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.

FASSET funding bid secures R54 million for black accounting students

2015-08-28

The Centre for Accounting in the Faculty of Economic and Management Sciences has made great strides with its INTRABAS projects, which support the development of black student enrolment and performance in Accounting Studies.

Recently, the university won four bids that have secured R54 million in funding from the Finance and Accounting Services Sector Education and Training Authority (FASSET) for 2016. This funding will support the teaching and learning initiatives of 960 black accounting students enrolling for the following four accounting programmes: BAcc, BCom(Acc), BAcc(Hons)/PGDipCA and BCom(Hons in Acc)/PGDipGA.The benefit to these students is the envisaged increase in throughput rates by 10% from year- to- year until the Honours year. This covers tuition fees, text books, and extra tutorials, including autumn, winter and spring boot camps.

“FASSET funding will give the Centre for Accounting an opportunity to strengthen our current student-centered teaching model” said Prof Hentie van Wyk, Programme Director: Training of Accountants at the UFS.

The Centre for Accounting has a “1” accreditation grading from the South African Institute of Chartered Accountants (SAICA), and has achieved an 80% average success rate over the past three years in the Initial Test of Competency (ITC) of SAICA.

Download the application form for FASSET funding or collect one at the Centre for Accounting at the Faculty of Economic and Management Sciences. The closing date for applications is 31 October 2015.
