Energy certificate


Energy performance certificate explained clearly:

Optimize the efficiency of your property

An energy performance certificate is mandatory for property sellers and new tenants. The basis for this is the Building Energy Act (GEG), which has replaced the Energy Saving Ordinance (EnEV).

Our approach

Our process begins with an inspection and assessment of your property. We analyze every aspect, from the insulation to the heating, to obtain an assessment of the characteristic values. We then create an energy performance certificate that presents this information.

There are two main types of energy performance certificate: the demand certificate and the consumption certificate.


The demand certificate is based on a technical analysis of the building and its components, including insulation, heating system and window quality. It indicates how much energy the building should consume under standardized conditions.


On the other hand, the consumption certificate is based on the actual energy consumption of the last three years.


The evaluation depends heavily on the habits of the users. The energy performance certificate classifies the theoretical DIN-compliant energy efficiency of the building on a scale from A (very efficient) to G (less efficient).


In addition, we can create a renovation roadmap based on this, which shows renovation recommendations in a more detailed document.

Energy certificate Facts - Check

We have once again summarized the most important facts at a glance to give you a comprehensive guide to the topic of energy performance certificates! In a world where energy efficiency and sustainability are becoming increasingly important, the energy performance certificate is a crucial tool for property owners, tenants and buyers.

Energy Performance Certificate – Types:
There are two main types: The demand-based energy performance certificate analyzes the structural characteristics of a building, while the consumption-based energy performance certificate looks at the actual energy consumption. Both provide insights into energy efficiency.

Necessity of the certificate:

When selling or renting a property, the presentation of an energy performance certificate is required by law. This certificate informs potential buyers or tenants about the energy performance of the building.

Period of validity:

The validity period of an energy performance certificate is usually 10 years. After this period, an update is required to ensure that the information is up to date.

Content of the certificate:

The energy performance certificate contains detailed information on the building’s energy requirements, primary energy requirements and CO2 emissions. This data enables a precise assessment of energy efficiency.

Obligation to present and renew:

The energy performance certificate must be presented to potential buyers or tenants. If the property is sold or rented again, the certificate must be updated. These obligations are crucial for the legal framework and contribute to transparency on the real estate market.

What is an energy certificate?

An energy performance certificate is an official document that assesses the energy efficiency of a building and provides information about its energy consumption and potential savings. It is divided into two main types: the demand-based and the consumption-based energy certificate.


1. demand-based energy performance certificate:
– Analyzes the structural features of the building, such as insulation and heating system, to calculate the theoretical energy demand. This certificate is particularly suitable for new or renovated buildings.


2. consumption-based energy performance certificate:
– Based on the actual energy consumption of the building. This certificate takes into account the way the building is used and is more suitable for older buildings.


The energy performance certificate contains information on the energy efficiency class, the primary energy requirement, the final energy requirement and practical tips on how to improve energy efficiency. It is required by law in many countries and plays a central role in real estate transactions, as it provides potential buyers or tenants with important information about the expected energy costs.


Conclusion: In summary, the energy performance certificate is a crucial document that assesses the energy efficiency of a building. By distinguishing between demand-based and consumption-based certificates, it provides detailed insights into the construction and usage characteristics of a property. The information on energy consumption, energy efficiency class and possible improvement measures helps property owners, tenants and buyers to make informed decisions. With its legal obligation when selling or renting, the energy performance certificate plays a key role in promoting transparency and sustainability in the real estate market.

Who sets the regulations for the energy certificate?

The regulations for the energy performance certificate vary from country to country and sometimes even within individual regions. In principle, however, the issuing and regulation of energy performance certificates is often a matter for national or regional legislation. In the European Union, for example, there is Directive 2010/31/EU on the energy performance of buildings, which obliges member states to introduce the energy performance certificate and meet certain requirements.


In Germany, for example, the energy performance certificate is regulated by the Energy Saving Ordinance (EnEV). In Austria, the Energy Performance Certificate and Reporting Ordinance (EAVG) is relevant. Each country has its own specific laws and regulations that define the scope, the obligations to present and the period of validity of the energy performance certificate.


It is important to find out about the specific regulations in each region, as they can vary considerably. In many cases, energy consultants or qualified experts in the field are consulted to ensure that the legal requirements are met.



Conclusion: In summary, the energy performance certificate is regulated by national or regional laws and regulations that are intended to promote the energy efficiency of buildings. In the European Union, Directive 2010/31/EU is an example of this. At national level, countries such as Germany (EnEV) or Austria (EAVG) have specific laws that regulate the issuing, obligation to present and validity period of the energy performance certificate. Compliance with these regulations is crucial to ensure transparency in the real estate market and to promote the energy efficiency of buildings. In case of uncertainty, it is advisable to contact experts or energy consultants who are familiar with the local regulations.
