and qualified to complete energy calculations, using Dynamic Simulation Modelling (DSM) software for complex commercial buildings.

Elmhurst’s NDEA Level 5 accreditation scheme ensures members have the skills and knowledge to deliver professional energy assessments, and lodge Energy Performance Certificates for Commercial Buildings across England and Wales. 

Level 5 commercial buildings are considered to be the most complex buildings to produce energy assessments for. A Level 5 non-domestic property can be identified from specific features such as atriums, automatic blind control and ventilation with enhanced thermal coupling. However, more often than not, a Level 5 Building will be very large in size.

Elmhurst's accept Level 5 lodgements through approved DSM software, such as DesignBuilder.
