Data-driven design in architecture has the potential to drastically enhance the quality of projects. It's not solely focused on enhancing the end result; data-driven design also streamlines the architectural process itself. It goes further than just streamlining tasks; it's about improving the quality of living environments and assuring sustainability. In this session, we'll tell the story of the journey involved in designing a residential building. By combining data from various sources, we looked at the most-optimal options for a case we studied in Warsaw, Poland. Among these sources are passive solar design, green roofs, wind analysis, building materials assessment, energy use efficiency, resource conservation, and waste reduction—reducing carbon footprint. Additionally, we incorporated some urban-scale geographic information system (GIS) data. All of that would not be possible without Autodesk Forma software, which played the critical role. For us, the role of an architect will never be the same after this journey.
