National Institute of Ecology & Ecorium

Character

In 1989, the government announced the Janghang National Industrial Complex. Eighteen years later, six ministries and Seocheon signed an alternative-development agreement, and the National Institute of Ecology followed. The site’s public identity now comes from ecosystems and climate research rather than the industrial estate once planned for the area

The Ecorium makes that reversal physical. Its five major greenhouse environments recreate tropical, desert, Mediterranean, temperate and polar climates inside a 33,090-square-metre complex designed by Samoo Architects & Engineers with Grimshaw

The building does more than shelter plants. Its greenhouse orientation was modeled for each climate zone, airflow simulations informed natural ventilation, and sloped curtain walls collect rainwater for cooling and irrigation. The architects estimated those systems reduced total energy use by about ten percent

The experience

The route changes climate before it changes subject. The tropical hall is the largest and tallest enclosure, rising to 35 metres over more than 3,200 square metres. Official figures list about 700 tropical plant species alongside fish, reptiles and other animals, with humidity held between 60 and 90 percent

The change is measurable before it is interpretive: the tropical hall is held at 60–90 percent humidity, then the route enters a desert climate with far less moisture. Mediterranean, temperate and polar zones continue the sequence, so vegetation, humidity and enclosure change as part of the exhibit itself

That progression works because the greenhouse is only one layer of the institute. Outside, wetlands, Korean forest habitats, ponds, plant gardens and research facilities spread across a much larger campus. The indoor route presents ecosystems as controlled climatic systems; the outdoor zones reconnect the visit to Korean landscapes and seasonal change

The institute is also a working research organization under the Ministry of Environment. Exhibition, ecological research, endangered-species work and environmental education share the same campus, which gives the public areas a different tone from a standalone botanical garden

History

The institution grew out of a regional development conflict. The national government had announced the Janghang industrial-complex plan in 1989, but the project did not proceed in its original form. In June 2007, six ministries and Seocheon County signed a joint agreement for an alternative public-sector development package

Two months later, the National Institute of Ecology site was selected in Maseo-myeon. Its construction master plan followed, and the Ecorium and major outdoor areas were completed in 2012

The institute formally opened in 2013. The law establishing and operating the National Institute of Ecology was enacted that June, the organization was incorporated in October and the opening event followed in December

The architecture preserved the logic of that policy shift. ArchDaily’s project account notes that the site had been allocated for industrial development before the government changed direction, and the Ecorium was conceived as the landmark exhibition building of the new ecological complex

Before you go

The campus is substantially larger than the Ecorium itself. Indoor climate halls and outdoor habitat zones function as separate parts of the visit, so the balance between them changes with weather and season rather than following one fixed museum circuit
