Of the total green buildings that received certification, public houses account for the largest ratio, and they are followed by business facilities and school buildings in proportion.
The total floor area of green buildings in Seoul increased by 16 times in 10 years, from 147,000 square meters in 2004 to 2.421 million square meters in 2012.
Of the total green buildings, public houses accounted for the largest percentage with 46%, and they are followed by business facilities (23%), school buildings (21%), complex buildings (6%) and sales facilities (2%) in proportion.
By autonomous districts in Seoul, ratio of green buildings in Seongbuk-gu is the highest with 65%, and it is followed by Eunpyeong-gu (58%), Jung-gu (53%) and Jungrang-gu (51%).
In contrast, ratio of green buildings in 11 autonomous districts in Seoul, including Seongdong-gu, is lower than 30%, while that in Yeongdeungpo-gu, Seocho-gu, Dongjak-gu and Dongdaemun-gu is lower than 40%.
During the same period, the number of green buildings increased from 1 to 38.
The number of green building certifications received during the past 3 years since 2010 reached 53 on average, and this means that 3.645 million square meters, which account for 35% of new buildings in total floor space of 10.452 million square meters, received certifications as green buildings.
Under the green building certification system, which was implemented in 2002, buildings are classified into 4 grades, ranging from the best grade (Green 1st grade) to general grade (Green 4th grade), based on comprehensive assessment in 7 aspects, including land utilization, traffic, energy, environmental pollution and indoor environment.
According to the Green Building Construction Support Act, public organizations are required to obtain green building certification when they construct a new building or expand existing buildings in total floor area of over 3,000 square meters.
The Act stipulates public business buildings to obtain grade higher than excellent level (Green 2nd grade).
Meanwhile, the Seoul City government tightened criteria than the Act, regulating public buildings with total floor space of over 3,000 square meters to obtain the best grade (Green 1st grade), and general buildings with total floor area of over 3,000 square meters or with more than 20 households to receive grade higher than excellent level (Green 2nd grade).
New buildings that received green building certifications will receive benefits of exempting acquisition tax and property tax by 5~15% and 3~15%, respectively, while exempting 20~50% of levy for environment improvement, depending on grades.
And buildings that obtained the best grade, excellent grade and good grade will be supported with certification processing costs by 100%, 75% and 50%, respectively.
In addition, new buildings will be benefited with ratio of floor area and landscape space to occupy less than 12%, 8%, 8% and 4% when they obtain 1st grade (best grade), 1st grade (excellent grade), 2nd grade (best grade) and 2nd grade (excellent grade) in energy efficiency grade and green building certification grade, respectively.
Director Gwon Min of Green Energy Division at Seoul City government said, “Since improvement of energy efficiency at buildings is a basic solution rather than short-term energy conservation campaign in dealing with shortage in power supply, construction of energy efficient green buildings is very important. We hope companies will actively obtain green building certification that provides tax benefits and support for certification processing expenses.”
