The German Association of Building Greening “Bundesverband GebäudeGrün e.V. (BuGG)” has published the first BuGG Market Report on Green Building 2020 in English to present the most crucial available figures on roof, façade and interior greening in Germany. It intends to provide politicians, industry, construction participants, media and all other stakeholders with current figures on the building greening market each year. The various data are mostly based on research and surveys by BuGG, without any claim to completeness. The focus of the figures from the building greening market is currently still on green roofs, for which data collection methods are relatively straightforward and data can easily be gathered from members and by city surveys.
Green building is no longer a niche product. The green building market is growing and is reflected in a large number of projects. Furthermore, green roofs and facades play an important role as climate adaptation measures, especially concerning heat stress reduction and flash flood prevention.
