Under glossy veneers live substrates, adhesives, fasteners, and backing materials that often account for more emissions than the visible surface. By auditing every layer, designers can specify leaner assemblies that deliver the same acoustics and feel, with smarter detailing and fewer hidden liabilities.
Learn to parse modules A1–A3, A4, and A5, scrutinize the declared unit, check allocation methods, and compare global warming potential across comparable products. Watch for biogenic accounting quirks, electricity grid assumptions, and suspiciously old datasets that distort comparisons in high-stakes selections.
Numbers need narrative: a local limestone with thin bedding, modular cuts, and rail delivery can outperform imported porcelains, while lime plaster may beat gypsum in certain contexts. Evaluate maintenance cycles, replacements, and spares to avoid repeat emissions that quietly erase initial gains.
