BuGG-Market Report on Building Greening 2020
Green Roofs, Green Facades and Interior Greening in Germany
Excerpted translation of the original German version
The German Association of Building Greening „Bundesverband GebäudeGrün e.V. (BuGG)“ has published the first BuGG-Market Report on Building Greening 2020 to present the most crucial available figures on roof, facade 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.
Building greening is no longer a niche product. The building greening 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.
