Towards the end of last year, I was fortunate enough to be in South Africa for the September meeting of SAIRAC (South African Institute for Refrigeration and Air Conditioning). Better yet, they had asked me to speak about our wireless BEMS, how it can improve install times and how it can, in general be used in place of a traditional hard-wired building energy management system. The gains afforded by a wireless system not only include a better return on investment for the client, but offer a competitive advantage to the integrator, allowing them to install quicker, with less disruption and in a greater spectrum of buildings.

South African energy market

Between 2014 and 2015, South Africa’s power prices increased 8.2% to 8.46 US cents per kilo-Watt hour (kWh) – the second biggest jump, behind Belgium’s 9.9% increase. This is likely to be the last single-digit increase for the country, NUS said, as a 12.69% jump in prices has been approved in the coming year, with more increases likely to follow.


As South African energy price continue to creep up (prices increased 8.2% between 2014 and 2015), I expect more and more businesses to become interested in using to reduce their energy costs. For those with a current BEMS installed, it could be the extension of this system (using our wireless IO) to new areas that were previously uneconomic to cover with a traditional, wired system. For those with no system at all, a WEMS wireless BEMS, could provide the perfect solution.
