This study introduces room-specific material intensity (RSMI) and proposes a building-level material stock calculation method based on RSMI and floorplans inferred through generative adversarial networks (GANs). Using the RSMI and room-specific areas extracted from the floorplan, the proposed method can calculate material stocks that vary depending on the building design. However, building floorplans on an urban scale are generally restricted. Therefore, the proposed method uses GANs to infer floorplans by analyzing building exterior information, which is obtainable from street view imagery, offering high accessibility and facilitating spatialized analysis.

To test this approach, we apply the framework to Belgium, France, and Germany and find that all three show high effectiveness, albeit Germany ranks highest.

The main reason is SBC's reduced thermal transmittance, which lowers the energy demand for cooling and heating. Using Mexico's climate and typical residential house as a case study, we estimate that SBC buildings can reduce life-cycle greenhouse gas emissions in 29 out of 32 Mexican states over a 50-year lifespan.
