By December 2022, it will be mandatory for non-residential buildings of certain sizes to publicly display an energy performance certificate (EPC) at their entrance, in accordance with regulations passed by the Department of Mineral Resources and Energy in a move to monitor and encourage energy efficiency in buildings.

The GBCSA notes that ‘knowing the energy performance of a building empowers potential buyers or tenants to make a more informed decision’, and that ‘the first step toward lowering energy consumption is knowing energy consumption’.

According to Barry Bredenkamp, GM of energy efficiency and corporate communications at the South African National Energy Development Institute (SANEDI), ‘the regulations apply to non-residential buildings with a net floor area of at least 2 000 m2 in the private sector, and 1 000 m2 for buildings owned, operated or occupied by an organ of state’. A  building’s energy-use intensity will be measured and given a colour-coded score, from A to G.

‘Buildings must try achieve at least a D-rating, which is on par with the national benchmark,’ says Bredenkamp.

To obtain an EPC, the building owner must collate specific information (including the electricity consumption data over a 12-month period; the net floor area; information on the areas excluded; and vacancy rates) and contract a SANAS-accredited inspection body to audit the information. The result grade is submitted to SANEDI, which adds it to the National Building Energy Performance register.
