Smart farm built on rooftop

A 200-square-meter greenhouse is built on the roof of a high-rise building in the middle of Seoul. This is the nation's first all-in-one rooftop smart farm capable of cultivating vegetables and reducing energy use and carbon emissions. Energy exchange technology was used to control the energy consumption of both the building and the greenhouse.

This technology can cut down on carbon emission by exchanging the carbon dioxide produced within the building with the oxygen generated by the vegetables in the greenhouse. Since the greenhouse is situated on the rooftop where most of the heat is lost, it could serve as insulation in winter and block out the heat in summer.

The research team that developed this technology expects the rooftop greenhouse to save 20% of heating and cooling energy and reduce greenhouse gas emission by 30%. Based on the result of the first city rooftop greenhouse in Korea, the research team plans to continue developing the technology by building a larger rooftop greenhouse on top of a hotel in Seoul next year.
