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.

Cohesions and Disruptions Forum
2014-07-15

 
The Institute for Reconciliation and Social Justice at the UFS and the Johannes Stegmann Art Gallery, in partnership with the Vryfees, co-presented an artist and academic forum on 18 July 2014.

The forum, ‘Cohesions and Disruptions: Art as a Key to Transformation’, was aptly timed to coincide with Mandela Day. This event formed part of the transformation strategy of the Vryfees arts festival, aiming to support more diversity and cross-cultural, contemporary art programmes.

“Cohesions and Disruptions is part of the new Program for Innovation in Artform Development (PIKO/PIAD),” said Adri Herbert, Director of the Vryfees. “This includes both the cross-cultural OPENLab 2014, a new Australian/South African laboratory for early and mid-career South African artists, and a partnership with the Australian based SituateArt in Festivals initiative, managed by Salamanca Arts Centre in Hobart, Tasmania.”

The forum’s keynote speaker was Lee-Ann Tjunypa Buckskin. She is a Narungga, Wirangu, Wotjobaluk woman from South Australia and Victoria respectively. She is well known throughout the Aboriginal and Torres Strait Islands and broader arts communities. Buckskin’s presentation was titled ‘Building Young Indigenous People’s Lives through Art and Culture in Remote Central Australia.’

Buckskin spoke broadly about her involvement with youngsters – often poverty stricken and sniffing petrol – in remote areas of Australia. She explained how the arts have given the youth a chance at rehabilitation and hope for the future.

After her presentation, she was joined by Dr Willy Nel, lecturer at the UFS School of Education Studies. Dr Nel completed his PhD among the Khomani San in the Kalahari. 

Other forum speakers who presented their work included:
Dr Mari Velonaki, Director of the Centre for Social Robotics at the National Institute for Experimental Art at the University of New South Wales, Sydney;
Dr Nigel Helyer of Sonic Objects; Sonic Architecture, Sydney;
Bec Dean, Curator at Performance Space, Sydney;
Jesse Olivieri, co-founder of Parachutes for Ladies in Sydney; and
Cigdem Aydemir, Vryfees visual artist for 2014.

“Given the histories and present experiences of human rights violations and racial discrimination that indigenous people in Australia and South Africa are subjected to, we are particularly honoured to have Lee-Ann (Buckskin) as a guest speaker,” said Prof Andre Keet, Director of the UFS Institute for Reconciliation and Social Justice.
