Szukana fraza: [Abstract = "Modern materials and construction solutions draw more and more attention to ecology and building certification. Among the criteria appearing in revitalization, an important element is bringing plants back into heavily urbanized areas.

Nowadays, however, there are a number of green roofs and green wall systems, allowing \"greener\" construction without making significant changes in the urban environment."]
