Australian large retail venues like shopping centres, retail malls and large box stores use enormous amounts of energy mostly for HVAC, lighting and refrigeration.

Fortunately, we now have a wide range of technologies to make these sites much more energy efficient. Cost savings of 70% for lighting, 30-50% for air conditioning and refrigeration are achievable. The typically large and unshaded roof space lends itself to the installation of solar power.

Further cost savings can be achieved by addressing kVA or kW demand based billing issues:

• Power Factor correction
• Using solar power and / or small battery systems to reduce daytime demand peaks
• Variable speed drives for large motors (e.g. large aircon compressors)

A comprehensive level 2 or 3 energy audit will identify the technologies and show cost & benefits of any technology retrofit as well as evaluate solar power options.

Powersmart audits can be custom-tailored to achieve maximum cost savings at minimum costs:

• Power-monitoring / Data logging / Load profiling
• Lighting audit only (with attention to ESS certificate eligibility)
• Large HVAC only (chillers, packaged units – attention to use of Smart Energy technology)
• Refrigeration only (large supermarkets)
• Renewable energy (solar power, peak demand shaving with Solar power and batteries)
• Power factor correction
  

The cost of our services range from as low as $3,000 for a full lighting audit to $12,000 for a level 2 audit covering all aspects of operation as outlined above.
