Step 1 of 6

Pick the tool that matches your project

account_circle

What you do

Choose the standard, certification, or regulation you need to report against, such as EN 15978, Level(s), LEED, BREEAM, or DGNB.

software-icon

What the software does

Sets up the assessment for you, so the scope, life cycle stages, and indicators already match what your chosen standard asks for.

Step 2 of 6

Bring in your data the way that suits you

account_circle

What you do

Connect from your design software with one of 20+ integrations, upload an IFC model, import an Excel file, enter quantities manually, or sketch a concept in Carbon Designer 3D.

software-icon

What the software does

Takes your data in whatever format you have it, extracts the bill of materials, and matches it to the right LCA data. No re-modelling needed.

Step 3 of 6

See where you can cut carbon

account_circle

What you do

Test design and material options early in Carbon Designer 3D, or compare alternatives later using the results and graphs in your assessment.

What the software does

Shows your carbon hotspots and how much each option saves, so you can make better decisions while they are still easy to make.

Step 4 of 6

Get your results in one view

account_circle

What you do

Open your results as soon as your data is in.

software-icon

What the software does

Calculates all required impacts and shows them in clear charts and tables: by life cycle stage, by building element, and by material, with your benchmark or limit value alongside where one applies.

Step 5 of 6

Understand what drives your result

account_circle

What you do

Look at which materials and elements contribute most, and try out alternatives to see how they change the outcome.

software-icon

What the software does

Ranks your biggest contributors, points out where the largest savings sit, and updates your results instantly when you swap a product or adjust a quantity.

Step 6 of 6

Download a ready-to-share report

account_circle

What you do

Choose the report you need and download it.

Frequently asked questions

Frequently asked questions about construction LCA

Can an LCA be done without material quantities?

Yes. One Click LCA's 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. One Click LCA makes LCAs accessible for all skill levels. Training and customer support ease onboarding. Integrated workflows lead you step by step, and the support center offers guides, videos, forums and practical resources.

Can I optimize cost and carbon in my projects with One Click LCA?

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

How does One Click LCA work when the material manufacturer is unknown?

One Click LCA 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.

Does One Click LCA integrate with BIM and design software?

Yes. One Click LCA integrates with existing databases and design tools. Plugins and imports for 20+ platforms enable smooth data flow with minimal rework, including Revit, Archicad, Tekla, Bentley, Rhino/Grasshopper, IFC, gbXML, Excel BOMs, and APIs.
