Update:Now in Private Beta

Better material choices for lower-carbon buildings.

Compare materials and evaluate assemblies for better-informed decisionswith source-linked data and transparent calculations behind every material choice.

How it works

One workflow, from material to assembly.

Find relevant materials, compare the evidence, then test each choice in context.

  1. 01Materials Library

    Find relevant materials.

    Search a curated mix of manufacturer products and generic materials.

  2. 02Material Comparison

    Compare the evidence.

    Review carbon, technical properties and source documents side by side.

  3. 03Assembly Builder

    Test the choice in context.

    See how a material change affects the assembly’s carbon and thermal performance.

01Materials Library

Relevant materials, ready to compare.

A growing, curated library of manufacturer products and generic materials for better material decisions.

  • See the EPDs and datasheets behind each material
  • Save useful options to favourites and collections

03Assembly Builder · Interactive Preview

Build, test and compare assemblies before you specify.

Combine real products and generic materials from the Materials Library, then use each assembly's embodied carbon, U-value and recycled-content data to make informed design decisions.

Evidence and Methodology

Evidence should remain part of the decision.

ECI is designed to make the information behind a material or assembly choice easier to inspect, not to replace professional judgement.

  1. 01

    Keep the source in view.

    Material records retain the EPDs and datasheets used to support each comparison.

  2. 02

    Compare declared information.

    Carbon, technical properties and lifecycle scope stay visible so that choices can be read in context.

  3. 03

    Inspect the assembly inputs.

    Assembly feedback shows the material choices and calculation inputs behind supported build-ups.

Product Roadmap

From material choices to project decisions.

The aim is simple: make embodied carbon useful across more of the design process.

  1. 01Available in private beta

    Materials and assemblies

    Find and compare materials, then test each choice in an assembly as the design develops.

  2. 02Coming soon

    Projects and teamwork

    Keep materials, assemblies, targets and decisions together across a project team.

  3. 03Planned integration

    Revit integration

    Bring material and carbon decisions into Revit and closer to everyday design work.

  4. 04Longer-term direction

    Design optimisation

    Explore lower-carbon options against project constraints, without hiding the calculations or trade-offs.
