Installing a Green Roof in Luxembourg - Benefits and Design Considerations

Updated: Feb 10, 2023

Green roofs, also known as vegetated roofs, are roofs covered with vegetation and a growing medium. They provide several benefits, such as insulation, stormwater management, and improvement of air quality.

In this blog we want to inform about the benefits of green roofs and basic concepts to consider when designing and installing a green roof.


Benefits

There are many benefits to installing a green roof, including:

1. Environmental benefits: Green roofs can help to reduce air pollution, improve air and water quality, and provide habitats for wildlife. 2. Energy savings: Green roofs can help to reduce heating and cooling costs by providing insulation and moderating the temperature of the building. 3. Increased property value: A green roof can increase the property value of a building by adding aesthetic appeal and improving the overall sustainability of the building. 4. Stormwater management: Green roofs can help to manage stormwater by absorbing and retaining rainwater (up to 80%), reducing the strain on municipal stormwater systems.

6. They produce oxygen, filter polluted air, absorb radiation and thereby improve the overall climate.

7. Longevity: Green roofs can extend the life of a roof by protecting it from the elements and reducing the thermal stress on the roof structure. 8. Noise reduction: Green roofs can reduce noise levels by providing sound insulation. 9. Community benefits: Green roofs can provide green spaces in urban areas, improving the quality of life for residents and helping to create a more livable city. 10. Improved mental and physical health: Studies have shown that exposure to green spaces can improve mental and physical health, reducing stress and improving overall well-being.



Design Considerations

Here are some basic concepts to consider when designing and installing a green roof:

1. Roof Structure: Make sure the roof structure is capable of supporting the weight of the green roof system, including the growing medium, plants, and water. 2. Drainage: Install a proper drainage layer to prevent water from pooling and to ensure proper water management. 3. Growing Medium: Choose an appropriate growing medium that is lightweight, provides adequate drainage, and retains moisture. 4. Plants: Select plants that are suitable for the local climate, able to withstand the harsh roof environment, and have low maintenance requirements. 5. Irrigation: A proper irrigation system is important for watering the plants and maintaining the health of the green roof. 6. Access: Provide access to the roof for maintenance and inspections. 7. Maintenance: Regular maintenance is necessary to keep the green roof healthy and functioning properly.
