Systems optimisation

Cost effective savings are often possible by making better use of existing plant and equipment. By recalibrating equipment so that it meets the needs of building occupants and production demands, significant energy savings can be achieved.

What's on offer

EECA’s systems optimisation programme can be utilised by commercial and industrial sites whose energy systems energy spend totals at least $150,000 per year.

EECA’s Programme Partners can assist in optimising the performance of the following types of systems:

  •     HVAC systems
  •     Lighting systems
  •     BMS systems
  •     Process heat (boilers, furnaces, steam and hot water systems)
  •     Compressed air systems
  •     Refrigeration systems
  •     Pumps and motors


These systems can be significant energy users across both industrial and commercial sectors. Systems optimisation focuses on tuning and recalibrating existing equipment, as opposed to purchasing new equipment. EECA can contribute to the cost of specialists that will undertake such tuning.

In some instances significant gains can be achieved by adding additional sensors and feedback systems (e.g. display panels or dashboards) to existing control systems. EECA is able to support such activities provided they deliver sufficient savings. The Systems optimisation programme cannot be used to purchase/replace control systems e.g, lighting control systems or building management systems.

Boiler tuning

For every dollar you spend on tuning your boiler, you can save up to $30 on your energy bill. We can help with the cost of introducing and locking-in a 6-monthly boiler tuning schedule.

For greatest savings, boilers should be tuned at least every 6 months. Many businesses have annual maintenance programmes, but only tune boilers once a year. Good tuning adjusts the boiler’s air-to-fuel ratio to get maximum fuel efficiency. It’s a simple process that takes a couple of hours and can cut up to 25% from your energy bill.

Knowing whether your existing system is running efficiently is a key energy management principle and there is little value in tweaking a system that operates near its peak performance. To get the best value from the Systems Optimisation programme it may be best to utilise some of the following options first:

  • Energy Audits – to benchmark site/system efficiency
  • Monitoring & Targeting – to measure existing energy performance for a site/system   and measure the improvement
  • Design Advice Programme:    
    • 2c: Commissioning buildings
    • 2d: Post-occupancy review


- Improved thermal comfort
- Reduced maintenance
- Greater visibility of energy use (sometimes)

EECA may fund up to 40% of the cost of optimising a system, up to a maximum of $100,000.

For boiler tuning, EECA funding can cover up to 40% of the costs of each 6-monthly boiler tune-up. We’ll fund up to $5,000 a year per site for tuning boilers, which can be solid, liquid or gas fuelled. You’ll also get a savings report and suggestions on how to be more efficient. You must commit to 6-monthly tunings over a 2-year period.

Who should apply

Your site must have energy systems using a minimum total of $150,000 of energy per year.


To qualify, your project must deliver a guaranteed level of energy savings. Our funding is usually enough to ensure the project meets your investment criteria.

Generally, EECA doesn’t fund projects with a payback of less than 2 years, as we expect businesses to fund these themselves. EECA funding is aimed at getting cost-effective projects over the line without over-funding.

How to apply

Our experienced Programme Partners will advise you about funding, the best system for your building and help you to install and run it.
