5.2 What an energy assessment involves

The SBEM or DSM software assesses the energy demands of each individual space in the building in accordance with the activity conducted within that space (examples being office space, kitchens, storage space etc). Different activities can result in different periods of occupancy and different required temperatures, as well as varying requirements for lighting and hot water supply. The energy consumption and carbon dioxide emissions are calculated by considering these demands in relation to the details of the building services.

The energy assessor will need to understand the internal layout of the building and for what purpose it is used. The energy assessor will need to validate (via plans and/or physical survey) zone distances, thermal insulation and building services.

The SBEM software will use the information provided by the assessor and standard performance tables and will produce the EPC and recommendation report.
