Non-Domestic Energy Assessment (NDEA)

• What is Non-Domestic Energy Assessment (NDEA)?

What is Non Domestic Energy Assessment (NDEA)?

Energy Performance Certificates (EPCs) are now mandatory upon construction, sale or rental of any non-domestic building, whether new or existing. An assessment must be carried out by an accredited assessor and an EPC generated, which gives the building a rating of 'A' to 'G' (where 'A' is the most energy efficient).

The EPC is also accompanied by an Advisory Report (AR) which outlines ways in which energy can be saved and provides recommendations that include the short, medium and long term paybacks of various green technologies. The implementation of these recommendations would reduce the building's CO₂ emissions as well as fuel costs.

Approved Document L2A-2006 of the Building Regulations stipulates a full building energy calculation for all newly constructed buildings. The Simplified Building Energy Model (SBEM) software used to produce this documentation is then used to create the EPC which is required prior to the building being occupied.

Diploma in Non-Domestic Energy Assessment - Level 3

Stroma offers the Level 3 Diploma through a choice of two awarding bodies, ABBE or City & Guilds. For either qualification, candidates attend a 4 day training course where they are taught the practical skills of building surveying and data entry into the approved government software.

A level 3 NDEA can model simple heating, cooling and ventilation systems within existing buildings.

After completing the training, candidates sit a multiple choice examination and produce a portfolio of three EPCs and supporting documentation to demonstrate their ability to carry out non domestic energy assessments.

Diploma in Non-Domestic Energy Assessment - Level 4

For candidates who wish to assess and produce EPCs for buildings containing more complex heating, cooling and ventilation installations in both existing and newly constructed buildings Stroma offers the Diploma in NDEA Level 4. The syllabus is offered as a 2 day (top-up) course which builds on the knowledge acquired for the Level 3 Diploma.

In addition to the level 4 training course, candidates have the option to attend a 1 day follow-on course for DECs.

Similar to the Level 3 Diploma the candidates will become qualified once they have passed the multiple choice exam and produced the Portfolio of 3 EPCs.

Level 5

Level 5 assessors are qualified to undertake assessments on both existing and newly constructed non-domestic buildings using Dynamic Simulation Modelling (DSM). Accreditation to this level can only be gained through the APEL route.

APEL (Accreditation of Prior Experiential Learning)

For experienced candidates possessing the skills required to use SBEM & DSM, there is a fast track option: APEL. Candidates may apply to be assessed for APEL to level 3, 4 or 5. To satisfactorily complete this application supporting information is required to demonstrate competence against the National Occupational Standard (NOS) framework in conjunction with the submission of relevant projects for technical appraisal.

Certification

Once qualified, assessors are invited to join Stroma's certification scheme. Our experienced NDEA technical team are available to offer support to all assessors. Stroma accredited assessors will gain access to the Stroma members area online, receive regular technical bulletins and regular CPD events and workshops.
