Energy Efficiency Technician

South Africa remains highly dependent on coal fired electrical power, despite its commitment to the Paris Agreement and reducing greenhouse gases to net zero by 2050. The exploration of cleaner renewable energy options will support a transition to a carbon neutral economy with decreasing reliance on coal fired electricity and its environmental and health impacts. Energy efficiency involves the adaptative measures and technologies used to reduce energy consumption.

Energy efficiency technicians evaluate electrical installations, equipment and processes to determine the amount of energy used and lost to improve energy usage and recommend and install energy conserving measures. They audit the ventilation, heating and cooling, lighting and power systems during building construction and at manufacturing plants. Some can be consulted to provide energy usage goals for businesses and analyse costs and benefits of energy saving devices.

Energy efficiency technicians work alongside electrical engineers and technicians as well as building owners and managers. They often work in an office environment and travel to conduct site inspections of homes, businesses and industrial environments to determine causes of energy wastage and make recommendations for efficient use.


Energy efficiency technicians require a technical knowledge of energy saving technologies and electrical equipment and an understanding of energy efficiency compliance regulations. They will further benefit from:

  • Methodological problem-solving skills
  • Ability to read and interpret building plans and schematics
  • Ability to use design and energy modelling software
  • Good verbal and written communication skills
