SBEM Assessments and L2 Compliance
What is SBEM? SBEM stands for Simplified Building Energy Method (SBEM), the standard method for validating your commercial building’s compliance with current Building Regulations (Part L, 2021). An alternative is Dynamic Simulation Modelling (DSM), which ensures your building meets necessary energy performance standards.

Why SBEM?
SBEM provides a detailed analysis of your building’s energy performance, ensuring compliance with regulations. By simulating heating systems and emission characteristics, SBEM offers a precise representation of your building’s energy use. For new non-domestic buildings, these calculations are mandatory to avoid non-compliance and potential fines.

DSM software in SBEM
DSM software usage guarantees a very accurate representation of the building‘s real energy performance in the EPC model. Importantly, this accuracy is preserved while following regulated SBEM conventions. The simulation is particularly good at simulating the heating systems and emission properties of a building‘s fabric, giving a detailed and accurate representation. In addition, our method provides higher flexibility when assigning equipment to the respective zones than models such as iSBEM Software, which facilitates a more flexible and subtle evaluation.
If you are constructing a new non-domestic building, it is mandatory to conduct these calculations. Failure to do so may lead to non-compliance and result in fines.
