Technology Collaboration Programme

April 2015 Workshop – International Conference: Domestic Use of Energy, Cape Town, South Africa

Welcome to the 23rd International Conference on the “Domestic Use of Energy” (DUE). We know that the world and especially South Africa is challenged to find sustainable solutions to energy provision and energy must be used wisely, so it is essential that we research and find lasting solutions for the effective use of energy in the home. The theme of the conference “Domestic Use of Energy” resonates very well with CPUTs goal of environmental sustainability and efficiency.
