Abstract
The electrical supply utility, ESKOM, cannot cope with the growing demand in South
Africa. This results in load shedding and power outages. This capacity can be
augmented, by conducting energy audits, retrofitting government buildings, designing
and installing cost-effective lighting systems, and using renewable energy sources in
rural areas. Households in rural areas depend on candles and paraffin lamps to
supply light at night. Solar panels as renewable energy sources are very expensive in
conventional lighting systems. The problem is that a cost-effective, affordable lighting
system has not yet been designed. The following four projects have been completed
by the author:
- Software development for a lighting design in general
- Efficient high bright light emitting diode (HB-LED) lighting system
- Energy audit and retrofit of the Nuwe Hoop School in Worcester
- Optimization of hybrid solar-diesel system
Firstly, the author wrote a program that is used in lighting designs. This illumination
software is utilized for educational purposes. A manual step-by-step lighting design
procedure was compiled. The JAVA object-oriented programming language was
used to write the code of the design software. Real life design parameters are fed to
the program, to confirm proper implementation. The software package will perform
illuminance calculations to display relevant Isolux diagrams for educational purposes.
