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.

Does One Click LCA integrate with BIM and design software?

Yes — One Click LCA integrates seamlessly with the tools you already use in design and construction workflows. Our software offers direct plugins and import features for over 20 industry-standard platforms, ensuring smooth data transfer and minimal duplication.

For Building Information Modelling (BIM), we offer native plugins for Autodesk Revit and Navisworks, and support for open formats like IFC — making it easy to import data from tools such as ArchiCAD, Tekla, or Bentley OpenBuildings Designer. You can also connect through Rhino/Grasshopper for parametric design workflows, or bring in operational energy data from tools like IES-VE using gbXML.

Quantity surveyors and cost consultants can import Excel-based bills of quantities, while APIs enable integration with custom systems or databases. These connections allow you to automate data capture, eliminate manual entry, and focus on what matters: high-quality life-cycle analysis with reliable, standards-compliant results.

Which certifications, standards, and regulations does One Click LCA support?

One Click LCA helps you meet the requirements of over 80 global and regional green building certifications and carbon regulations. It is fully compatible with:

LEED (including MRc1 LCA credits for LEED v4 and v4.1)
BREEAM (UK, International, and RFO schemes, aligned with Mat 01/02)
DGNB, HQE, Green Star, Level(s), and more

For regulatory compliance, the tool supports EN 15978 (the core building LCA standard), and country-specific frameworks like:

RICS Whole Life Carbon Assessment (UK best practice)
RE2020 (France’s new embodied carbon regulation)
Dutch MPG calculation method
Buy Clean policies in North America (e.g. California and New York)

Whether your goal is a sustainability certification, client brief, planning requirement, or national regulation, One Click LCA provides the tools and outputs to ensure you stay compliant — today and tomorrow.

How accurate and detailed are LCA results made by One Click LCA software?

One Click LCA delivers detailed, scientifically robust life-cycle assessment results that meet the highest standards for credibility and transparency.

The software calculates impacts across all life-cycle stages (A1–A5, B, C, and D) according to EN 15978. Results are broken down by impact category — such as embodied carbon, energy use, water consumption, and waste — with granularity that supports everything from early design comparisons to final audit-ready reporting.

Visual reports, including dynamic graphs and heatmaps, help you identify hotspots — such as which materials or components contribute most to carbon emissions. The level of accuracy depends on your input: specific product and quantity data yield results suitable for certification, while early-stage estimates provide useful design guidance.

Scenario modelling lets you compare design variants side-by-side to make informed, sustainable choices. The methodology is standards-based, fully transparent, and independently verified. You can trace every result to its source, giving you complete confidence in your decisions.
