Rooftop gardens help reducing the carbon footprint of the building by its soil and vegetation cover, which conserves the building's energy. A rooftop garden has thermal insulating properties that help it cocoon a building from the weather. In a hot climate, that translates to using less air conditioning. Gardens also provide a habitat for wildlife in the city, and their foliage removes harmful toxins and re-oxygenates the air.
A rooftop garden of a building features a sky garden full of greenery and leisure facilities, allowing all occupants to take a break from their hectic work schedules.
