SANS 10400-XA:2021

SANS 10400-XA is currently under review, with the proposed draft standard having been published. 

If the proposed standard is adopted in its current format, the regulation changes can be summarised as follows:

  1. SANS 204 will fall away and will be integrated into the new SANS 10400-XA.

  2. SANS 1544 is going to be implemented on all new buildings. (SANEDI: non-residential buildings are going to display their energy performance certificate by December 2022)

  3. SANS 10400 XA – 6 Climatic zones fall away, and the 7 energy zones are implemented.

  4. SANS 10400 – window ratio has increased to 20% from 15%, but garage and patio areas are no longer included in footprint.

  5. SANS 10400 will now require shading calculations for all new submissions.

  6. Southern Cape Condensation Problem Area – Low E glass for single glazed applications will not be approved. (Double glazing is the solution)
