Green Roof Technology

Published on 19 May 2022. Written by Reddy Shekar

Buildings affect the environment adversely in many ways. Buildings produce almost 40% of global carbon emission it leads to global warming problems. Methodologies like green roof technology, green buildings, and net-zero energy buildings are necessary to minimize these problems.

A green roof or living roof is a roof of building that partially or completely cover the area with vegetation and a growing medium, planted over a waterproofing membrane. Sometimes it also includes extra layers such as a root barrier, drainage, and irrigation systems. Container gardens on roofs, where plants maintained in pots, are not generally considered to be true green roofs. Rooftop ponds are another form of green roofs, which used to treat greywater. Green roofs are not entirely new concept. In ancient Mesopotamia, green roofs used on temples.

Now, most of the developing countries in the world adopted the green roof technology to improve the quality of the urban environment. Green roofs can be adapted for many purposes such as absorbing rainwater, providing insulation, helping to lower the urban air temperatures and mitigate the heat island effect. The only disadvantage of this system is the high initial cost. There are two types of green roofs,

1. Intensive roofs: - which are thicker and support the wide range of plants. But these roofs are heavy in weight and requires more maintenance.
2. Extensive roofs: - which are covered in a thinner layer of vegetation and are lighter than intensive roofs.

How to install a green roof?

1. Clean and prepare the roof surface by removing the loose material.
2. Rollout the drainage layer on to the roof surface and make sure that filter fleece is at the top.
3. Apply the roof garden layer. Measure the depth of the garden layer to ensure you have enough depth.
4. After that place the vegetation blankets on the garden layer.
5. Apply the water on the roof this will enable the plants root to grow into the garden layer.
6. Repeat the above step for a few weeks to ensure the growth of plants.

Environmental benefits: -

1. Natural habitat creation
2. Filter the pollutants and carbon dioxide out of the air which helps to decrease the disease rate.
3. Remove the heavy metals and pollutants from rainwater.
4. Increase agricultural space.
5. If green roofs installed properly, they can also contribute energy to LEED points.

Financial benefits: -

1. Increase the roof service life.
2. Reduction in energy usage.
3. Increase the real estate value.

Conclusion: With a wide range of applications, green roofs are becoming more popular to adopt all around the world. Green roofs also suitable for commercial, industrial and public buildings.
