June 6
World Green Roof Day
World Green Roof Day, established by organizers from the European Federation EFB, falls on June 6 from 2020. The popularity of so-called vegetated roofs is growing year by year, but it is far from just a trendy matter. Green vegetation roofs are functional because they contribute to cooling the house and create a pleasant microclimate, especially in cities, where they replace the missing greenery.
