What is an energy audit and why is it important?

An energy audit is a comprehensive procedure to check the efficiency and proper functioning of heating and air-conditioning systems and heating and air-conditioning systems. It is not only a legal requirement, but also a key step in energy saving, safety and environmental protection. It helps to identify system weaknesses, optimise operation and reduce operating costs in the long term.

 

Why is an energy audit mandatory?

The mandatory nature of the review is laid down in the current regulations. Its primary aim is to increase energy efficiency and reduce carbon emissions in buildings. Regular inspections ensure that equipment is operating as optimally as possible, avoiding unnecessary energy losses and environmental impact. The changes, which will come into force from 1 January 2022, will place particular emphasis on the review of heating and air conditioning systems, which can be significant energy consumers.

 

Which equipment is affected and how often is an inspection necessary?

The energy audit covers heating and air-conditioning systems, but with different performance limits and frequencies. It is important to be aware of which equipment is affected by the regulation and when the inspection is due.

 

Review of heating systems

Energy audits of heating systems are mandatory in buildings where the rated output of the heating system exceeds 20 kW. The frequency depends on the output:

• For rated power between 20 kW and 100 kW: The inspection must be carried out at least every 10 years.
• For rated power above 100 kW: The inspection must be carried out at least every 5 years.

This inspection includes checking the efficiency and operation of heat generating equipment such as boilers, heat pumps and other heating sources.

 

Review of air conditioning and air conditioning systems

An air conditioner inspection is mandatory above the following performance limits:

• For rated power between 12 kW and 100 kW: The inspection must be carried out at least every 10 years.
• For rated power above 100 kW: The inspection must be carried out at least every 5 years.

This includes individual air conditioning systems, central air conditioning systems and all refrigeration equipment in the building.

Who can carry out the energy audit?

The energy audit can only be carried out by an accredited expert who is authorised to do so in accordance with the regulations in force. The expert must be duly licensed and qualified to carry out the inspection properly and professionally. It is important to choose a reliable and experienced professional who can guarantee accurate and relevant results.

 

What happens during the review? The step-by-step process

The energy review is a structured process consisting of several steps. Here is what you can expect during the review:

1. Preparation and data reconciliation: the expert contacts the operator and arranges a date for the review. At this time, basic data such as equipment type, performance, age and previous maintenance records are obtained.
2. On-site inspection and measurements: the expert will assess the equipment on site, visually inspect its condition and take instrumental measurements (e.g. temperature, pressure, flow). The purpose of the measurements is to determine the current performance and efficiency of the system.
3. Data collection and analysis of documentation: the expert collects operational data such as energy consumption patterns, maintenance logs and possible past failures. This data will help to better understand the system’s operation.
4. Analysis and evaluation: based on the data collected, the expert will analyse the energy efficiency of the system. This includes the identification of heat losses, excess energy consumption and possible faults in the system.
5. Developing recommendations: based on the results of the analysis, the expert will make recommendations to optimise the system, improve energy efficiency and reduce operating costs. These recommendations can be technical interventions, operational changes or even equipment replacement.
6. Record keeping: the results of the review are recorded in a formal report by the expert. This record confirms that the review has taken place and includes the detailed findings and recommendations.

 

What are the consequences of failing to review?

Failure to carry out an energy audit can have serious consequences. The operator may be fined if the legal requirements are not met. The level of the fine can depend on a number of factors and can impose a significant financial burden on the owner. In addition, an uncontrolled, inefficient system generates higher long-term operating costs, increases the risk of breakdowns and causes environmental damage.

 

Frequently Asked Questions about the Energy Review

 

How long is the energy audit protocol valid?

The validity of the protocol is either 5 or 10 years, depending on the type and performance of the equipment. For the exact validity period, see the section above “Which equipment is concerned and how often should it be reviewed?”.

 

What documents are required for the review?

In general, technical documentation on the equipment (e.g. type, performance, date of commissioning), previous maintenance logs and any previous inspection records are needed.

 

How much does the energy audit cost?

The cost of an energy audit depends on a number of factors, such as the number and type of equipment, the size of the building and the complexity of the audit. You can get an accurate quote by requesting a quotation.

Energy audits are essential for the long-term, efficient and safe operation of heating and air conditioning systems. The regulation, which will come into force on 1 January 2022, will pay particular attention to energy efficiency and sustainability. Regular checks not only ensure legal compliance, but also help to reduce operating costs and minimise environmental impact. Remember, failure to inspect can result in fines and, in the long run, significant financial losses.
