Interview Bouwkwaliteit in de Praktijk

In line with the updated European EN 15804 standard, the number of environment impact categories in the environmental performance calculation expanded from eleven to nineteen on 1 January 2021. Circularity plays a huge role in this. As well as being able to divide the CO2 impact into GWP (Global Warming Potential) fossil and GPW biogenic indicators, recycling and product reuse can also be valued more explicitly against the environmental performance calculation’, stated Jan-Willem Groot, who succeeded Harry Nieman on 1 January 2021 as Director of the National Environmental Database (NMD). NMD facilitates circular construction.
