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.

Unconditional accreditation for Architecture at the UFS

2008-08-20

The Department of Architecture at the University of the Free State (UFS) is so far the only department of its kind in the country to obtain unconditional accreditation from the South African Council for the Architecture Profession (SACAP) for all three its programmes.

“SACAP has already visited seven out of a possible ten institutions in the country who present Architecture. Of these, only the UFS’s Department of Architecture has so far received unconditional accreditation. This is indeed an achievement for us,” said Prof. Jan Smit, Head of the Department.

According to Prof. Smit, the SACAP’s evaluation of all institutions who offer Architecture takes place every four years. During the accreditation process in 2004, the department also received unconditional accreditation for the two programmes it presented at that stage, namely the B.A.S. degree and the B.Arch. degree. Since then, the B.Arch. degree has fallen away and the qualifications the department now offers are the B.A.S. degree, B.A.S. (Hons.) and the M.Arch.(Prof.).

“The unconditional accreditation serves as proof that the qualifications obtained by our students are of value and that it enjoys local and international recognition. It is also an indication that our students’ training is up to standard,” said Prof. Smit.

The criteria students are evaluated on includes the facilities, degrees and courses presented, the standard of exam papers and assignments of a subject, the style of management and staff compilation. The panel of judges comprise of among others a representative from the Commonwealth Association of Architects (CAA), who reports to the Royal Institute of British Architects (RIBA). “This is an indication of the high level on which the evaluation is being done,” said Prof. Smit.
