Life Cycle Assessment (LCA) is necessary in DGNB to obtain the required credits for a beneficial and lifecycle-oriented planning. You only need to upload the Bill of Materials (BIM, Excel, or gbXML) of your project into the user-friendly cloud service to receive results that comply with DGNB guidelines.

Design greener buildings with automated construction LCA

One Click LCA combines intuitive functionality with the world’s largest LCA construction database, resulting in fast and effective automated life-cycle assessments. 

Integrate with 20+ BIM & other software

Opt for manual entry of building materials and data, or easily import designs from Excel, Autodesk Revit, Rhino, Procore, IFC, IES-VE, energy models (gbXML), among others. Input options also include building areas, energy and water usage, site operations, emissions, and removals for a comprehensive LCA of your building.

Access to over 200,000 data points — including EPDs, generic, and private data

With 200,000+ data points, the One Click LCA database is the largest in the world. It features straightforward navigation, including filters and a search function, for quick access to material EPDs or generic data. The database also enables users to benchmark materials to identify those with the lowest environmental impact.

Streamlines carbon measurement and reduction across all project stages

Use Carbon Designer 3D and BIM integrations for complete project coverage. Understand whole-life carbon impacts and focus on structural and material hotspots.

Frequently asked questions

Learn more about construction LCA with One Click LCA

Can an LCA be done without material quantities?

Yes. The Building LCA tool enables life-cycle assessments at any design stage, even without material quantities. Using the Carbon Designer 3D add-on, you can input building type, gross floor area, and the number of floors to generate initial material estimates.

Is the tool user-friendly for LCA beginners?

Definitely. The tool simplifies life-cycle assessments (LCAs) for users of all skill levels. It includes training and customer support for easy onboarding and assistance. Integrated workflows guide users through each process step, while the customer support center offers valuable guides, videos, and community forums for additional help and user interaction.

Can I optimize cost and carbon in my projects?

Yes, the Building LCA tool enables you to perform both life-cycle assessments and life-cycle costing analysis for the same project simultaneously.

How does the tool work if the material manufacturer is unknown?

No worries, the tool includes a comprehensive dataset on environmental impacts for all construction product types. It incorporates both specific manufacturer EPDs and generic data, ensuring you can find the appropriate match for your project's materials.
