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.

This year the Faculty of Law at the University of the Free State (UFS) is celebrating a century of excellence in legal education under the theme “Iurisprudentia 100”. A number of prominent leaders in the international legal arena congratulated the faculty on this milestone achievement.

Prof. Harry Rajak, Emeritus Professor from the Sussex Law School at the University of Sussex in the United Kingdom communicated his heartiest congratulations to the faculty. “It has been my great privilege and pleasure to have had, for many years now, a close association with the Faculty of Law of the UFS. I have enjoyed several visits to the Law Faculty, during which I have benefited enormously from the vibrant intellectual, scholarly and extremely friendly atmosphere which you have all created, as well as from the enthusiasm and intelligence of your students. I look forward to the continuation for many more years of this important and fruitful connection,” he said.

Prof. Barry Rider from the Institute of Advanced Legal Studies at the Jesus College at Cambridge University in the UK also congratulated and expressed his admiration towards the faculty. “The reputation for excellence in the teaching of law and in its scholarly research that your faculty has attained both in the Republic and internationally is a testament to the outstanding efforts and commitment of so many generations of scholars in Bloemfontein. I have been extraordinarily privileged to be associated with your faculty. The achievements of your faculty are truly impressive,” he said.

The faculty also received wishes of congratulations from Prof. Thomas Hurst, Research Scholar and Professor of Law from the Levin College of Law at the University of Florida in the United States of America. “The UFS has established itself as a world renowned leader in legal education,” he said.

Mr Anton Trichardt from Londsdale Chambers, Melbourne Australia also conveyed his best wishes to the faculty. “Your Faculty of Law has indeed been an example of excellence in legal education, training and research. The Centre for Business Law and its monograph series has been an unrivalled trend-setter in law,” he said.

Old Mutual also conveyed its wishes of congratulations.
