Maximise and empower your business with an energy audit

More than an energy audit, a powerful way for the sustainable growth of your company

An Energy Audit is a review of how you use your energy and more importantly where it is being wasted. It is the first step towards energy management and energy cost savings. Non SME’s are legally obliged, under the EU Energy Efficiency Directive and SI 426 of 2014, to have an energy audit carried out by a registered auditor. 

Understanding Energy Audits for Businesses

What exactly is an Energy Audit?

A business energy audit is a comprehensive assessment of the energy consumption of a company or organisation with the aim of identifying opportunities for energy efficiency and savings. This assessment includes a review of the facilities, equipment, processes and energy consumption habits of the business.

What is the objective of the energy audit?

The objective of an energy audit is to help companies understand their energy consumption, detect areas of inefficiency and propose measures to reduce costs and improve environmental sustainability. 

What types of energy audits exist?

Walkthrough Audit

  • Light audit​

  • Brief inspection of facilities to identify maintenance operational, deficient equipment and areas for further evaluation

Comprehensive Audit

  • Thorough audit

  • Measuring & Monitoring

  • Detailed evaluation

  • Energy consuming systems

  • Economic evaluation

  • Identified opportunities

  • Cost and benefits

Benefits of the Energy Audit

Long-term planning

Long-term perspective for effective planning and budgeting.

Regulatory compliance

Compliance with regulations and avoidance of sanctions.

Cost reduction

Identifying and Reducing Unnecessary Energy Consumption

Improve competitiveness

Increased advantage and competitiveness in the industry by only paying for what is necessary.

Improvement of operational efficiency

Increased productivity and better resource use practices.

The audit effectively becomes the road map to energy reduction

Depending on the facility we would agree an energy reduction target for the next three years. Our objective would be to re-audit in four years time even though this is not a legal requirement for SME’s. The European Union (Energy Efficiency) Regulations 2014 (S.I. No. 426/2014) transpose into Irish law European Directive 2012/27/EU on Energy Efficiency.


Under the Regulations, all organisations which are not SMEs (i.e. enterprises which employ fewer than 250 employees and have an annual turnover not exceeding €50,000,000 or annual balance sheet total not exceeding €43,000,000) will either have to carry out an energy audit or have a certified energy or environmental management system in place.​

  • What is an energy management company and what does it do?
    An energy management company is a company in charge of providing services and solutions to improve energy efficiency and sustainability in buildings, industries or municipalities. Its goal is to optimise energy use and reduce costs through the implementation of technologies and measures that enable more efficient consumption. The activities and services that energy management companies can perform include: Energy audit: This consists of carrying out an exhaustive analysis of the energy installations and processes of a company or entity, in order to identify opportunities for improvement. Design and implementation of energy management systems: Responsible for developing and implementing a strategic plan for efficient energy management, setting clear objectives and targets and proposing measures and technologies to achieve them. Installation of measurement and monitoring systems: These systems allow real-time measurement of energy consumption and the detection of possible deviations or anomalies that may arise. Energy efficiency advice and consultancy: They guide companies on how to improve their energy efficiency and reduce their carbon footprint by adopting sustainable measures and technologies. Renewable energy implementation: Helping companies to integrate renewable energy sources into their processes, such as solar, wind or biomass, which helps to reduce their dependence on fossil fuels and reduce their greenhouse gas emissions. And much more
  • Why is it important to work with an energy management consulting?
    Working with an energy management company can be beneficial for a company for several reasons: Cost reduction: An energy management company will analyse and optimise a company's energy use, which can result in a significant reduction in energy costs. Improved energy efficiency: The energy management company will help identify and correct possible inefficiencies in energy use, which in turn will help reduce consumption and costs. Compliance with regulations and standards: The energy management company is also responsible for ensuring that the company complies with regulations and standards related to energy use, avoiding potential fines and penalties. Reducing environmental impact: By improving energy efficiency and using renewable energy sources, the company can also reduce its environmental impact and contribute to sustainability.
