When Mustek, South Africa’s largest assembler and distributor of personal computers, integrated an energy management system (EnMS) in 2015/16, the company implemented ten projects at a total capital investment of R148 000. The implementation resulted in monetary savings of R243 000 and electrical energy savings of 243 MWh, which constitutes a 15% reduction. As a company with ISO 9001, 14001 and 2000 certification, Mustek proved the effective it can be to integrate the principles of energy management into already existing business systems.
In February 2015 Mustek Ltd successfully integrated an ISO50001-aligned Energy Management System (EnMS) into their already existing Business Management System (BMS). They were able to do this by gaining the trust of their employees and involving them in the planning and implementation of the EnMS project. By so doing, Mustek Ltd aligned its innovation processes with those of energy management and conservation.
