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.

Two academics will be sorely missed

The staff and students of the University of the Free State (UFS) are deeply saddened by the recent passing in Bloemfontein of two of the university’s most esteemed and renowned academics, Prof Bannie Britz and Prof Andrew Marston.

Prof Britz was the Head of the Department of Architecture from 1992 to 2000. He was renowned in his field, winning numerous prizes for Architecture, including the Gold Medal for Architecture from the South African Academy of Arts and Sciences.

“As professional architect and urban designer, Prof Britz was a much awarded architect who received numerous award of merit from the South African Institute of Architects for buildings erected in South Africa over the years,” said Martie Bitzer, Head of the Department of Architecture.

Apart from his acclaim elsewhere, Prof Britz also played a major role in the day-to-day activities of university’s staff and students. He was responsible for the design of the many walkways on campus and the refurbishment of the Main Building on the Bloemfontein Campus. For the many contributions in his field, Prof Britz was awarded an Honorary Doctorate by the UFS in 2007.

Prof Andrew Marston, a specialist in natural product chemistry and methods associated with the isolation and analysis of medically important chemicals from plants, was appointed from Geneva, Switzerland in 2009 under the UFS Strategic Cluster for Advanced Biomolecular Research.

He obtained a B-rating from the National Research Foundation (NRF) in 2011, and was consequently appointed as a senior professor in die UFS Senior Professor Programme. “He has made valuable contributions to the UFS in terms of teaching and postgraduate supervision, as well as research. In his short stay at the UFS, he already co-authored more than ten papers in international chemistry literature,” said Prof André Roodt, Head of the Department of Chemistry.

His research group was part of a multilateral agreement in the European Union (EU) with a number of African and three European universities. He obtained new research funding from the Seventh Framework Programme of the EU for the Building Sustainable Research Capacity on Plants for Better Public Health in Africa project, from the Norwegian Research Council for bioprospecting and the isolation and structure determination of compounds from plants and algae, and from the South African Rooibos Tea Council.

The memorial service for Prof Britz took place on Friday 5 April 2013 in the Berg-en-Dal Dutch Reformed Church in Bloemfontein. The service for Prof Marston took place in the Trinity Church, Charles Street, Bloemfontein.
