This roof that is green farm provide a Swiss military blade of solutions — flood control, solar power, fresh produce, green area for town dwellers, jobs, learning possibilities, and more — for some of our many pressing metropolitan issues. Landscape architect Kotchakorn Voraakhom informs us how it functions.
Could metropolitan areas really be made to enhance the environment? Bangkok, Thailand, landscape designer Kotchakorn Voraakhom, a TED Fellow, believes so. Her imaginative work challenges the thinking that is prevailing urbanization has got to have a bad effect on the earth, whether it is in the shape of flooding as a result of paved areas, extortionate power usage, disrupted biodiversity or perhaps the temperature area impact.
Along with her company Landprocess, Voraakhom has created a brand new roof that is green the Rangsit campus of Thammasat University, about 25 kilometers north of main Bangkok. Bangkok is very susceptible to catastrophic flooding — in reality, in line with the World Bank, almost 40 % for the town, that is constructed on a river delta, may overflow yearly by 2030, and also this situation happens to be greatly exacerbated by paved-over planet and intensifying rainy seasons.
The Rangsit roof that is green the follow-up to Voraakhom’s award-winning Chulalongkorn University Centennial Park, an 11-acre green area in downtown Bangkok that may capture and hold one million gallons of water with its retention pond and storage tanks and stop it from submerging the town.

Just as if that weren’t impressive enough, Voraakhom’s brand new 236,806-square-foot structure — which started in December 2019 — encompasses a flood-water administration system and also Asia’s largest rooftop organic farm. “We’ve combined the principles of contemporary landscape architecture with conventional knowledge that is agricultural produce a Swiss military blade of environmental solutions, integrating water management, green energy, green public area, and much more, ” says Voraakhom. “Meanwhile, by 2050, 80 % regarding the world’s population will are now living in towns and cities, and water will soon be a commodity that is scarce. We have to start utilizing town areas better to guarantee a safe and sustainable supply of meals production. ”
The green roof, containing an H-shaped lush landscape, appears like a futuristic mountain with a stone building nestled snugly beneath it. “The mountain has pattern that is intricate of terraces of planted beds, leading most of the way down seriously to the underside, ” claims Voraakhom. “When rainwater hits the roof, it cascades down the zigzags cut into its slopes while being absorbed because of the soil within the beds. ” The water that is excess channeled into four retention ponds – with a ability all the way to 3 million gallons at the end associated with the mound. “The process slows along the movement rate of rainwater runoff by 20 per cent in comparison to a concrete rooftop that is normal. This keeps a big quantity of water from the sewage systems, avoiding the area from flooding during heavy rains, ” she describes. The design of this building also will pay respect to a single associated with founders of this campus, economist Puey Ungphakorn. “‘Puey’ means ‘mound underneath the tree’ or ‘nourishment’ in Thai, ” she adds.
Motivated by Thailand’s rice-growing tradition, the terraced structures had been built utilizing the rammed-earth that is ancient and therefore are Voraakhom’s nod towards the agricultural reputation for this region. “once I ended up being thinking about that project, I attempted to believe returning to the things I could keep in mind for this area from youth — and rice terraces arrived in your thoughts, ” she describes. “A century ago, this area had been not in the main section of Bangkok city, filled up with woodlands and swamps. One hundred years back, King Rama V made a decision to devote this area to rice that is growing so Thailand could be a significant rice producer when it comes to globe. The master commissioned canals to manage water, plus the area became referred to as Rangsit areas, famed for the terraced hills of rice. ”
The city’s concrete sprawl that is urban over through the entire 20th century, culminating in major redevelopment whenever Bangkok hosted the 1998 Asian games, based on Voraakhom. The areas had been dug up to support thousands and thousands of individuals. A while later, the university relocated a branch of the campus to your web site, and thick commerce and industrial development sprang up around it. “Today, the college wants to show its dedication to environmental sustainability in its infrastructure along with its curriculum, and I also desired to bring the agricultural landscape and tradition back once again to Rangsit Field being a supply of food, ” she claims.
Voraakhom’s wish has arrived real: Rangsit areas now has a 1.73-acre rooftop farm. The dome’s stepped terraces are filled up with naturally find a bride grown crops – including a drought tolerant number of rice, and several native veggies and natural natural herbs, including red and oak-leaf that is greenThai eggplant, green roselle, Thai red pepper, dill. “We’ve planted almost 50 types of veggies, natural natural herbs and rice. We’ve currently had a round of harvesting, therefore the farm should be able to provide you with the canteens on campus with 20 a lot of rice, natural natural natural herbs and veggies a 12 months, supplying roughly 80.000 meals, ” says voraakhom. “The meals waste is composted to fertilize the farm, and water from the retaining ponds can be used to water flowers, producing a completely localized, circular system. ” Since all of the flowers are grown organically, there’s no artificial pesticide air pollution. “The farm additionally produces a habitat for pollinators, restoring biodiversity, and reduces the necessity for meals transportation, adding to environmental wellness along with healthier living, ” she says.
The farm functions as a outdoor classroom and a supply of neighborhood jobs, too. Staff hired by the university have a tendency to the plants, and farmers provide workshops on sustainable farming, nutrition and permaculture within the university’s sustainability curriculum. “Students and community users are invited to be involved in regular seeding, harvesting, and so forth, ” says Voraakhom. “Farming is a essential element of our country’s heritage. The farm that is urban training a fresh generation of organic farmers with real-world abilities. In addition it fosters a feeling of community. ”
Not merely does the building offer a spot of green within the town, it is fueled by green power. Built-into the roof design, photovoltaic panels set up at the top of the mound creates 500,000 watts of electricity each hour. It is utilized to power the building, like the water pumps that pull water up from the keeping ponds to irrigate the plants through the dry period. Thanks to built-in passive cooling, there was less significance of energy-intensive ac: The roof works to protect the building from temperature. Meanwhile, breezes blowing over the ponds that are retaining the air before it gets in the building. “When the wind blows within the water within the ponds, it generates a microclimate which also cools the atmosphere across the building, assisting to reverse the heat that is urban impact, claims Voraakhom.
This task, which cost roughly $31.6 million US to create, provide a compelling demonstration of what’s possible we can live and thrive in our urban areas as we rethink how. Can you really build weather resilience — and also food production and community well-being — into all future towns and cities? Voraakhom thinks that lots of aspects can act as a template for urban planners and architects that are striving to create sustainable towns and cities. “The green roof and metropolitan farm at Thammasat University show how climate resilience-focused development can maybe start to add more ecological advantages than issues, ” she says. “And possibly even assist resolve a few of the dilemmas of history. ”
