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 ...
The design and implementation of information systems for ESCO energy savings software
(North-West University, 2003)
Electricity cost of buildings is a major expense for building owners. Improvements in the efficient utilisation of energy is therefore of concern to this economic sector. Unfortunately, existing energy audit tools are ...
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 ...
Assessment of the national DSM potential in mine underground services
(North-West University, 2003)
ESKOM is moving towards a price structure for electricity which reflects, as far as
possible, the real cost of generation. It is called real time pricing (RTP). ESKOM
developed this cost structure to coax customers to ...
New standards of thermal design to provide comfort and energy efficiency in South African housing
(North-West University, 2003)
The fundamental objective of this thesis is to determine whether the requirements for thermal comfort in housing in South Africa will provide for the necessary levels of energy efficiency. The effectiveness of various ...
Solar heating and disinfection of water : an application for rural areas in Southern Africa
(North-West University, 2003)
Life is not easy for the low-income rural population of Southern Africa. This includes
those living in the informal settlements around cities. It is in part due to shortcomings in basic services such as water, sanitation ...
Advanced linear methods for T–tail aeroelasticity
(North-West University, 2011)
Flutter is one of the primary aeroelastic phenomena that must be considered in aircraft design. Flutter is a self-sustaining structural vibration in which energy is extracted from the air flow and transferred to the ...
Methods to optimise underground mine production
(Potchefstroom University for Christian Higher Education, 2002)
The focus of this study was to investigate the current underground conventional mining systems used in the platinum mining industry and to design a mine production planning system to optimise the conventional operations - ...
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 ...
An integrated sustainability framework for environmental impact reduction in the gold mining industry
(2014)
The gold mining industry pollutes both water and air resources in numerous ways. Of these, air pollution from greenhouse gasses inducing climate change poses the highest threat to human existence, with water scarcity as a ...
