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 forms International Advisory Council

2010-11-09

The University of the Free State (UFS) has established an International Advisory Council (IAC) to advise the leadership of the university on its future positioning strategies, especially in relation to its international ambitions as a place of scholarship and service among the leading universities in the world.

The Council, constituted by Prof. Jonathan Jansen, Rector and Vice-Chancellor of the UFS, consists of nine high-profile international experts with proven expertise, leadership, influence and experience.

“Since the appointment of Prof. Jansen, the leadership of the university has been revising and aligning several functions as part of a thrust to position the institution to meet 21st century national, regional and international challenges,” says Prof. Aldo Stroebel, Director of International Affairs at the UFS.

The appointment of the IAC is one of the strategies to advise and guide the UFS during the next phase of development and growth.

The university is fortunate to have attracted council members from various spheres of influence who can provide strategic guidance and bring cutting-edge expertise to bear on the policies, strategies and actions plans of the UFS. Among them are Prof. Brenda Gourley, former Vice-Chancellor of the University of Natal (now UKZN); Mr Gert Grobler, SA Ambassador to Japan; and Ms Phumzile Mlambo-Ncquka, Former Deputy-President of South Africa, and Executive Chairperson of the Umlambo Foundation.

The first meeting of the Council will take place from 10-13 November 2010. During this meeting the Council will advise the university leadership on the positioning of the UFS in a global knowledge economy; research excellence; excellence in the scholarship of teaching and learning; student engagement and transformation; and other strategic programmes of focus, including engaged scholarship.

The other Council members are:

- Prof. Joel Samoff: Professor of African Studies, Stanford University, USA (Chairperson)
- Prof Luc D’Haese: Chairperson: University International Committee and Advisor to the Rector, University of Antwerp, Belgium
- Prof. Masafumi Nagao: United Nations University and International Christian University, Japan
- Dr Uri Ofir: International Entrepreneur and Business Development Specialist, Scientech Inc., Switzerland
- Prof. Alice Pell: Vice-Provost International Affairs, Cornell University, USA
- Prof. Akilagpa Sawyerr: Former Secretary-General, Association of African Universities (AAU), Ghana
