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.

Odeion School of Music launches new Organ Chair

2015-09-16

Liesbeth Schlumberger-Kurpershoek

The Odeion School of Music (OSM) at the University of the Free State (UFS) has become the first in the country to launch an Organ Chair, named after seasoned international organist Liesbeth Schlumberger-Kurpershoek.

Over the last two decades South African has seen a decline in organ student numbers. The School of Music has taken the initiative by deploying experts and instructors to coach and mentor OSM students, in an effort to increase their chances of excelling in the international music scene.

The Organ Chair is an entity of the International Artistic Mentorship Programme (IAMP), which aims to establish partnerships between successful international musicians and OSM students. It is within this context that the OSM decided to launch the institutionalisation of an Organ Chair in a programme scheduled to take place from 8 -13 September 2015 in the Bloemfontein Campus and in surrounding areas.

Meet the expert

Liesbeth Schlumberger-Kurpershoek is a French-South African organist and pedagogue, who is well versed in the music profession. This bodes well for our university’s music students. Initially educated by the great Stephanus Zondagh at the University of Pretoria while still a school pupil, Liesbeth’s passion for music has soared to great height since then.

Some of her accolades include winning the prestigious SABC Music Prize in 1985, and the International Organ Competition held in Bordeaux in 1989.

Liesbeth has worked with distinguished organists at the France Conservatoire National de Ruiel-Malmaison, the Conservatoire National de Région, Conservatoire National Supérieur de Musique in Lyon, and is the organist at Reformed Church of Etoile in Paris. In 2010, she was an adjudicator at the Chartres International Organ Competition, one of the most prestigious of its kind in the organ world.

This active recitalist and masterclass pedagogue facilitated classes attended by master students from Cape Town, Stellenbosch, and Potchestroom, and workshops as part of launching the Liesbeth Schlumberger-Kurpershoek OSM Organ Chair.
