SBEM Calculations for Northern Ireland

SBEM Calculations for Northern Ireland 

Simplified Building Energy Model (SBEM) assessments are designed for commercial new builds. 

What is an SBEM calculation?

An SBEM calculation predicts the energy performance of commercial buildings in order to prove compliance with Part F of the Building Regulations. The results of an SBEM calculation are used to produce an Energy Performance Certificate (EPC), which is needed before being sold or let.  

Two SBEM calculations need to be performed: 

Design Stage (before the building is constructed). This must be completed and submitted to your Building Control Body or Approved Inspector at the same time as your Building Control Application. 

As-Built (after construction). Once your building is completed a 'pass' certificate must be presented to your inspector. The final certificate will detail any changes to the building since the Design Stage SBEM and will also include your certified air test results. 

It takes into account:

  • Ventilation characteristics
  • Thermal insulation
  • Materials used 
  • Fuel used to produce space and water heating
  • Efficiency and control of the heating system
  • Renewable energy technologies (if applicable)

Does my building need a SBEM calculation?

Most new commercial buildings over 50mwill require an SBEM. Some extensions, conversions and renovations will also require an SBEM, however there are some exceptions. 

Buildings that do not require an SBEM include places of worship, temporary buildings and unheated units. 

All new commercial buildings require a SBEM calculation in order to demonstrate compliance with Building Regulations. However, there are a few notable exceptions.
