From material research and product comparison to design optimization and early carbon reduction, Kasper brings revalu’s verified product and sustainability data into one conversation—helping AEC teams make better decisions in minutes instead of hours.
As environmental requirements evolve across Europe, each project involves more data to verify, more variables to consider, and more decisions to coordinate. Kasper was designed to simplify this process, helping teams move forward with greater confidence and ease.

Material decisions often mean moving between different tools, databases, documents, and spreadsheets.
Kasper brings these workflows together in one place, from setting sustainability targets and researching materials to comparing options, assessing carbon, and supporting project documentation. Simply ask a question, and Kasper connects the relevant data and documentation.
Finding the right material information can mean jumping between product pages, EPDs, and technical documents, then making sure everything actually matches.
Kasper does much of that work for you, bringing verified information into a single conversation so you can spend less time searching and more time finding and evaluating the right options.
Choosing between materials isn’t always about finding the option with the lowest carbon footprint. Technical performance, certifications, availability, and project requirements all come into play.
Kasper compares alternatives side by side, highlights key trade-offs, and helps identify the best fit for your project priorities, making it easier to see where changes can have the greatest impact.
The earlier you start assessing embodied carbon through LCA, the more opportunities you have to reduce it.
Kasper helps match materials with EPD data, identify carbon hotspots, and test lower-impact alternatives, so you can find meaningful carbon savings while there is still time to influence the design.
Less time searching. More time designing. Better material decisions at every stage of a project.
Early testers and users of Kasper include Henning Larsen, Herzog & de Meuron, LINK Arkitektur, Park Associati, Werner Sobek, CREE, and more.
