  • Abstract:
    The six-region climatic map used in the current South African National Standards SANS 10400XA and SANS 204 does not support quantified design decisions within the built environment or indicate the amount of cooling and heating energy required per climatic region. An alternative set of maps based on interpreted degree-days is presented and can be used for regulation and design strategies. A dataset of 21 years of hourly, 0.05-degree data was used to produce a map with discrete heating and cooling degree-day classes. The resultant zones are therefore not derived from only the dominant climatic characteristics, but from simultaneous annual heating and cooling demands. The advantage is that the new map enables adaptive building design for climates with significant diurnal or annual temperature swings, making it useful for regulators and designers. A good correlation exists between the developed degree-day indices and building energy. The majority of South Africa was found to fall within the medium heating/medium cooling zone as expected; however, the KwaZulu-Natal coastal region is within the medium cooling zone and not the expected high cooling zone. This may be due to the humidity levels that are not accounted for.
