Firestone roofing enables Asia’s largest urban rooftop farm

Climate change and urbanization call for new solutions to maintain and improve the quality of life in our cities

 

Green roofs can play an important role, especially when they can mitigate heat island effects, which occur particularly where landscapes have turned from green to gray, like cities. With Firestone Building Products Holcim can now bring greenery back into cities with a range of insulating, cool and green roofing systems.

One great example is the H-shaped roof of Thammasat University, located 40km from Bangkok, Thailand. As the largest urban rooftop farm in Asia, the 22.000-square meter Thammasat University Green Roof incorporates modern landscape architecture with agricultural ingenuity, inspired by traditional rice terraces of Northern Thailand.

The cascading farm levels allow rainwater to be absorbed and stored to grow crops. The green roof also filters rainwater naturally through several layers of plants and soil before it leaves the site and reaches residential water sources and marine ecosystems.

Kotchakorn Voraakhom, CEO and Founder of Landprocess, the landscape architecture firm behind the Thammasat University Rooftop Farm explains: "Rooftops are usually under-utilized, but they can become green spaces that reduce the urban heat-island effect, the environmental impacts of buildings and land use, and can also feed people."

The roof has become a green public space, urban organic farm and outdoor classroom all in one. It is enabled by Firestone’s UltraPly TPO thermoplastic membrane, which offers excellent weathering performance and ability to withstand extreme temperature conditions to make it a very durable waterproofing solution.

Becoming the global leader in flat roofing systems making buildings more resilient and energy-efficient, Holcim is proud to enable green cities around the world from foundation to rooftop.

With 60% of a building’s energy lost through its roof, these technologies play an instrumental role in enabling cool and green roofs.
