Registering and creating your profile is essential to get the best out of the E3P Platform. The Platform is based on the contribution of users, therefore, it relies on the community to provide information. In order to gather reliable information, the E3P must guarantee the legitimacy of the users uploading information.

To do so, the E3P has a two-step registration system which we will look into further detail here below.

EU Login Authentication

Before registration to the E3P portal can be done, the user must first register to the EU Login (former ECAS, European Commission's Identification System). EU Login authenticates the user before he can proceed to register and create his profile on the portal. When you click on the Login menu tab the first time you access the E3P you will automatically be redirected to EU Login.

E3P Profile and Registration

Once authenticated by EU Login, the user will be redirected to the E3P portal where he will be prompted to create his profile. The user will be asked to:

a. insert his personal details (Tab 1)

b. Fill out the Domain of expertise (Tab 2), including the selection of one of the six main thematic areas, and to provide further information in order to create a profile that correctly reflects the user's background.

Updating your profile

If you would like to update your profile, or whether you haven't finalised the profile when you first accessed the portal you can do so simply by selecting from the top menu the 'My Tools' tab. This menu item provides the preview of you profile and by selecting the edit icon next to your name you will be brought to the profile page where you will be able to make all the necessary changes.

I would like to start contributing to the European Energy Efficiency Platform. How can I register on E3P?

Registering on E3P is very simple: all you need to do is passing your mouse over the "Login" option in the menu (top right) and click on the "Log in using EU Login" button that appears.

EU Login is the formner ECAS (European Commission Authentication Service). An EU Login account allows you to access large number of online web applications and sites. Having an account on EU Login is not reserved only to the European institutions personel, but it is also available to any citizen that makes a request.

  • If you are working or have worked for a European institution or a European project you might already have an EU Login account and you can use it to log on E3P.
  • If you do not have an EU Login account choose the option "Create an account" and follow the EU Login wizzard to complete your subscription. After providing your name and email address, and accepting the specific EU Login Privacy policy, you will receive a verification email message. Click on the link and validate your email address in EU Login. You will be redirected and logged in the E3P website. At that point, you can surf on E3P.


In order to be able to contribute to the platform, you must create an Expert profile (link).

General (14)

The E3P is continuously evolving.

  • At the moment there is no identical platform.
  • Attention to existing and new initiatives in order to avoid overlapping and useless development
  • The E3P make links and connections with relevant initiatives
  • Interoperability with relevant websites will be addressed in the future

The content of the E3P is validated before being published
Who are the validators ?
Validators are members of the EE experts' community who are registered in the E3P.

They have different options:
First option:

  • start drafting an Article
  • invite other experts to contribute
  • agree on the final text and put the Article in the review process
  • the article is peer-reviewed and published

Second option:

  • write an Article
  • go through the review process
  • publish it
  • open it to comments
  • revise it later (and go once more through the review process)
  • to share your latest findings with the E3P community
  • to seek experts' input to progress in your research work
  • to share EE knowledge that can be useful to others

Any user of the E3P must agree on the E3P Terms of Use
The user agrees that data are shared under the Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0)
This means that the user is free to:

  • Share — copy and redistribute the material in any medium or format

The licensor cannot revoke these freedoms as long as you follow the license terms.
under the following terms:

  • Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made. You may do so in any reasonable manner, but not in any way that suggests the licensor endorses you or your use.
  • ShareAlike — If you remix, transform, or build upon the material, you must distribute your contributions under the same license as the original.

No additional restrictions — You may not apply legal terms or technological measures that legally restrict others from doing anything the license permits.

The E3P is hosted on a server of the Joint Research Centre of the European Commission in Petten (NL).

By using the E3P you agree on the E3P Terms of use, which include, among others, that you agree on data sharing under specific conditions. 

You may consider not sharing data if you do not agree on the E3P Terms of use.

The E3P adopted a very flexible approach: the user defines the structure of the datasets and then uploads them. This approach fits to any kind of datasets.
In fact, datasets should have at least a geographic dimension and a time dimension. That's all.

You are not giving them to JRC, you are sharing them with the E3P community

  • they are made accessible to other experts
  • they can be a dot that will connect with others to build the broader European picture
  • they can help better inform the European EE policy making

The content of the E3P builds upon users' contributions, starting from JRC's knowledge.


It is organised in 6 thematic areas:

  • buildings
  • products
  • cities and urban areas
  • industry
  • transport and mobility
  • energy generation and distribution

and 4 cross-thematic areas:

  • policies and targets
  • technologies and standards
  • economy and finance
  • behaviours and social

The E3P is based on 3 main collaborative tools:

  • Data Hub: share datasets
  • wikEE: collaborate and write wiki articles
  • Community: create working groups

…plus additional tools: publications, news, events, webforms, calls (modelling tools and more to come in the future).

  • any expert can share their data and knowledge
  • they can create working groups and collaborate with experts from inside and outside the European Commission
  • it is run by the Joint Research Centre of the European Commission
  • the content is validated by the Energy Efficiency community

The specific objectives of the E3P are:

  • to share JRC knowledge with the EE community and vice versa
  • to strengthen the European knowledge base on EE through collaboration
  • to make knowledge and data readily accessible to European experts

The E3P is a tool that supports the European Energy Efficiency policy making. 

It is gathering evidence-based knowledge to enhance the SET Plan Energy Efficiency as well as the Energy Union Energy Efficiency pillar.
