Welcome to oPEN Lab!

oPEN Lab is an EU-funded project leading the transition to Positive Energy Neighbourhoods (PENs) in Tartu (Estonia), Pamplona (Spain) and Genk (Belgium).

Be part of something BIG - Open Call for Innovators

The oPEN Lab project aims to change the landscape of urban areas in small to medium-sized cities across Europe. oPEN Lab aspires to mobilise innovation and system integration within a combined construction and energy value chain leading existing buildings and neighbourhoods towards a positive energy level. Its participatory approach is rooted in the Open Innovation 2.0 methodology, where industry, government, academia, and participants from the civil society co-create and drive structural changes far beyond the scope of what any organisation could do alone.

oPEN Lab aims to demonstrate multi-building and district-level renovation measures and energy systems, allowing to deliver replicable designs and solutions packages for renovating the existing urban contexts into Positive Energy Neighbourhoods. Three open innovation Living Labs in Genk, Tartu and Pamplona will contribute to making interventions and test combinations of different solutions and study their performance as a unique operating system for accelerating service innovation by adopting cross-sectoral integration.

The oPEN Lab Open Call intends to involve innovators based in Europe that are eager to contribute to the development of Positive Energy Neighbourhoods in one or more of the participating cities.

Applicants can apply alone as a single entity or as a Pilot Group formed of two organisations or more, in which case they will designate a Lead Applicant.

Apply for the Open Call

The Open Call aims at finding innovators who want to test their market-ready products in the three oPEN Living Labs in Genk, Tartu, and Pamplona. This is a chance for innovators to accelerate their route to market entry of their solutions and find a link to potential adopters and clients.

Apply through this form.

Find all information in this application guide.

Who should apply?

oPEN Lab Open Call is aimed at innovators from the whole quadruple helix ecosystem: SMEs, start-ups, large enterprises, research institutes, governments and associations representing citizens. Application from SMEs and start-ups will be highly encouraged and favoured in the evaluation and scoring phase. Applications from individuals will not be accepted. For each application there will always be a Lead Applicant.

Applicants can apply alone as a single entity, or as a Pilot Group formed of two organisations or more.
Individuals cannot apply to the Open Call. In the latter case, the Lead Applicant will coordinate the Pilot Group and is responsible for providing the oPEN Lab project management with reports and feedback for the relevant European Commission auditing. There are no restrictions on the number of organisations that can become part of a Pilot Group. However, applicants need to demonstrate the partners have complementary skills and can deliver the project within the timeline set by the project (see section below).

Applicants need to be based in any of the European Union Member States or countries Associated to Horizon 2020. It is not necessary for the applicant organisations to be located in one of the three oPEN Living Labs (i.e., Tartu, Pamplona, Genk). In fact, oPEN Lab actively encourages demonstrations from organisations coming from different locations with the aim to increase the potential for scalability and replicability of PENs in Europe.

The focus of oPEN Lab is on the enhancement of solutions starting from a Technological Readiness Level (TRL) > 5-6 to achieve an expected pre-commercial readiness by project end with TRL of 7-8. Based on this, the main eligibility criteria for the innovators applying to the oPEN Lab Open Call is to have a solution that has been already demonstrated in a relevant controlled environment (TRL 5 or above).

Why apply?

The oPEN Lab Open Call will enhance the selected innovators capacity by offering them the opportunity to collaborate and engage with end users and other industrial parties in a real-life setting within the three oPEN Living Labs for solutions’ enhancement, tailoring and validation.

Moreover, oPEN Lab will set up an Accelerator Programme to support the innovators in developing a roadmap for commercialisation and market entry of the solutions demonstrated in the oPEN Living Labs, and linking them with future potential clients (e.g., local authorities, project developers but also “integrators”, such as engineering companies, utilities, etc.), as well as with existing business support programmes from EIT KICs and marketplaces (e.g., Smart Cities Marketplace).


Although there is no funding provided for the oPEN Lab Open Call, the innovators will have the opportunity to benefit from the oPEN Lab infrastructure and collaborate with stakeholders from the oPEN Lab quadruple helix network, thereby increasing their promotion, visibility, and access to the market.
