Modeling and measuring for the Hohenheimer Strasse model project in Stuttgart, Germany

Photocatalysis in concrete terms

→ 1 Calculated relative reduction of the total NO_xconcentration for daytime situations at a wind speed of 0.5 m/s and a UVA radiation intensity of more than 15 W/m² at approx. 1.5 m above ground

Manufacturers of concrete products have been working with photocatalytically active surfaces for a number of years. In collaboration with HeidelbergCement AG, a software tool for quantitative assessment of the effectiveness of such surfaces at a specific location was developed. In a model project conducted by the city of Stuttgart, Germany, the possible effectiveness of photocatalytically active surfaces was simulated on Hohenheimer Strasse in Stuttgart.
