Green roofs: lifesavers against summer heat and heavy rain!
In Cologne, the topic of green roofs is becoming increasingly important. Especially in a big city like this, where many areas are sealed, green roofs are a real elixir of life. This is recognized not only by the people of Cologne themselves, but also by experts from the environmental authorities. Local click reports that green roofs not only help to beautify cityscapes, but also have practical benefits. They help regulate the climate, improve air quality and promote biological diversity.
What can you imagine by that? Green roofs can be constructed in different ways. Extensive greening with mosses, herbs and grasses is possible, as is intensive greening that offers space for useful plants and perennials. These green oases on house roofs not only cool the environment through evaporation, but can also store rainwater and release it into the groundwater in a delayed manner. This relieves the strain on the urban drainage systems and at the same time protects the buildings from damage caused by heavy rain and other weather phenomena.
Promotion and support
To make the greening of roofs and facades even more attractive, many cities offer subsidies - including Cologne. Cities subsidize greening through reduced wastewater fees and often have special climate adaptation programs anchored in their development plans. The Federal Environment Agency emphasizes that the promotion of green roofs is urgently needed, especially in large cities with heavily built-up areas and many sealed areas, in order to respond appropriately to the consequences of climate change.
In an evaluation of 15 large cities with over 500,000 inhabitants, it was found that only around 10% of the roof areas were green. That's around 0.8 m² per inhabitant, while the greening rate varies between 5% and 19% depending on the city. So there is still a lot of potential here! And this not only applies to the roofs, but also the facades. Vertical gardens and other forms of greenery should play a greater role in urban planning.
