Energy/carbon auditors may do some or all of the following:

  • inspect buildings and carry out energy surveys/audits
  • ensure accurate records are kept and energy monitoring data is collected regularly
  • develop methods to reduce energy use at businesses and organisations, and help put these methods into practice
  • set up procedures to monitor and assess carbon emissions
  • develop methods to reduce carbon emissions
  • review the effectiveness of energy and carbon reduction measures and verify any savings made from these changes
  • write reports and present findings to clients
  • provide technical and practical advice, and offer training on energy efficiency
  • provide technical support to mechanical and electrical design engineers.

Useful Experience

Useful experience for energy/carbon auditors includes:
