For mixed-use schemes
Mixed-use package: SAP and SBEM coordinated as one instruction
A building with flats above shops, offices or other commercial space needs two kinds of modelling: SAP for the dwellings and SBEM for the non-domestic areas. This package runs both under one instruction, so the shared elements, boundaries between uses and communal services are treated consistently, and one person answers for the whole building.

What you get
Everything this package covers.
SAP for the dwellings
Design-stage and as-built calculations for each flat type, plus the on-construction EPC for each dwelling.
SBEM and BRUKL for the non-domestic areas
Each commercial area modelled, with the BRUKL output and the non-domestic EPC where one is required.
Consistent treatment of shared elements
Party elements, communal plant and shared services modelled once and applied consistently on both sides.
One coordinated evidence set
Domestic and non-domestic outputs issued together rather than as unrelated reports arriving weeks apart.
