GBE’s Carbon-and-Thermal Wall Calculator
A French-language calculator for configuring a GBE double wall and estimating its thermal properties and carbon impact.
- For
- French building engineers and façade designers
- Worth noticing
- It separates static and dynamic RE2020 carbon views and warns that reinforcement quantities are assumptions, not FDES data.
Field notes
The workflow separates the wall into exterior concrete, insulation, and structural concrete, with editable thicknesses and concrete conductivity assumptions. Its thermal calculation explicitly excludes thermal bridges, while the carbon method distinguishes direct use of an applicable insulation FDES from a projection when no integrated declaration covers the entered thickness. Reinforcement ratios are described as estimates rather than declaration data; the page directs users to substitute project-specific reinforcement and have results checked by a BET.
