An energy efficient mass transportation model for Gauteng
(North-West University, 2011)
Public transportation in South Africa is characterized by little or no consideration for energy efficiency and use of cleaner fuels. In the case of transport planning in South African cities, no assessment of the economic ...
Investigation, development and testing of a low cost Solar Heat Barrow (SHB) and purifier
(North-West University, 2003)
Many rural communities in South Africa do not have running water or electricity. The fetching and heating of water is therefore a time consuming and expensive daily ritual. The use of energy sources such as wood or coal ...
A new integrated procedure for energy audits and analyses of buildings
(North-West University, 2003)
A rapid growth in the national electricity demand is placing an ever-increasing demand on the national electricity supply utility, Eskom. Projections show that the load demand in South Africa may exceed the installed ...
Sustaining compressed air DSM project savings using an air leakage management system
(North-West University, 2010)
Unreliable and unsustainable electricity supply has been experienced in South Africa since
2007. Eskom implemented Demand Side Management (DSM) as a short-term solution to
alleviate this problem. Several compressed-air ...
Energy efficiency opportunities in mine compressed air systems
(North-West University, 2009)
Demand Side Management (DSM) is one of the most viable and sustainable short term methods to address the shortfall in electricity generation in South Africa. This is because DSM projects can be implemented relatively ...
A variable water flow strategy for energy savings in large cooling systems
(North-West University, 2013)
Large cooling systems consume up to 25% of the total electricity used on deep level mines. These systems are integrated with the water reticulation system to provide chilled service water and cool ventilation air. Improving ...
The adaptive predictive control of an energy efficient central water heating system applied in the South African commercial sector
(North-West University (South Africa), Potchefstroom Campus, 2016)
Since the introduction of load shedding in the latter part of 2007, Eskom, the electrical
utility of South Africa, have been forced to implement energy efficient and energy management
measures to ensure the stability of ...
Sustained energy performance on compressed air systems for expanding gold mines
(2013)
The energy provider in South Africa, Eskom, faces an increasing electricity demand. The need to ensure sufficient supply gave rise to Demand Side Management (DSM) projects scheme. The DSM focus has shifted to the mining ...
A unique energy–efficiency–investment–decision–model for energy services companies
(2008)
To remain competitive in an environment with limited natural resources and ever-increasing
operational costs, energy efficiency cannot be ignored. From this perspective the need for
Energy Service Companies (ESCos) has ...
Energy efficiency through variable speed drive control on a cascading mine cooling system
(2014)
An ever-expanding global industry focuses attention on energy supply and use. Cost-effective electrical energy production and reduced consumption pave the way for this expansion. Eskom’s demand-side management (DSM) ...
