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 ...
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 ...
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 ...
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 ...
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 ...
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 conceptual design of an integrated energy efficient ore reduction plant
(2014)
This study explores ways to determine the energy efficiency of a pyrometallurgical ore reduction plant and measures to improve it. The feasibility of building a commercial plant - that is more energy efficient, has a low ...
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 ...
Modernising underground compressed air DSM projects to reduce operating costs
(2014)
Growing demand for electricity forces suppliers to expand their generation capacity. Financing these expansion programmes results in electricity cost increases above inflation rates. By reducing electricity consumption, ...
