Finnish SME delivering automated LCA software for construction; specialist in building energy performance, envelope renovation, and digital twins.
One Click LCA is a Finnish construction-tech SME that develops automated Life Cycle Assessment (LCA) software for the building and construction industry, making environmental impact calculation fast, affordable, and accessible at scale. Their core product allows construction professionals — architects, engineers, developers — to calculate the carbon footprint and environmental performance of buildings without specialist LCA expertise. In EU research projects, they contribute this digital tool capability alongside expertise in building energy performance, envelope renovation, and building energy management systems (BEMS). They sit at the intersection of construction software, sustainability measurement, and building digitalization.
Their SME Phase 2 project OneClickLCA (2016–2018, €1.04M as coordinator) was explicitly about transforming the construction industry through automated, affordable, and scalable LCA software.
In ENSNARE (2021–2025), they contribute to a digital framework for building envelope renovation targeting zero energy building standards, covering solar collectors, PV, and BEMS integration.
ENSNARE project keywords include Digital Twin and DST (Decision Support Tool), indicating they are developing or applying digital twin methodology to building renovation workflows.
BEMS appears as an explicit keyword in the ENSNARE project, suggesting involvement in energy monitoring and control system design for renovated buildings.
Their first H2020 engagement (2016–2018) was entirely focused on scaling their own commercial LCA software product — a self-directed SME Phase 2 grant with no listed domain-specific keywords, indicating the work was primarily software commercialization rather than sector research. By 2021–2025, they shifted into a collaborative research role within the ENSNARE consortium, where the keywords pivot sharply toward physical building systems: envelope mesh, solar collectors, PV, BEMS, and digital twins. This suggests a strategic move from pure software vendor toward an integrated digital-physical building renovation player, likely using their LCA tool as a contribution to larger decarbonization-of-buildings research consortia.
They are positioning their LCA and digital tool capabilities as components within broader building renovation and zero-energy-building research programmes — a trajectory that makes them an attractive specialist partner for any Horizon Europe project targeting decarbonization of the built environment.
One Click LCA has both led a project (as SME Phase 2 coordinator) and participated as a consortium member, showing flexibility in role. Their coordinator experience was on a self-focused product development grant, while their participant role in ENSNARE places them inside a larger multi-partner renovation framework — indicating they join consortia as a software/digital tools specialist rather than as a research leader. With 24 unique partners across 12 countries from just two projects, their network density is notable for a small SME, suggesting they attract or seek out diverse European partnerships.
Despite only two H2020 projects, One Click LCA has built connections with 24 unique partners across 12 countries, an unusually broad reach for an SME of this size. No geographic concentration is apparent from available data, suggesting an openness to pan-European consortia rather than a focus on Nordic clusters.
One Click LCA is rare among construction-sector H2020 participants: they bring a commercially deployed, market-tested LCA software product into research consortia rather than developing tools only in research settings. This means any consortium partnering with them gains access to a real product with an existing user base, not just a research prototype. For project coordinators targeting building decarbonization, that combination of software product maturity and EU research credibility is a genuine differentiator.
