Castle Square, Elephant and Castle

Energi IQ recently completed 21 no. Part L SBEM Calculations and ‘On Construction’ Non Domestic Energy Performance Certificates for the new retail development at Castle Square in Elephant & Castle.

The retail spaces at Castle Square features shops, hairdressers, restaurants and cafe’s. It will be home to local independent traders who have a long history of being based in Elephant and Castle.

Under Part L2 of the Building Regulations, all new Non-Domestic buildings must pass a Simplified Building Energy Model (SBEM) calculation.

SBEMs are used to create the BRUKL compliance document and the Energy Performance Certificate. They measure heat loss through the building fabric, available sunlight and air permeability. These are then combined with the energy required for heating, cooling, hot water, lighting and ventilation and any renewables supplying the building to measure the overall energy efficiency and carbon emission rates of buildings.

SBEM calculations are required by Building Control departments, and they are required at two stages, at design stage to check for compliance and at completion to reflect any changes that may have been made during the construction phase.
