The 2022 Green Roof competition in the Czech Republic has a winner
At the end of the conference Green roofs and facades – trends and synergies in Prague, the results of the Green Roof of the Year 2022 competition were announced.
One of the ways to bring nature back to cities and the countryside is the greening of roofs. That is why the Green Roof of the Year competition was created. Its ambition is to introduce the public to the possibility of greening the roofs of buildings and other building structures as part of sustainable construction, environmental protection and the return of green spaces to settlements.
The aim of the competition was not only to draw attention to the possibility of green roofs, but above all to show that in the Czech Republic there are many investors who want to have green roofs on their territory, capable designers who can design them and qualified companies who can build green roofs. The fact that the area of green roofs in the country has more than doubled over the past five years testifies to the dynamics of the development of the field of green roofs. Such results were achieved by the green roofs expert section of the Czech Landscape Gardening Association, which annually determines the total area of green roofs implemented on the territory of the Czech Republic.
The jury of the competition, which visited and evaluated the submitted works, consisted of experts in the field of design and implementation of roof landscaping.
The green roof in the courtyard of Truhlářská Street in Prague became the 2022 winner in a tight race with 7,718 votes.

The Vltava leaves Prague through a narrow rocky canyon. Due to their inaccessibility, islands of natural native fauna and flora survive on the steep slopes…dry-loving, thermophilic communities of rocky outcrops.
