Gaepo Xi Presidence (reconstruction of the former Gaepo Jugong Complex 4, 3,375 households) in Gaepo-dong, Gangnam-gu, Seoul, which had a ‘water crisis’ last June, three months after starting to move into new apartments, and the following month, with water flooding all over the complex, is experiencing ‘noise’ this time . ‘ and ‘vibration’ are noisy.
Some residents of Gaepo Xi recently posted an appeal to all residents, saying that the noise and vibration of the ‘geothermal heating and cooling system’ is making normal life impossible.A geothermal machine room for cooling and heating of community facilities in the complex, such as the ‘Zian Center’, is installed on the first basement floor of eight apartment buildings, and the vibration and noise coming from this is traveling up the walls to the ground floor, causing significant damage.
It is a low-frequency noise accompanied by토토사이트 vibration that has never been experienced before, and one resident was diagnosed with ‘paroxysmal vertigo’ and is receiving psychiatric treatment. Other residents also complained that they were suffering from vomiting and headaches.
One resident who visited the damaged household and heard and felt the noise and vibration said, “It’s a strange noise I’ve never heard before,” and “I don’t think I can live in a house like this.”
Residents say that in addition to the noise caused by the geothermal heating and cooling system, some buildings produce noise and vibration of unknown origin. In fact, when I went to the Gaepozai site on the afternoon of the 12th and the morning of the 13th to inspect it, a ‘loud noise’ was heard in the lobby of some buildings. Regarding this, a GS Construction official said, “This sound is the noise of the air conditioner for ventilation at the community center, and repair work is currently underway.”
Due to these problems, Gaepo Xi stopped operating air conditioners at some community facilities last June, and GS Construction, the contractor of Gaepo Xi, carried out ‘vibration proofing work’ on two occasions. However, some residents say that noise and vibration still persist.
Geothermal heating and cooling systems that utilize the characteristics of the underground to maintain a constant temperature generally produce large noise and vibration. Therefore, it is not applicable to general apartments. Some residents also question why GS Construction introduced this system. Regarding this, a GS Construction official said, “The licensing conditions stipulate that 10% of the energy consumed in the apartment must be used as new and renewable energy, so solar power generation, geothermal heating and cooling, and fuel cells were applied.”However, the nearby Gaepo Xi Brestige (formerly Gaepo Jugong Complex 2) and DH Honor Hills (formerly Gaepo Jugong Complex 3), which use a geothermal cooling system like this complex, have no complaints from residents about noise and vibration.
Some residents are requesting that GS Construction select an external diagnostic company and find a solution based on the diagnostic results. However, GS Engineering & Construction said, “We will wait a little longer to see if additional measures are needed.”
Regarding this issue, the Gaepo Xi Reconstruction Association said, “The legal limit for inter-floor noise is 34 dB, but as a result of measurement through a professional measurement company, it was 30 to 33 dB before the reduction measures, and 19 to 28 dB afterward, which is within the legal standard, so it may be a legal problem.” “There is nothing,” he said.
In the case of DH Xi Gaepo, located near this apartment, a high-speed elevator was installed in a high-rise building, and residents complained of damage due to the ‘roaring noise’ caused by it.
