The Seoul Metropolitan Government is embarking on the creation of green roofs at the DDP (Dongdaemun Design Plaza) on the largest scale to be seen in Korea so far.
Half of the buildings’ roofs will be planted over an area the size of an international football pitch (i.e., 11,250m2).
Perennial sedums and a lawn will be planted, which should have the effect of making the buildings cooler in summer and warmer in winter, leading to a significant improvement in energy efficiency.
The landscaping work will be completed by the end of July this year with the planting of about 800,000 sedums on the roofs of the Convention Hall (6,048㎡) and the Exhibition Hall (3,032㎡). At the recommendation of a number of horticultural experts, five species of sedums have been selected for the location, namely, Sedum takesimense NAKAI, Geumgang sedum kamtachaticum, Sedum reflexum, Sedum rupestre and Sedum oryzifolium.
These species are characterized by their strong resistance to drought due to their thick fleshy water-storing leaves and stems.
The plants on the completed roofs will be arranged according to four natural colors with the Geumgang Sedum serving as a divider between each section, thereby matching the unique characteristics of the building’s exquisite exterior.
The DDP is surrounded by high-rise buildings like the Doosan Tower and Migliore, whose residents will soon have a great view marked by seasonal changes on the DDP’s roof.
As such, these new green spaces will not only improve the insulation effects of the buildings but also offer a great number of people a breadth of fresh air in the heart of the mega city.
Due for completion by July 2013, the DDP will shortly offer the residents of Seoul a rare space where they can enjoy exhibitions, international conferences and fashion shows in addition to the pleasure of taking strolls and attending events in the adjacent Dongdaemun History & Culture Park.
