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.

The Department of Quantity Surveying at the University of the Free State (UFS) has much to be proud of. With Prof Kahilu Kajimo-Shakantu as Head of the Department of Quantity Surveying, the department is celebrating several firsts.

For the first time, the department has four academics with PhDs. This includes Prof Kajimo-Shakantu, Dr Stephan Ramabodu, Dr Timothy Froise and Dr Benita Zulch. It is also the first time that this department is managed by a woman.

Furthermore, the Department of Quantity Surveying has performed very well at this year’s national Quantity Surveying Conference held in Pretoria, where they walked away with four of the seven awards.

The awards were:

•    Best presenter: Pierre Oosthuizen (lecturer)
•    Most innovative presenter: Pierre Oosthuizen (lecturer)
•    Best paper on engineering projects: Prof Kahilu Kajimo-Shakantu
•    Best academic paper: T Monyane (postgraduate student) and Dr Stephan Ramabodu (lecturer)

The South African Council for the Quantity Surveying Profession (SACQSP) also presented two prestigious life achievement awards. One of these were bestowed upon Prof Basie Verster from the UFS for his contribution to quantity surveying since the 1970s.

The university is especially proud of Dr Stephen Ramabodu, lecturer in the Department of Quantity Surveying, who completed his PhD this year. This makes of him the highest qualified quantity surveyor in the department and one of only a few holders of a quantity surveying PhD in the country. Dr Ramabodu is also registered with the South African Council for Quantity Surveying Professionals.

Prof Kajimo-Shakantu said the following of Dr Ramabodu. “Since 2002, Stephan was appointed as a lecturer in a programme called Grow Your Own Timber at the UFS. Later on, he went to Cape Town to gain some commercial experience, where he worked for Davis Langdon in 2005. In 2008, he returned to the Free State, where he established Ramabodu & Associates. Later on in the same year, he returned to the UFS as a lecturer to complete all the remaining milestones of the Grow Your Own Timber programme.

“The university looks forward to Stephen’s increased responsibilities and contributions, not only in teaching and learning, but also in research, mentoring and community engagement.”
