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.

Fresh new look for UFS Sasol Library

The UFS Sasol Library on the Bloemfontein Campus has been renovated with a fresh new look to cater for the changing study needs of students. Over the last few months several upgrades have been made to ensure that students get an effective learning experience.

These upgrades will be spread over three phases. Upgrades include newly-built overnight study facilities, partitioned study areas for postgraduate students and areas for leisure reading. Special attention has also been given to security, with the access control system and the tattle-tape security system being moved to the foyer on Level 2. This level, which used to serve only as a thoroughfare to and from the eastern and western parts of the library, has been turned into proper foyers on either side.

"The UFS Library and Information Services are on a mission to present itself as the physical and virtual information hub of choice," says Director Betsy Eister. "The increased intake of new students and technological developments has sparked the notion of new and revamped study spaces conducive to learning.”

Eister says that, after the completion of all three phases, the library will have increased study spaces that appeal to different people with different needs – spaces for studying, leisure reading, newspaper reading, accessing wired and wireless connections and spaces for discussions.

The project which started in October 2012 is part of the university's space-planning projects to optimally utilise space on the Bloemfontein Campus. The project will also see the Centre for Teaching and Learning move to Level 3 of the library.

Hendri Pretorius from the Department of Architecture was the Project Leader responsible for the upgrades to the Library.
