During discussions about the natural environment and energy saving, the term energy certificate often comes up. What is it and what does it mean for owners and users of residential or commercial properties? Read the article from the experts at TERMOFOL and find out when an energy certificate is required.
What Is an Energy Certificate?
Currently, energy efficiency is one of the main criteria for assessing real estate. Understanding the significance of this document is essential, especially in light of the regulations and standards in force today. The energy performance certificate is not just a formality, but an important aspect influencing purchasing and investment decisions.
Energy Certificate – What Is It? A Brief Definition
An energy certificate, also known as an energy performance certificate, is a document that specifies the energy efficiency of a building or its individual parts. It contains information about energy demand, which allows for the assessment of the required amount of energy for heating, ventilation, or hot water preparation, depending on the standard of the property and its insulation.
What Does an Energy Certificate Look Like?
The basic elements of an energy certificate are:
- Energy rating – classification of the building on a scale from A+ (very energy-efficient) to G (very inefficient), which facilitates the comparison of energy efficiency between different properties.
- Data on energy consumption – information about the average annual energy consumption for needs.
- Recommendations for improving energy efficiency – advice on how to reduce energy consumption, for example, through the modernization of heating systems, improving insulation, or installing solar panels.
Detailed conditions for the energy certificate can be found on the website of the Ministry of Development and Technology.
When Is an Energy Certificate Required?
This document is essential for any sale or rental transaction of a house or apartment, highlighting its universality and importance in the real estate market. This ensures that both sellers and buyers have a clear picture of the energy efficiency of a given property, which directly impacts purchasing decisions and planning for future maintenance costs.
Energy Certificate for Older Buildings – Why Is It Important?
Many older structures do not meet current energy efficiency standards, making them often expensive to maintain. According to current regulations, the energy certificate for older buildings is just as important as for new constructions. This requirement emphasizes the need for modernization and adaptation of existing properties to new standards. This is particularly significant in the context of protecting architectural heritage and adapting living spaces to modern ecological requirements. With the energy certificate, owners of such buildings can obtain a specific action plan aimed at modernizing them to meet contemporary requirements. In the long run, this brings significant savings and increases the property's value on the market.
The energy certificate is therefore not just a collection of dry data, but primarily a tool that enables the assessment and comparison of a property in terms of energy efficiency. Its importance grows with the emphasis on sustainable development, ecology, and savings, becoming an integral part of the modern real estate market.
For this reason, both private individuals and professionals in the industry should have knowledge about how the energy certificate is prepared, what information it contains, and what its significance is for the assessment or value of the property.

Thanks to this characteristic, owners can make informed decisions regarding investments in technologies that reduce energy consumption, which translates into lower costs and improved user comfort. Where to obtain an energy certificate? How long is it valid?
Who Prepares the Energy Performance Certificate?
This task falls to qualified energy auditors, who, thanks to their knowledge and experience, can accurately assess a building's energy efficiency. These auditors use advanced technologies and methods to make precise measurements and analyses.
How Long Is the Energy Performance Certificate Valid?
Knowing the validity period of this document is crucial for planning future modernization actions and potential sale or rental of the property. The validity of the energy certificate is typically set at 10 years.
Where to Obtain an Energy Certificate?
The answer to this question leads to a network of qualified specialists and auditing firms that offer their services in the field of energy assessment and certification. Choosing the right auditor, who has experience working with both new and old buildings, is a decision that can have a long-term impact on the property's value.
