  • Identify sources of energy to the site, the amount of energy supplied, and what the energy is used for Identify areas where savings may be made
  • Recommend measures to be taken, and provide a statement of costs and potential savings


SLR undertook the following works:


SLR’s Environmental Sustainable Development (ESD) team undertook Level 2 Energy and Lighting Audits and related deliverables consistent with AS/NZS 3598 for the nominated facilities.


SLR carried out a review of energy tariffs relevant to the sites of interest.


On the basis of the above inputs, SLR put forward recommendations for improvements in energy consumption including the required capital investment, projected savings and payback periods.

The tariff-related recommendations led to savings in the first year post-study of over $30k.
