Measuring up: the importance of energy audits in business

Historically, auditing has been seen as an undesirable expense with little perceived value for businesses. With organisations failing to see the benefit of examining the finer details of their operations, and with staff assigned to prepare for the audit feeling like they've drawn the short straw, audits have never been fun.

Until now. This is when energy audits enter the room to great fanfare. The shift towards sustainability, driven by environmental, social, and governance (ESG) factors, is reshaping how businesses approach energy consumption, waste management, and carbon footprint, and crucially, their relationship with audits.

Energy audits are the one type of audit that delivers positivity; they are one of the most effective tools to help businesses reduce their environmental impact while boosting their bottom line through optimised processes and reducing costs. For organisations across Aotearoa New Zealand, Australia, and the Pacific, understanding the significance of energy audits and how they lead to long-term cost savings, improved efficiency, and enhanced sustainability is fundamental to business success.

Unpacking energy audits: the key to unlocking sustainability

An energy audit is a comprehensive evaluation of a business's energy use and efficiency. Its primary goal is to uncover areas where energy is being wasted and identify opportunities for energy savings. This process is essential for any business aiming to improve its sustainability, reduce operating costs, and meet carbon reduction targets.

Whether you are operating a small enterprise or managing a large industrial site, an energy audit provides actionable insights to reduce the environmental impact of the business and improve energy management.

There are different types of energy audits, from Lite Audits offering a quick, low-risk assessment, to Detailed Energy Audits, which provide a more thorough and long-term analysis of energy use across the facilities. Both types of audits help you understand current energy consumption patterns and reveal the potential areas for energy efficiency improvements.

From insight to action: why energy audits are a business game-changer

Energy audits are not just about identifying problems; they are about identifying opportunities for improvement. By performing regular energy audits, businesses can benefit in the following ways:

Cost savings

One of the most immediate, attractive and tangible benefits of an energy audit is the potential for significant cost savings through the identification of inefficiencies that are costing the business or organisation money. For example, a company may be using outdated lighting or HVAC systems that consume excessive energy. Through equipment upgrades and optimisations, these inefficiencies can be corrected, leading to significant savings on utility bills. Energy audits are also adept at identifying unexpected bottlenecks in industrial processes and are often the first to highlight the potential for process optimisation, improving a business’s overall efficiency and profitability.



Carbon footprint reduction

Businesses around the globe are increasingly being held accountable for their carbon footprints. In response, many organisations commit to ambitious decarbonisation goals, such as reducing emissions by a set percentage over the coming years. Energy audits play a pivotal role in this process by identifying energy management opportunities to run a more sustainable operation, supporting a business’s overall carbon reduction management strategy.

Regulatory compliance

In Aotearoa New Zealand, Australia, and the Pacific regions, governments are implementing stricter regulations around energy consumption, carbon emissions, and sustainability. Businesses need to stay ahead of these regulations to avoid potential fines or reputational damage. Energy audits ensure they comply with environmental laws and policies and demonstrate their commitment to sustainability.

Improved operational efficiency

Beyond energy savings, energy audits offer a chance to improve the overall efficiency of a business’s operations. Through detailed assessments of energy usage, businesses can uncover opportunities for more efficient practices that extend beyond energy management. For example, improvements in water usage, wastewater management, and waste reduction practices can complement the findings from an energy audit, helping businesses operate more efficiently across the board.

Enhanced ESG performance

Businesses and organisations are under huge pressure to demonstrate their commitment to sustainability. Energy audits provide an essential part of the evidence needed to document meaningful progress towards sustainability goals. Energy audits are often recommended by ESG consultants as part of a broader sustainability strategy to improve a company’s environmental performance to enhance their ESG ratings. This is highly appealing to environmentally-conscious investors and stakeholders, helping to build a stronger brand reputation.

The energy audit process: a step-by-step guide

An energy audit typically involves several steps, depending on the level of detail required and the scale of the business. For a comprehensive energy audit, businesses can expect the following process:

1.   Site inspection and data collection

Energy consultants conduct site visits to assess the energy usage patterns across the business. This includes collecting data on current energy consumption, examining equipment and infrastructure, and speaking with key stakeholders to understand the reality of operational needs and goals.

2.   Energy and carbon reduction opportunity review

Consultants collate and analyse the collected data and review any existing energy management practices. This enables opportunities for energy optimisation to be identified, such as more efficient lighting, upgraded HVAC systems, or updating manufacturing processes. Carbon reduction opportunities may include switching to renewable energy sources or implementing waste-to-energy technologies.

3.   Return on Investment (ROI) analysis

A key component of any energy audit is calculating the potential return on investment (ROI) for the proposed changes. Consultants provide businesses with detailed financial analyses, helping them understand the potential savings and payback periods for energy efficiency projects.

4.   Reporting and recommendations

Once the audit is complete, energy efficiency consultants deliver a comprehensive report detailing their findings. This report outlines the energy and carbon reduction opportunities, prioritises high-return actions, and provides clear recommendations for how to implement the recommended changes effectively and within budget.

5.   Implementation and monitoring

After recommendations are made, DETA’s energy consultants assist with implementing energy-saving measures. This may include overseeing installations, managing contractor relationships and supplying funding support assessments; clients decide the level of industrial project management they require to support the transition. Ongoing data monitoring ensures the success of the energy management plan.
