SBEM is used to create models and simulations of the proposed building, when compared against a notional building of the same dimensions and functionality, via the National Calculation Method Database. An improvement factor is then applied to establish a Target Emission Rate (TER) against which the actual design Building Emission Rate (BER) must equal or better.

The majority of this work is a desk-based exercise utilising approved software. The start point for the creation of SBEM calculations is for one of our certified SBEM assessors to review the detailed plans, drawings and specifications, including building fabric and mechanical and electrical installations, and to prepare the formal SBEM Report for submission to building control.
