SANS 10400-XA:2021 - National Building Regulations: Energy usage in buildings

The national standard SANS 10400XA is mandatory for all new buildings. The code stipulates the energy usage criteria that buildings would have to comply to.

In terms of compliance with SANS 10400XA, buildings can choose between the prescriptive route and the reference building or performance route. The reference building route is similar to the performance route, except that it uses the energy performance of a reference building (with strict application of the prescriptive route) as the basis of compliance. 

The code was last updated in 2021.
