The challenge is set in various sectors - including the built environment sector - to respond to climate change, for example, by making use of passive building design strategies. The CSIR created a new Köppen-Geiger map to quantify the current South African climatic conditions using temperature and precipitation data from1985 to 2005. Algorithms described by Kottek (2006) were used to compile the map on a 1 km x 1 km grid. The Köppen-Geiger map is now available online on the StepSA website for free use as part of a series of climate indicator maps.

The Köppen-Geiger classifications consider five primary categories as follows:

The classifications system further considers six secondary categories as follows:

Insights & Findings

Thirteen distinct climate zones appear in South Africa when mapped according to Köppen-Geiger.


These climatic zones can be associated with a selection of passive design responses, which could be effectively deployed in those zones.
