Linz was one of the first cities in the world to introduce a policy making Green Roof construction mandatory.
A rapid industial boom throughout the 1970's took away green space and lead to a significant decrease in air quality. Green roofs were seen as the solution. Green roofs would-
- Essentially 'Reclaim' Green spaces.
- Purify the air
- Provide storm water retention
Initially implemented in 1985 the policy offered rebates up to 30% of the cost of building the Green Roof.
Today Linz has a population of 200,000 people. It is still an important industrial hub for Austria. Most notably for its production of steel.
The emphasis on building or maintaining green spaces has continued. It is extremely evident throughout the industrial area.
Policy at present states that any building with a roof area over 100m2 must have a green roof.
This small supermarket in the residential area of Linz shows further results of the policy. Such a simple way for the city to continue to grow, while maintaining green space.
With strong community support the policy to make Green roof construction mandatory produced the required results. Linz is now clean and green!
Mandatory Green Roof policy has worked in Linz!
