Development and verification of a TRNSYS energy system simulation model for a combined heat and power dual-fuel system
(North-West University, 2019)Many companies suffer economic losses due to unannounced, interrupted power supply caused by electricity cuts. These companies then purchase electricity generator units to supply electricity during these times. This however, ... -
Ensuring long-term energy savings in South African mines by improving energy data
(North-West University (South Africa), 2021)South African mines experience higher-than-inflation electricity tariff increases, additional expenses such as carbon taxes and mounting environmental obligations. The mining sector is, therefore, forced to maintain long-term ... -
Evaluating different statistical regression models for industrial energy measurement and verification
(North-West University (South Africa), 2020)The worldwide concern regarding the environmental impact of using fossil fuels as an energy source leads to the increased interest in improving energy efficiency. The energy efficiency of existing facilities can be improved ... -
An integrated methodology to measure and verify energy conservation under incentive-based irrigation pumping programmes
(North-West University (South Africa), 2019)Water scarcity and droughts have become a looming threat in many counties worldwide. In South Africa, a water crisis is upon the country and estimations show a supply shortfall of 17% by 2030. When considering water ... -
Management of measurement and verification uncertainty for industrial 12L tax incentive applications
(North-West University (South Africa), 2019)South Africa (SA) has committed to reducing its greenhouse gas (GHG) emissions. One of SA's key strategies to minimise GHG intensity is to utilise incentivised energy efficiency initiatives (EEIs). Specifically, the section ... -
Novel solutions for compressed air demand management on deep-level mines
(North-West University (South Africa), 2020)Mining makes a significant contribution to South Africa’s economy (7.3% of the gross domestic product) and provides direct employment to more than 450 000 people. The bulk of South Africa’s mineral wealth lies in deep-level ... -
Sustainable use of inlet guide vanes to reduce energy consumption of main ventilation fans
(2021)The rising cost of electricity has urged mines to research and implement new energy-saving initiatives. Little research has focused on energy saving techniques on main ventilation fans (MVFs). MVFs extract hot, humid air ... -
Using simulation to prioritise implementation of platinum mine compressed air efficiency solutions
(North-West University (South Africa), 2021)Platinum mines are facing several challenges and a higher-than-inflation increase in electricity costs is amongst the most significant. Compressed air accounts for up to 38% of a platinum mine’s energy consumption. To ...
