Solar Panels at UFS Qwaqwa Campus
Revolutionising electricity with sun power: Solar panels at the Qwaqwa Campus.

Over the past few years the University of the Free State (UFS) has been planting panels, now the time has come to reap. Solar farms produced a return on investment in the form of R1.4 million in savings as a result of photovoltaics (PV) between January and March 2019. Nicolaas Esterhuysen, an electrical engineer at the Department of University Estates also reported a 2.34% decline in electricity usage between 2013 and 2018. 

Solar panels are the future 

According to Esterhuysen, the solution to a power crisis lies in “either becoming more energy efficient or generating our own at a cheaper cost”. All campuses have managed to save a total of R5.4 million in 2018 through producing our own power (solar PV) and actively managing the instantaneous load demand with building management system (BMS) software.

Overall, ground-mounted PV installations at all campuses contribute 2609 kilowattpeak (kWp) under standard conditions. The Bloemfontein Campus accounts for 979kWp of that amount while the South Campus generates 762kWp, with the Qwaqwa Campus producing 748kWp, and the Paradys experimental farm bringing in 120kWp to the grand total (to be commissioned June 2019).

Rooftop PVs generate electricity through the 80kWp Muller Potgieter Building, the 255kWp Bloemfontein Campus computer lab, the 35kWp Qwaqwa Campus computer lab, 135kWp Qwaqwa Campus Mandela Hall, and 416kWp Thakaneng Bridge panels. This is a total of 921kWp. 

Winter is coming with tariff terrors 

A 15.63% electricity tariff increase is projected this year in light of the annual winter adjustments commissioned by Eskom and Centlec. To gear up for the associated spike in power use over this season, University Estates advises the Kovsie community to use energy efficiently. “Think twice before switching on the heating and make sure to switch it off when you leave the office,” advises Esterhuysen.

In addition to generating electricity, saving initiatives such as implementing light-emitting diode (LED) lighting with motion sensors and actively managing demand at peak times have been implemented.

What’s next?

The next step is to rethink dated mechanical installations that are used to heat some of our older buildings. Replacing similar installations across all of the campuses are some of the ways the university intends to escalate energy efficient in future.

“This new development will strengthen the long-lasting collaboration between DiMTEC and the United Nations University, Institute for Environment and Human Security (UNU-EHS) in Bonn in Germany. This [collaboration] goes back for almost a decade of joint training courses and increasingly also includes collaboration in the frame of scientific projects, especially in Africa.”

These were the words of Dr Joerg Szarzynski after his appointment as Affiliated Associate Professor to the Disaster Management Training and Education Centre for Africa (DiMTEC) at the University of the Free State (UFS). Dr Szarzynski will assume his new position with immediate effect.
 
The United Nations University (UNU) is a global thinktank and postgraduate teaching organisation headquartered in Japan.

Dr Szarzynski, head of the EduSphere section and Education Programme Director at UNU-EHS, brings with him a wealth of experience, including serving as senior expert to the United Nations Platform for Space-based Information for Disaster Management and Emergency Response (UN-SPIDER). Within the team, he was principal desk officer for Africa responsible for relief activities after natural disasters, technical consultation, information management, collaborative network development and the cluster on health and climate change adaptation. He also has broad expertise in climatology and remote sensing, global environmental change research, capacity-building and web-based data and information management.

“Dr Szarzynski’s appointment brings
new research opportunities.”

Lecture focus on vulnerability and disaster risk reduction
As part of his new academic responsibilities, Dr Szarzynski will conduct face-to-face lectures during a course on vulnerability and disaster risk-reduction. With this course the centre aims to increase awareness of the complexity and importance of vulnerability and resilience in the field of disaster risk management. Dr Szarzynski’s teachings will focus on Early Warning Systems and Geospatial Technologies in Support of Disaster Risk Reduction (DRR) and Emergency Response Preparedness. He will also lead courses on Assessment and Coordination in International Disaster Management and Humanitarian Response and Information Technology in Disaster Risk Reduction and Disaster Management.

Furthermore he will give lectures via distance learning for the wider curriculum at DiMTEC.

Collaboration between DiMTEC and UNU
Dr Andries Jordaan, Director of DiMTEC at the UFS said: “His appointment opens new networks within the United Nations system, which brings new research opportunities. Furthermore, his expertise is important to us. He has already provided input and delivered lectures through Skype in the course of Information Technology and Communication.”

Dr Szarzynski has been lecturing for the past 10 years in the UFS’ international PhD curriculum.
