The green roof’s future vision

Aerial View 21

Sustainability has been an ongoing concern in urban city development and these concerns were perceived as a crucial point for viewing the life cycle of the building.

The design trend of the buildings have changed over time, yet functionality to protect, to give comfort, warmth and coolness has always been the same.

With the increasing demand for eco-friendly designs and technology development, green roofs are going a step further to add new value in the role of buildings in urban planning.

Green roofs are a great solution for the environment. In contrast, urban waterways pollute because falling storm water runs off nonporous sidewalks, roofs, and directly enter the waterways. Green roofs, however,  can absorb up to 90 percent of the average rainfall annually. Much of the water goes back into the natural flow of water circulation.

Although the benefits of green roofs are appreciated and are increasingly well studied, it begs the question as to why contemporary buildings do not practice green roofs till this day.

The Green Roofs effects 

  • Increases green area with vegetation in urban areas
  • Reduces urban heat island effect
  • The plants on green roofs are able to capture airborne pollutants and atmospheric deposition
  • It affects the quality and quantity of atmospheric waters; not only to retain rainwater but also to moderate the temperature of the water and act as natural filters for any of the water that happens to run off
  • The greater insulation offered by green roofs can reduce the amount of energy consumption to moderate the temperature of a building.

The types of Green Roofs

Extensive Green Roofs

The green roof is designed with a natural, soft vegetation that requires minimal maintenance with a standard multi layered design including different functions: a layer that allows the vegetation to grow, to filter, and to drain. However, extensive green roofs need a little more intense maintenance than your conventional ones.

Intensive Green Roofs

The green roof is designed to create the possibility of making a garden on the roof; creating spaces for staying, provided it be given enough water and nutrients.  Intensive green roofs need a much larger maintenance and is more demanding.

Semi Intensive Green Roofs

This is a combination of both extensive and intensive green roofs – adopted to harness both the environmental benefits of green roofs.
