One Click LCA is an online tool for assessing the life-cycle environmental impacts of buildings and construction projects. It supports embodied carbon, whole-life carbon and LCA calculations using data from BOQs, BIM models, material quantities and EPDs.

Digitalization; Circular economy
Objectives
One Click LCA is used to assess and reduce the environmental impacts of buildings across their life cycle. Its main purpose is to calculate embodied carbon, whole-life carbon and other LCA indicators, compare materials and design alternatives, and support better decisions for low-carbon and circular housing. It helps users evaluate end-of-life scenarios such as reuse, recycling, recovery, waste treatment and disposal, making it useful for improving resource efficiency and sustainability in housing projects.
Target audience
Architects, engineers, sustainability consultants, contractors, developers, public authorities, and housing professionals working on LCA, carbon reduction, and circular construction.
Benefits
One Click LCA helps users calculate and understand the environmental impacts of buildings across their life cycle. By using the tool, project teams can identify high-impact materials, compare design alternatives, reduce embodied and whole-life carbon, and support circular economy decisions such as reuse, recycling and end-of-life planning. It also helps improve reporting, support sustainability certifications, and make more informed low-carbon decisions for housing projects.
Data requirements
One Click LCA requires basic project information, such as building type, location and floor area, together with material quantities from a BOQ, BIM model, Excel file or design documents. For end-of-life assessment, users also need assumptions about demolition, reuse, recycling, waste treatment, transport and disposal scenarios.

Other information
One Click LCA is particularly relevant for EXEL4Housing 4.0 because it supports practical carbon assessment, circular economy decisions, EPD use, and end-of-life scenario analysis. It can be used when material quantities, BIM/BOQ data and assumptions for reuse, recycling or disposal are available.
