Weathering the winter with energy efficiency

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.

Prof. Johan Henning, Dean of the Faculty of Law at the University of the Free State (UFS) and Head of the Centre for Business Law at this faculty, delivered three papers during this year’s Cambridge International Symposium on Economic Crime that took place at Jesus College at the University of Cambridge in Cambridge. The theme of this 27th symposium was: “The enemy within – internal threats to the stability and integrity of financial institutions”.

Prof. Henning’s presentations were about: “Conflicts of interest and duty – a persistent threat”, “Data security and identity fraud” and “The responsibility of management for the prevention and control of financial crime-related risks”.

Over and above the three papers he delivered, Prof. Henning was also part of the secretariat of the symposium and he acted as chairperson at some of the workshops.

The UFS’s Faculty of Law was once again very much involved in the organisation and participation of the symposium. Since 1992, the Centre for Business Law of the Faculty of Law has been one of a few organising institutions of this popular and well-known symposium.

Prior to the symposium, Prof. Henning also acted as guest professor at the week-long Hosei Summer School Project that is presented by the Faculty of Law of the Hosei University (Tokyo Japan) in cooperation with the University of Cambridge. He presented two extended workshops for LLM students on International Business Law and Comparative Company Law.

Prof. Henning is also a Professorial Fellow at the Jesus College and a principal lecturer in International Mercantile Law at the Hosei University Summer School.
