One Click LCA
vertical specialistBuilding life-cycle assessment software for embodied carbon, environmental impact, and material scenario analysis.
Material and element quantity mapping that converts model data into stage-based life cycle results within one LCA workflow.
One Click LCA calculates building and infrastructure environmental impacts by turning BIM-derived quantities into life cycle assessment results. The workflow centers on importing model quantity data, mapping it to LCA activity and material datasets, and generating stage-based results for reporting.
It supports project-level configuration so repeating an information delivery approach stays consistent across models. One Click LCA also produces exportable outputs for coordination with downstream sustainability and design review steps.
- +Stage-based results that map directly to BIM-derived quantity inputs
- +Consistent LCA configuration across multiple projects
- +Exportable LCA outputs for coordination with sustainability reporting workflows
- +Clear dataset mapping for materials and building elements
- –Dependence on quantity extraction quality from upstream BIM models
- –Limited evidence of deep 4D sequencing or construction phasing automation
- –Rule-based model checking and issue workflows are not a primary focus
- –Automation and API surface for provisioning or governance are not prominently defined

How to Choose the Right BIM Simulation Software
The options separate most on interoperability depth and how much automation they give us around our BIM simulation model inputs and outputs. Look closely at IFC exchange, BCF issue exchange, and automation and API surface, because those decide whether model reviews and scenario runs stay consistent.
IFC exchange round-trip quality
Why it matters
IFC exchange round-trip quality determines whether geometry, properties, and parameters survive handoff between design tools and simulation workflows. If attributes drift, scenario assumptions silently change.
How to check
Ask for a sample model and run an import-to-export loop, then compare key property sets and classification fields. On the demo, request a test that includes custom parameters, not just default fields.
BCF issue exchange for model feedback
Why it matters
BCF issue exchange matters when we want simulation findings to link back to model authoring work without manual rework. Clear issue threads reduce repeated analysis and re-interpretation.
How to check
On the demo, create an issue tied to a specific element and export it, then re-import it into a separate session to confirm the viewpoint and element references remain valid. Ask how conflicts are handled if the target elements have changed.
Automation and API surface
Why it matters
Automation and API surface decide whether scenario runs can be standardized across projects and teams. We care especially when inputs come from spreadsheets, configuration files, or upstream systems.
How to check
Ask to see a scripted workflow (or integration steps) that runs multiple scenarios with consistent parameter sets. Try a quick request: “Change one parameter across 20 scenarios and produce a repeatable report.” Watch what breaks.
Data model mapping for simulation inputs
Why it matters
Data model mapping affects how reliably the tool turns BIM properties into simulation-ready parameters. Poor mapping forces manual editing and increases the risk of scenario drift.
How to check
Request a demo where we map building elements and properties to simulation inputs, including at least one custom property. Confirm whether mappings can be saved as a configuration and reused on a second model.
Configuration and repeatable runs
Why it matters
Configuration and repeatable runs are what keep results comparable between design iterations. We want to avoid rebuilding assumptions from scratch each time the model changes.
How to check
Ask whether runs can be reproduced from saved settings and inputs, not just re-clicking the UI. On a demo model update, test whether previous configurations auto-apply or require full redefinition.
Red flags
- IFC exchange drops key parameters in a round-trip test.
- BCF issue links lose the targeted elements after a model change.
- Automation and API surface only supports single interactive runs.
Fit by situation
- If we hand off models between teams and tools often, prioritize IFC exchange round-trip quality.
- If simulation findings need traceable feedback back to model authors, prioritize BCF issue exchange for model feedback.
- If we run many what-if scenarios with consistent inputs, prioritize Automation and API surface.
Funding and competing interests
This study was co-funded by several of the vendors assessed in it. No single vendor funded it. Funders could propose the market studied.
They had no role in selecting vendors, setting or weighting criteria, analysing data or drawing conclusions, and they received the same factual-accuracy check as every other vendor assessed.
Market definition, inclusion rules and criteria weights were fixed by an editor before research began and did not change afterwards. Editorial process →
