We make accurate embodied carbon assessments accessible to all building stakeholders

We make accurate carbon assessments universally accessible with our cutting-edge Software-as-a-Service (SaaS) and API solutions. With Preoptima, all the heavy lifting is performed seamlessly by our robust backend algorithms (the "Preoptimiser"), enabling a smooth and user-friendly optioneering experience. No more steep learning curves or tedious data input; you can dive straight into data-driven design choices, optioneer quickly, and pivot efficiently right from the conceptual design stage. This approach democratises carbon reduction, ensuring that large enterprises to SMEs across the value chain can embark on their Net Zero journey efficiently and effectively.

    No more waiting for weeks to get crucial carbon data. Our real-time assessments allow you to understand the WLC impact of your designs as they evolve, offering the agility to make instant, informed decisions.


    Extensive WLC optioneering in minutes

    Explore multiple design iterations within minutes to find the most carbon-efficient option that suits your design specifications. With Preoptima, you don't have to trade time for sustainability; you can have both.


    Generative design of structural systems

    Our platform handles the generative design of structural systems whenever you change a building parameter, ensuring the building is accurately remodelled each time and that material and carbon data is updated. 


    Early-stage material quantities take-off & custom assemblies

    Why compromise when you can have it all? With Preoptima, we generate material quantities right from the conceptual design stage, setting the stage for accurate budgeting and streamlined construction. Plus, our unique feature allows you to create custom wall and roof assemblies, offering unparalleled flexibility and control in achieving your sustainability goals.
