Alia · AI-assisted LCA

From bill of materials to a working model.

Upload a Bill of Materials, BIM schedule or spec diagram. Alia structures it, matches each component to background data, and scales it to the right quantity. Create a fully transparent LCA model in a fraction of the time.

Confidence (0–100): how well Alia rates the dataset against the BoM line; low scores go to review.

How it works

Three stages. You approve each one.

  1. Components

    Upload a BoM, BIM file or spec diagram as a spreadsheet, PDF or image. Alia extracts the components into a structured table and flags missing names, quantities and units. Fill them in yourself, or assign them to a colleague or supplier.

  2. Background data matching

    Alia matches each component to a dataset from the Library and scores its confidence. Low-confidence matches are flagged for review, and any match can be swapped for a different dataset.

  3. Scaling

    Alia scales each dataset to the component's quantity, converting units, and calculates properties such as area, volume and density from dimensions where it needs them.

Built for review

AI you can check.

Alia never hides a decision. Every match shows its confidence, choose matches to flag for review, and override any AI-made decision with your own pick. Change components and scaling values later, or rerun AI tasks for just the components you choose.

  • Confidence scores for every match
  • Set confidence thresholds for review
  • Bulk review flagged items
  • Only changed rows are processed again

Features

Everything between the spreadsheet and the model.

Any bill of materials in

Excel, Numbers, CSV, PDF or a photo of the list. Alia turns it into a structured table.

Confidence on every match

A confidence score on each match, and a threshold you set for what needs a human look.

Quality flags you configure

Flag unexpected terms, values out of range and components that would be counted twice, then review flags in bulk.

Ask a colleague or supplier

Assign cells with a comment, and Alia emails them a link to a short form. Suppliers don't need an account.

Life cycle phases, then Gesserit

Classify components by life cycle phase or EPD module, then open the finished result as a static, traditional LCA model.

Part data, filled in

Alia calculates properties from dimensions, and for electronics can pull part properties from Nexar, with a link to the source.

Questions

Good to know

Does Alia replace the practitioner?
No. AI is built natively into Alia, and every action it takes is reviewable and editable. Alia replaces rote work, not expertise: practitioners stay in control.
What if my file is incomplete?
That's normal. Alia flags missing names, quantities and units, and you can fill them in yourself or assign them to a colleague or supplier with a comment.
Which databases does Alia match against?
Any database in Circa's Library, including ecoinvent, Carbon Minds, AGRIBALYSE, the US Federal LCA Commons, Building Transparency's EC3 and REEL LCI. Background datasets are selected by applying filters to the Library, and Alia then matches each component to the most appropriate dataset.
What does Alia cost?
Circa's software is free to use, including Alia. Data is licensed using credits, based on the amount of data used. Credits are $0.95 each, with no minimum purchase.
Which products does it work best for?
Currently, Alia offers electronics, and building and construction. To request additional sectors, reach out to the Circa team at contact@circa.ai.
