This green roof and farm provide a Swiss military blade of solutions — flood control, solar technology, fresh produce, green room for town dwellers, jobs, learning opportunities, and more — for some of our many pressing metropolitan issues. Landscape designer Kotchakorn Voraakhom informs us how it functions.

Could urban centers really be built to enhance the environment? Bangkok, Thailand, landscape designer Kotchakorn Voraakhom, a TED Fellow, believes therefore. Her imaginative work challenges the prevailing convinced that urbanization has got to have a bad effect on our planet, whether it is in the shape of flooding as a result of paved areas, exorbitant power usage, disrupted biodiversity or the temperature island impact.

Along with her company Landprocess, Voraakhom has created an innovative new green roof on the Rangsit campus of Thammasat University, about 25 miles north of main Bangkok. Bangkok is very at risk of catastrophic flooding — in reality, based on the World Bank, nearly 40 per cent associated with town, that will be constructed on a river delta, may overflow yearly by 2030, and also this situation was significantly exacerbated by paved-over earth and intensifying rainy seasons.

The Rangsit green roof is the follow-up to Voraakhom’s award-winning Chulalongkorn University Centennial Park, an 11-acre green room 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 brand new 236,806-square-foot framework — which started in December 2019 — encompasses a flood-water administration system and also Asia’s largest rooftop farm that is organic. “We’ve combined the principles of contemporary landscape architecture with old-fashioned agricultural knowledge to develop a Swiss military knife of ecological solutions, integrating water management, green energy, green public room, and much more, ” says Voraakhom. “Meanwhile, by 2050, 80 per cent of this world’s population will reside in urban centers, and water would be a commodity that is scarce. We must begin city that is using more proficiently to guarantee a protected and sustainable supply of meals manufacturing. ”

The green roof, containing an H-shaped lush landscape, seems like a futuristic mountain with a stone building nestled snugly beneath it. “The mountain features an intricate pattern of zigzagging terraces of planted beds, leading all of the way right down to the underside, ” claims Voraakhom. “When rainwater strikes the roof, it cascades down the zigzags cut into its slopes while being consumed by the soil into the beds. ” The extra water is channeled into four retention ponds – with an ability as high as 3 million gallons in the bottom associated with mound. “The procedure slows down the movement rate of rainwater runoff by 20 per cent in comparison to a concrete rooftop that is normal. This keeps a large quantity of water out from the sewage systems, avoiding the area from flooding during hefty rains, ” she describes. The design of this building additionally will pay respect to 1 associated with the founders regarding the campus, economist Puey Ungphakorn. “‘Puey’ means ‘mound beneath the tree’ or ‘nourishment’ in Thai, ” she adds.

Motivated by Thailand’s rice-growing tradition, the terraced structures had been constructed utilising the rammed-earth that is ancient as they are Voraakhom’s nod towards the agricultural reputation for this area. “once I had been thinking about any of it task, I attempted to consider back once again to the thing I could keep in mind of the area from youth — and rice terraces arrived in your thoughts, ” she describes. “A century ago, this area had been outside the main section of Bangkok city, filled up with woodlands and swamps. A hundred years ago, King Rama V made a decision to devote this area to growing rice, so Thailand could be a significant rice producer when it comes to globe. The master commissioned canals to regulate water, together with area became referred to as Rangsit areas, famed for the terraced hills of rice. ”

The city’s concrete urban sprawl took over through the twentieth century, culminating in major redevelopment whenever Bangkok hosted the 1998 Asian games, in accordance with Voraakhom. The industries had been dug up to support thousands and thousands of individuals. Afterward, the college relocated a branch of its campus to your web web site, and commerce that is dense commercial development sprang up around it. “Today, the university really wants to demonstrate its commitment to sustainability that is environmental its infrastructure in addition to its curriculum, and I also wished to bring the agricultural landscape and tradition back into Rangsit Field being a supply of food, ” she claims.

Voraakhom’s wish has come real: Rangsit Fields now has a rooftop farm that is 1.73-acre. The dome’s stepped terraces are full of naturally grown crops – including a drought tolerant number of rice, and lots of native veggies and natural herbs, including red and green oak-leaf lettuce, Thai 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, in addition to farm should be able to give you the canteens on campus with 20 a great deal of rice, herbs and veggies a providing approximately 80.000 meals, ” says voraakhom year. “The meals waste is composted to fertilize the farm, and water from the retaining ponds is employed to water flowers, producing a completely localized, circular system. ” Since most of the flowers are grown organically, there’s no pesticide pollution that is synthetic. “The farm additionally produces a habitat for pollinators, restoring biodiversity, and decreases the necessity for food transportation, leading to ecological wellness also healthier living, ” she says.

The farm serves as an outside class room and a way to obtain regional jobs, too. Staff hired by the college tend to the plants, and farmers provide workshops on sustainable farming, nutrition and permaculture included in the university’s sustainability curriculum. “Students and community users are invited to take part in regular seeding, harvesting, and so forth, ” says Voraakhom. “Farming is a crucial element of our country’s heritage. The urban farm is training a brand new generation of natural farmers with real-world abilities. In addition it fosters a feeling of community. ”

Not just does the building provide a spot of green into the populous city, it is fueled by green energy. Incorporated into the roof design, photovoltaic panels set up at the top of the mound yields 500,000 watts of electricity each hour. This can be utilized to power the building, including the water pumps that pull water up from the keeping ponds to irrigate the plants throughout the season that is dry. Thanks to built-in passive cooling, there was less significance of energy-intensive air cooling: The roof works to sweden mail order brides protect the building from temperature. Meanwhile, breezes blowing over the keeping ponds fun the air before it goes into the building. “When the wind blows on the water within the ponds, it makes a microclimate which also cools the environment across the building, helping to reverse the metropolitan temperature area impact, claims Voraakhom.

This task, which cost roughly $31.6 million US to construct, offer a compelling demonstration of what’s possible once we rethink the way we can live and flourish within our cities. Are you able to build weather resilience — as well as food manufacturing and community well-being — into all future towns and towns and cities? Voraakhom thinks that numerous aspects can act as a template for urban planners and architects that are striving to construct sustainable metropolitan areas. “The green roof and metropolitan farm at Thammasat University show how climate resilience-focused development can possibly commence to add more ecological advantages than dilemmas, ” she claims. “And possibly also assist resolve a number of the issues of history. ”
