Energy Auditing

An energy audit is an essential step towards identifying how much energy and related cost savings can be made across your business. The energy audit may be across a specific aspect of a building through to a campus wide audit.


As energy costs continue to increase, businesses are increasingly turning to energy use as a means to reducing their cost of doing business. WSP | Parsons Brinckerhoff with the specialist existing buildings energy management team, supported by established offices across all regions of Australia can undertake energy audit to the required level and deliver practical and sustainable energy savings to your organisation.

Typical energy audits that are required by our clients include:

  • Level 1, 2 or 3 consistent with AS/NZS 3598:2000
  • EEO (Energy Efficiency Opportunity) Program compliance assessments
  • Audits on the energy performance of specific systems or items of plant within a building or facility
  • NABERS Improvement Plans

Our audit teams focus on both operational as well as technological opportunities. Many energy audits undertaken by equipment suppliers focus on specific technologies and the need to spend capital, when often there is greater opportunities in improving controls and changing work practices.  We also employ digital technologies where appropriate to assist with the audit as well as track ongoing energy usage.

What the energy audit gives you

This will be clearly defined in the proposed scope of work, however typically the report will provide the following:

  • Brief summary of the installed energy using systems
  • Energy use summary and commentary on trends over the last 24 months
  • Key impacts on energy usage
  • Where energy is used (energy mass balance)
  • Identified opportunities with itemised energy, cost and carbon savings
  • Payback of individual and bundled projects
  • Recommended implementation strategy

Expected savings

Energy savings vary from project to project and depend on a range of factors such as the energy costs, the systems being assessed and the current energy management practices. Regardless, the savings are sure to significantly outweigh the audit cost. WSP | Parsons Brinckerhoff is focused on providing value for money for our clients and if, prior to the audit, we believe that there will not be sufficient savings to justify the cost, we will discuss this with you.

Our auditing teams have significant on site experience and ensure that there is full compliance with general OH&S procedures and work with each client to ensure site based procedures are understood and adhered to.
