On the 5th and 6th of June 2019 representatives of 8 Polish pilot cities took part in the study visit in Hamburg, during which they got familiar with the city’s green roof strategy, observed how it changes the cityscape and visited the most interesting buildings and facilities covered with green roofs and living walls. And their number is increasing from year to year - Hamburg’s objective is to cover with plants up to 100 ha of roof area within the city. New green roofs are constructed both on public utility and private buildings (residential and commercial) and significant part of them will be accessible for people.
The catalogue of presented model projects was very vast and included the ones shortly described below. Many of them have been realised within the strategy and support Hamburg in better management of rainwater and in flood prevention.
