MaterialScore
MaterialScore evaluates building products across four dimensions: environmental impact, health, transparency, and practicality. Simply enter the name of a product or brand — the tool researches publicly available information and returns a structured score with explanations.
Scores draw on publicly available data. Any gaps are filled with transparent estimates, clearly labeled. Manufacturers can improve their score by publishing product data, certifications, and safety data sheets.
How It WorksThree steps to a score.
-
Type the name of any building material or brand — for example "Kalkfarbe Kreidezeit" or "Osmo Hartwachs-Öl". MaterialScore searches for it automatically.
-
MaterialScore searches publicly available sources: product pages, safety data sheets, certifications, and environmental declarations. No assumptions are made — only verified public data counts.
-
You receive a breakdown across four categories with individual sub-scores and source notes — so you understand exactly what went into the rating and where data was missing.
