Abstract

Lighting is an essential service in all industries. Recent innovation and continuous improvement in the field of lighting has given rise to tremendous energy saving opportunities in this area. This paper presents the results of an energy audit carried out at an industrial site of a famous manufacturing/mining holding in Zimbabwe. It has been demonstrated in this spefici c case study that the improvement of lighting technologies can determine a reduction of electricity consumption more than 150 000kWh/year with an annual electricity cost saving of the order above $50 000 per year. The total simple payback time of the proposed lighting retrofitting is evaluated to be less than 2 years on average.
