Get reliable construction LCA
for UK projects

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.

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.

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

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.

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.

One Click LCA helps you meet the requirements of over 140 global and regional green building certifications, standards, methods 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.

Yes — One Click LCA is specifically designed to support BREEAM UK New Construction and Refurbishment schemes. It automates the generation of the required Mat 01 life-cycle assessment report, fully aligned with BRE’s methodology, and includes a dedicated BREEAM module to ensure you follow the correct scenarios and calculation stages.

For Mat 01, you’ll receive a detailed breakdown of the building’s environmental impacts and the carbon savings achieved through design optimisations — exactly what assessors need for credit validation. The tool also supports early-stage analysis to help shape low-carbon design from the outset.

For Mat 02, which rewards the use of verified Environmental Product Declarations (EPDs), One Click LCA offers direct access to thousands of UK-relevant EPDs. It helps you demonstrate compliance with minimal effort, summarising EPD use for credit documentation.

For projects targeting innovation credits, enabling the software’s IMPACT-compliant mode aligns the LCA with BRE’s requirements — unlocking the potential for exemplary performance under BREEAM.

Yes — One Click LCA is fully compliant with the RICS Whole Life Carbon Assessment for the Built Environment, the UK’s primary guidance for embodied and operational carbon reporting in buildings.

The tool automatically structures results by building elements (e.g. substructure, superstructure, envelope) in line with NRM and UNICLASS classifications. It reports carbon emissions across modules A to D, accommodates the 60-year reference period, and includes key emissions types — including sequestered carbon for timber or biogenic materials.

This ensures your outputs are ready for any planning submission or WLC report — including those required under the London Plan by the Greater London Authority. For early-stage assessments, Carbon Designer 3D provides RICS-aligned insights to support low-carbon decision-making from the concept stage onward.

Whether for planning, client briefs, or internal targets, One Click LCA provides clear, trusted WLC outputs — consistently accepted by UK authorities and design teams.

The UK construction sector is preparing for future regulation of embodied carbon — and Part Z is at the forefront of that shift. This proposed amendment to Building Regulations would make whole-life carbon reporting mandatory for all major projects in the UK.

While not yet enforced, local authorities (e.g. London, Manchester) and public sector clients (e.g. NHS, local councils) are already asking for WLC assessments as part of planning or procurement. One Click LCA enables you to deliver these assessments today — using recognised standards like RICS, EN 15978, and BS EN 15804.

The platform is “Part Z ready” — it calculates embodied carbon across all lifecycle stages, applies benchmark comparisons, and adapts to new guidance as it’s published. When regulation does arrive, you’ll already be fluent in the required methods, formats, and outputs.

By adopting One Click LCA now, you future-proof your practice and demonstrate leadership in carbon accountability — long before the rules catch up.
