Beijing’s further promotes green roofs

Beijing city is committed to pursuing the construction of green roofs, that is to say the implementation of rooftop gardens on public buildings lower than twelve floors, China Daily reports. The annual investment would amount to more than 10 million yuan. Although the idea seems like it may benefit many, it has not however been unanimously embraced. Concerned property owners are wary of associated costs and potentially leaky roofs.

After years of trial periods (running since 1984), this greening technique has matured, even though 30% of the 1 million square meters of greened roofs suffer from serious maintenance problems. The green roofs have a positive impact on the temperature of the buildings in summer, and compared to an equal surface area, “land” greening investments would be much more effective.
