Abstract

This study emphasized on the famous factors (activity, structure and intensity) responsible for energy consumed in the South African Construction and Building industry between 1994 and 2016. A famous technique in the understanding of such factors was employed – Logarithmic Mean Divisia Index (LMDI). Structure effect was inconsequential on its impact on the change in energy consumption. Intensity on the other hand played its role to affecting the energy consumption positively but could not overturn the increase experienced during the period of study. Activity effect was the major contributor to the 88.7% increase in the energy consumed. Improvement on energy efficiency within this industry requires not just investment on new technologies but improvement on existing technologies will improve the various activities/operations needed within the industry.
