Intensive and extensive green roofs offer a range of environmental and economic benefits. Because of these advantages, they are an important part of sustainable architecture. Green roofs can be designed in many ways, from simple sedum planting and lawns to sports areas and idyllic urban roof gardens. Modern systems create a living habitat for vegetation above the roof structure.
Extensive Green Roofs: Bring Nature Into the Urban Landscape
An extensive green roof is attractive and has a positive impact on stormwater runoff and temperature. Planning an extensive green roof requires solid technical knowledge, especially when selecting plants. The vegetation is usually close to natural planting and needs minimal care, often only once in spring and once in autumn. Drought-resistant grasses, ground covers, and herbs are common choices. In this type of roof garden, watering is rarely required once the plants are established.
Extensive Green Roofs as Environmental Protection: Advantages
Green roofs reduce heat during hot weather. In summer, they can retain up to 90% of the precipitation that falls on them and help humidify and cool the air. A large green roof can therefore improve the microclimate and create a more comfortable atmosphere. Dense planting can also help filter dust from the air and improve sound insulation in urban environments. High-quality recycled materials can be used in the roof build-up.
Intensive planting areas or lawns
A green roof creates a new habitat above the building. Intensive green roofs offer many design possibilities, including planting beds, lawns, and even small trees where the structure allows it. During dry periods, especially lawn areas need regular watering. However, roof conditions do not have to be worse for plant growth than ground-level conditions when the system is planned correctly. Beneath a green roof, the waterproofing and insulation are protected from UV radiation, heat, and cold. Intensive and extensive green roofs can also contribute to lower energy consumption.
