Energy Audits.

Energy audits are the essential first step for organisations to identify key areas for improvement. An Energy Audit entails a comprehensive analysis of a facility’s energy consumption, designed to identify areas for improvement and unlock cost savings otherwise unlikely to be realised.

What is an Energy Audit?

At its core, an Energy Audit involves a systematic evaluation of energy use, conducted by qualified audit professionals to an Australian standard. 

An Energy Audit can clarify your company’s energy consumption and identify areas for potential savings, as well as lead to reduced energy use, improved productivity and opportunities to innovate.

Typical Energy Audits include comprehensive analysis and reporting of a site’s energy usage across three categories aligned to AS NZS 3598.1 & AS NZS 3598.2, including: 

  • Detailed Tariff Analysis 
  • Time of Use (ToU) Analysis 
  • Energy Usage Breakdowns (EUBs) of all main energy-using equipment 
  • Energy Efficiency Opportunities, categorised by a payback period of less than 2 years or greater than 2 years
  • Detailed Asset Registry

Energy Assessments.

Energy Assessments are similar to Energy Audits, but are more high-level and primarily focused on finding the ‘low-hanging fruit’ relating to energy efficiency opportunities within a facility.

The Energy Assessment is a process where ‘quick wins’ are identified to reduce your energy consumption based on the findings of a site visit. The Return on Investment (ROI) of each Energy Upgrade is estimated based on high-level values and industry averages. 

Ecovantage’s specialists can help with both Energy Assessments and Energy Audits, and support you in determining which is the best option for your business.

The Outcome.

The advantages of Energy Audits extend beyond immediate cost savings. They provide valuable data that supports:

Informed Decision-making
Audits equip organisations with insights to make informed investment decisions about energy upgrades and process modifications.

Continuous Improvement
Regular audits create a tangible measurement of site progress while informing ongoing efforts.

Energy Audit Findings.

Below are some typical energy audit findings for different building types, including costs, savings and payback. Note that opportunities, costs, and savings may vary depending on specific site conditions.

Typical energy reduction opportunities identified at a retirement living facility.

Opportunity Capital Outlay Annual Energy Savings Simple Payback
Pool pump optimisation $3,000 10,000 kWh 1.2 years
Pool heating optimisation $5,000 6,500 kWh 3.1 years
HVAC temperature optimisation $6,000 7,300 kWh 3.3 years
Lighting upgrades (LEDs, sensors, etc.) $16,000 17,000 kWh 3.8 years
Install solar PV $150,000 150,000 kWh 4.0 years
Replace gas-fired hot water with heat pumps $35,000 320 GJ 9.1 years

 

Typical energy reduction opportunities identified at hotels and motels.

Opportunity Capital Outlay Annual Energy Savings Simple Payback
Pool heating optimisation $5,000 500 GJ 0.8 years
Pool pump optimisation $3,000 10,000 kWh 1.2 years
HVAC temperature optimisation $6,000 7,300 kWh 3.3 years
Lighting upgrades (LEDs, sensors, etc.) $16,000 17,000 kWh 3.8 years
Install solar PV $750,000 70,000 kWh 4.5 years

 

Typical energy reduction opportunities identified at golf course clubhouses.

Opportunity Capital Outlay Annual Energy Savings Simple Payback
HVAC temperature optimisation $15,000 20,000 kWh 3.0 years
Install solar PV $150,000 150,000 kWh 4.0 years
Lighting upgrades (LEDs, sensors, etc.) $20,000 15,000 kWh 5.3 years

 

Notes:
Used an average electricity rate of $0.25/kWh and natural gas rate of $12.00/GJ
Savings associated with pools are based on a pool located in Victoria, running 24 hrs/7 days, setpoint of 28°C

Specialist Support.

Our national in-house Measurement & Verification team who undertake the Energy Audits are highly regarded within the industry. The team is made up of Mechanical, Electrical, and Energy Engineers with extensive experience across complex Energy Audits, large-scale energy project implementation and significant experience operating within Australian federal and state energy schemes. 

Ecovantage’s Energy & Carbon Services team also has the knowledge and expertise to outline any opportunities for Federal and state-based white certificate rebates available with each Energy Efficiency Opportunity identified and recommended. This ensures the payback period is minimised as much as possible, and the recommendations are action-oriented.
