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.

UFS appoints new head for Research Commercialisation and Business Development

2009-02-27

The University of the Free State (UFS) has appointed Dr Glen Taylor (pictured) as the new head of the Office for Research Commercialisation and Business Development.

The purpose of this new office is to optimize the commercialization of innovation and intellectual property at the UFS.

According to Dr Taylor, the core function of this office is to establish a sustainable third stream of income from intellectual property in order to diversify the funding base of the University. In essence, the office is responsible for the facilitation of technology transfer.

Aside from the normal aspects associated with technology transfer, such as innovation disclosure, intellectual property protection (patenting) and licensing, a rather broader approach of transferring knowledge to a user in society will also be sought.

“It is evident that the funding environment has changed significantly due to a shift in priorities from public funded agencies, which have impacted hugely on tertiary education,” said Dr Taylor. “Furthermore, due to the changes in the state funding of universities, there is more pressure on these institutions to become financially self-sufficient.”

“So in the light of these challenges, universities as generators of knowledge have a fundamental role to play in the knowledge society, and through the process of innovation and intellectual property development there must be value to the institutions and the individuals.”

Dr Taylor is the former Head of the Department of Agricultural Management and manager of research, technology and innovation activities on the George Campus of the Nelson Mandela Metropolitan University.

The Office for Research Commercialisation and Business Development was established at the beginning of 2009.
