What is an energy audit?
An energy audit or energy scan is a systematic assessment of how energy is used, stored and re-used within an industrial facility. The goal of this is to uncover inefficiencies and propose and implement measures to reduce industrial energy consumption while at the same time reducing emissions. This audit reveals opportunities, such as waste heat recovery, improved equipment performance and optimized energy usage.
Why conduct an energy audit?
With increasing pressure to reduce emissions and cut costs (due to inflation), an industrial energy audit is no longer optional, it’s strategic. Optimizing your site’s energy usage improves process efficiency and helps align with environmental regulations, including emission limits.

Benefits of an energy audit
Combining environmental and financial imperatives
Our industrial energy audit is a bridge between sustainability goals and financial performance, which enhances energy efficiency, reduces environmental impact and unlocks long-term savings.
Comply with EED audit guidelines
The Energy Efficiency Directive promotes energy efficiency within the EU. Our audits help you take control over your heat sources, energy use and emission limits, contributing to your compliance with EED energy audit guidelines (Directive 2012/27/EU).
Increasing operational efficiency and match with emission limit reduction
Directly contribute to global climate goals. By optimizing energy use, reducing resource waste, and integrating cleaner technologies, industries can significantly reduce their environmental footprint while maintaining or even boosting productivity.
How JOA conducts an Energy Audit for you
At JOA, we take a fully actionable approach, including the following:
Analysis: Our team analyses your site’s energy consumption, evaluates process heat losses and highlights opportunities for waste heat recovery.
Report: We deliver a detailed report with actionable recommendations, prioritized by financial return and impact on emissions.
Why choose JOA?
JOA designs, builds and implements tailor-made systems for dust collection, scrubbers and energy recovery, optimizing industrial performance and sustainability. We always start by diving deep into your challenge with a Pre-Engineering Study or Energy Audit in advance. Choose JOA to ensure your industrial energy audit translates into impact.
Energy Audit FAQ
An energy audit focusses on how energy is used and identifies inefficiencies and waste. In contrast, a carbon audit evaluates your greenhouse gas emissions. While both audits are related, they serve different purposes. Combining both provides a clear picture of your facility’s footprint.
As we only focus on the Energy possibilities, the costs are generally lower than an extensive Pre-Engineering Study. Still, it depends on the complexity of the situation and the location of the site. In general an Energy Audit in Western Europe would cost about €12-15k. We would love to show our worth and prove the value of our expertise so we often provide additional conditions when an Energy Audit leads to a heat recovery system.
EED stands for Energy Efficiency Directive. This is a European directive aimed at promoting energy efficiency across EU member states. It sets out legal requirements and audit obligations, especially for larger industrial and commercial energy users. It’s set up to reduce overall energy consumption and support the EU’s climate and sustainability objectives. Compliance may require periodic energy audits and the adoption of energy management systems for industrial organizations.
JOA uses it’s own ‘Energy Audit Checklist’. In this checklist, our engineers check all opportunities where we can recover heat from. These may be called Heat Suppliers. This may be process streams, exhaust gasses, dust collection systems or scrubbers. Next to that, we identify heat sinks or consumers. Heating the offices and production site is dependent on the location and season. Process heat or steam, just like drying processes are good consumers. Lately, we also see more requests of industrial players combining heat demands from surrounding neighbourhoods like heating networks.
