AIGUASOL CONSULTING SCCL

Their core work

Aiguasol is a Barcelona-based energy engineering consultancy specializing in building energy performance, thermal systems, and smart grid integration. They provide technical expertise in energy simulation, demand response optimization, and building-level energy management — helping projects bridge the gap between energy infrastructure design and real-world building performance. Their work spans from industrial waste heat recovery and heat pump systems to district-level energy storage and renewable energy communities, consistently contributing applied engineering knowledge to large EU demonstration projects.

What they specialise in

How they've shifted over time

In their early H2020 period (2015–2018), Aiguasol focused squarely on thermal engineering and building physics: industrial waste heat recovery, heat pumps, deep renovation, and smart grid control systems. From 2019 onward, their work shifted toward community-scale energy systems, circular economy in housing, and district-level solutions — moving from individual buildings and components to neighbourhoods and energy communities. The most recent projects (AURORAL, LocalRES, ARV) signal a further expansion into digital platforms, rural development, and citizen engagement alongside their technical energy core.

Aiguasol is scaling up from building-level energy engineering to district and community-level integrated solutions, adding circular economy and digital platform capabilities to their thermal expertise.

How they like to work

Aiguasol operates exclusively as a project participant — they have never coordinated an H2020 project, which is typical for a specialist SME that contributes deep technical expertise rather than managing large consortia. With 179 unique partners across 22 countries in 9 projects, they connect widely rather than repeatedly, suggesting they are valued for their specific skills and brought in by different coordinator networks. Their average funding per project (EUR 345K) indicates a mid-sized technical work package role, not a minor subcontractor.

Aiguasol has built a broad European network of 179 unique partners across 22 countries through 9 projects, indicating they are well-connected across different research and industry communities rather than tied to a single cluster. Their Barcelona base and Spanish ecosystem likely give them strong Southern European connections, but their reach is clearly pan-European.

What sets them apart

Aiguasol combines deep thermal engineering expertise (heat pumps, waste heat recovery, energy storage) with practical building simulation and smart grid capabilities — a combination that is uncommon among SMEs of their size. Their trajectory from component-level thermal work to community-scale integrated energy solutions makes them particularly valuable for projects that need someone who understands both the physics of energy systems and how they perform in real buildings and districts. For consortium builders, they offer a rare profile: a hands-on engineering SME that can handle both detailed energy modelling and the integration challenges of multi-technology demonstration projects.

Highlights from their portfolio
