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.

New Academic Head at South Campus to expand distance learning programmes into the global arena

2016-02-10

“Critical area of focus: Diversify provision, based on open learning principles, to improve learning opportunities across the post-school education and training sector” - SA Department of Higher Education and Training Strategic Plan 2015/16-2019/20

Open and distance learning (ODL) programmes will play a critical role in shaping the landscape of higher education. Not only does the South African Department of Higher Education and Training emphasise the importance of ODL, it is also contained within the United Nations’ Sustainable Development Goals. And now the University of the Free State (UFS) is becoming a major role player in the field through the cutting-edge ODL programmes offered by the South Campus.

Jean Grundling has recently been appointed as the Academic Head of the South Campus.

At the helm of these programmes is the recently-appointed Academic Head of the South Campus: Jean Grundling. According to the new organisational structure of the South Campus, the Academic Head reports directly to the Campus Principal: Dr Daniella Coetzee.

“My role,” says Grundling, “focuses on developing and monitoring processes that will enable effective and efficient implementation of the three pillars of ODL.” These three pillars consist of:

• the design and development of quality learner-centred learning materials and tools during their ODL journeys;
• the selection, appointment, and development of competent facilitators to guide, coach, tutor, and support students; and
• the integration of administrative processes that will enable and support students to study at their own pace, place, and in their own time.

“Goal 4: Ensure inclusive and equitable quality education, and promote lifelong learning opportunities for all.”
United Nations Sustainable Development Goals

As part of her personal vision, Grundling would like to see the South Campus grow and develop into an institution that offers quality ODL programmes not only nationally, but globally. “I would like the South Campus to become an agent of social transformation in South Africa.”

Ultimately, Grundling’s wish is for the South Campus to contribute to the development and empowerment of people so that they can play a positive role in society.
