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 ...
Developing ESCO procedures for large telecommunication facilities using novel simulation techniques
(North-West University, 2006)
Peak electricity demand in South Africa will exceed the available operational generation
capacity in 2007. The state utility Eskom is addressing this challenge, inter aha, with the
implementation of the Demand-side ...
The development of a methodology to measure & verify the impact of a national solar water heating program
(North-West University, 2010)
The School for Mechanical Engineering at the North-West University is home to one of South Africa's most established Measurement & Verification (M&V) teams. The team is involved with South Africa's electricity utility, ...
The cost-effectiveness of comprehensive system control on a mine compressed air network
(2014)
Compressed air leakage accounts for up to 42% of electrical energy loss on a typical mine compressed air system. By using underground control valves it is possible to reduce the amount of air leakage. Underground valve ...
Implementing DSM interventions on water reticulation systems of marginal deep level mines
(2014)
Because of a continuous increase in the demand for electricity in South Africa the country’s largest electricity utility (Eskom) has been under strain to provide electricity. An expansion programme to generate more electricity ...
Cost savings on mine dewatering pumps by reducing preparation– and comeback loads
(2014)
Using chilled water within South African gold mines is paramount to the purpose of extracting gold ore efficiently. Using water for cooling, drilling and sweeping and the release of underground fissure water causes the ...
Reconfiguring mining compressed air networks for cost savings
(2014)
The world is currently experiencing major issues in the energy sector. The ever-growing human population, limited energy resources and the effect of greenhouse gas emissions have become major global concerns for the energy ...
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 ...
Integration of DSM interventions into bulk water supply strategies
(North-West University (South Africa) , Potchefstroom Campus, 2015)
Supplying water to communities, industries and agricultural developments within South Africa is a cardinal task undertaken by the Department of Water Affairs (DWA). South Africa is a water-scarce country with an uneven ...
Challenges faced during implementation of a compressed air energy savings project on a gold mine
(2014)
Demand side management (DSM) initiatives have been introduced by Eskom to reduce the deficit between the electricity generation capacity and the electricity usage within the country. DSM projects enable Eskom to reduce ...
