Sustainable, inclusive, affordable and beautiful solutions for thermal comfort in buildings

The grant opportunity HORIZON-NEB focuses on sustainable and inclusive solutions for thermal comfort in buildings under the New European Bauhaus initiative within Horizon Europe. This initiative aims to develop and demonstrate innovative approaches that prioritize aesthetic appeal, energy efficiency, and environmental sustainability in the built environment. Eligible applicants include a wide variety of organizations such as research institutions, universities, enterprises, non-profits, and public-private partnerships, promoting a transdisciplinary approach. Projects must be consortium-based, requiring collaboration among multiple partners from different Member States or Associated Countries to leverage diverse expertise across architectural design, engineering, and social sciences. The total funding available for this call is €12 million, with approximately €4 million allocated per grant, allowing for an estimated three grants to be awarded. The financial support is provided through a lump sum grant under the HORIZON Innovation Actions mechanism, simplifying budget management and operations for participants. The application process is a single-stage submission, opening on May 5, 2026, and closing on December 1, 2026. Projects should demonstrate at least two thermal comfort solutions across varied climatic zones, including at least one cultural heritage building, evaluate life cycle greenhouse gas emissions and costs, and ensure accessibility for vulnerable groups. Participants are expected to allocate a minimum of 0.8% of the budget for engagement with the New European Bauhaus hub for result dissemination and impact assessment. Success rates for this opportunity are not explicitly stated, but it can be anticipated that competition will be high, with rates typically ranging from 10% to 39% for similar Horizon Europe calls. Co-funding is not explicitly required, allowing projects to potentially cover full costs with the awarded grant. Overall, this grant represents a commitment to advancing sustainable construction practices that integrate cultural heritage and aesthetic beauty, aligning with the EU's environmental goals to become climate-neutral by 2050.

This is a Horizon Europe call focused on "Beautiful, inclusive and sustainable neighbourhoods for communities" (HORIZON-NEB-2026-01). The call aims to develop and demonstrate effective solutions for achieving thermal comfort in buildings while reducing life cycle energy use and GHG emissions. These solutions should be inspired by vernacular principles, nature-based solutions, bioclimatic design, and frugal innovation. The expected outcome is a significantly higher awareness among construction ecosystem actors regarding solutions inspired by vernacular knowledge, nature-based solutions, bioclimatic design, and frugal innovation. The application of developed solutions should help achieve and maintain thermal comfort in buildings, significantly reducing life cycle energy use, GHG emissions, and costs compared to current market solutions. The scope of the call addresses the need to reduce life cycle GHG emissions in buildings to meet the Green Deal’s objectives. It acknowledges that achieving thermal comfort often relies on energy-intensive solutions like air conditioning, which emit GHGs, increase energy costs, and contribute to urban heat island effects. The call seeks to develop and demonstrate beautiful, sustainable, and affordable solutions for thermal comfort inspired by vernacular principles, nature-based solutions, bioclimatic design, and frugal innovation. Proposals are expected to: Develop and demonstrate at least two solutions for achieving thermal comfort in buildings based on vernacular principles, nature-based solutions, bioclimatic design, and/or frugal innovation. Demonstrate the two solutions on new and/or existing buildings, including at least one cultural heritage building, in at least two different climatic zones located in different Member States and/or Associated Countries. Evaluate the reduction in life cycle GHG emissions and life cycle costs, as well as the improvement in affordability, compared to solutions currently on the market. Ensure the accessibility of the solution to groups in a vulnerable situation and the aesthetic appeal of the solutions developed. Identify barriers hindering the implementation, scalability, and replicability of the proposed solutions, including regulatory aspects, and provide recommendations and guidance to overcome them. Proposals should follow a participatory and transdisciplinary approach, integrating different actors and disciplines. Synergies should be explored with other relevant initiatives, such as the EU Mission on Adaptation to Climate Change, particularly the topic HORIZON-MISS-2025-01-CLIMA-04. Proposals are expected to allocate at least 0.8% of their budget for engaging with the Horizon Europe-funded 'New European Bauhaus hub for results and impact' to share their intermediate and final results, findings, and learning, as well as to contribute to impact assessment.

This Horizon Europe call, part of the New European Bauhaus initiative, aims to foster sustainable, inclusive, and aesthetically pleasing solutions for thermal comfort in buildings. The call seeks to reduce the environmental impact of buildings by promoting alternatives to energy-intensive air conditioning, such as nature-based solutions, bioclimatic design, and frugal innovation. Projects should develop and demonstrate at least two solutions in different climatic zones, evaluate their impact on GHG emissions and costs, ensure accessibility for vulnerable groups, and address barriers to implementation. The call encourages a participatory and transdisciplinary approach, requiring applicants to engage with the New European Bauhaus hub and explore synergies with other EU initiatives. Funding is provided as a lump sum grant, and applications are submitted through a single-stage process. The geographic scope includes EU Member States and Associated Countries, with potential eligibility for non-EU countries under specific conditions. This opportunity is geared towards organizations involved in research, innovation, and the construction ecosystem, aiming to create a more sustainable and resilient built environment.
