ENERGY MANAGEMENT SYSTEM: THE BEST TOOL FOR ENERGY MANAGEMENT IN THE POSTAL SECTOR

ISO 50001:2011-  Energy Management System (EnMS) was developed to specify requirements for establishing, implementing, maintaining and improving energy management systems with the purpose to enable organizations to follow a systematic approach in achieving continual improvement on energy efficiency, energy use and energy consumption.The paper will focus on testing two hypotheses which are as follows: Hypothesis 1-  Energy Management System is the best tool for energy management in the postal services. Hypotheses 2- Energy Management System is not the best tool for energy management in the postal services. The hypotheses will be tested by assessing the current energy management for mail centres and fleet in the South African Post Office as a benchmark, and comparing it to the projected outcomes of implementing the ISO 50001:2011-EnMS.Historical energy (electricity and fuel) data will be analysed to establish the baseline, the significant energy users and drivers will be derived from the current operations and also be used to determine the suitability of the system to operations. The outcomes of the data analysis will determine the final result of the two test hypothesis.
