wienerberger, one of the leading providers of solutions for the entire building envelope.
Objective
wienerberger wanted a digital tool to showcase and compare the CO₂ footprint of different wall setups, based on a study conducted with EPEA. The goal was an engaging, interactive experience that communicates their sustainability work and helps users make informed decisions.
Solution
twigbit partnered with wienerberger to develop CO₂mpare, an interactive online tool that visualises and compares the environmental impact of different wall systems.

The project followed a structured approach:
- Specification workshop — Understood the study's data and aligned on goals, technical requirements and user experience
- Design iterations — Refined the interface across two focused cycles for clarity, usability and brand alignment
- Implementation — Built the tool on robust web technologies for strong performance and an engaging experience
Results
- A user-friendly interface that communicates complex sustainability data clearly
- Strengthened wienerberger's position as a sustainability leader in construction
- A scalable, maintainable solution with ongoing support from twigbit
We continue to collaborate with wienerberger, providing updates, performance optimisations and improvements as user and business needs evolve.
