![]() ![]() In this study, we explore dampness and SBS symptoms among the residents of public apartment houses in the city of Asahikawa, Hokkaido prefecture (north island of Japan), to elucidate the effect of dampness on SBS symptoms in relatively old, concrete multi-resident buildings.Īsahikawa is located in Hokkaido, the north island of Japan. Therefore, a study of dampness in Japanese public apartment houses in relation to SBS would be helpful. As the majority of Japanese public apartment houses are old and constructed of concrete, it follows that there will be more dampness, which may result in adverse effects on the residents’ health. In a study of Finnish schools, any damage from moisture to wooden school buildings did not affect fungal concentrations, but the effect of moisture damage in concrete schools was clearly demonstrated by higher fungal concentrations compared with the reference schools. Almost all these Japanese public apartments were reinforced concrete or concrete block buildings. ![]() ![]() have reported that older houses are more prone to water-retention problems resulting from a combination of insufficient heating and ventilation, leading to dampness. However, in Japan, there has been no report about the relationship between dampness and SBS symptoms in old multi-residential buildings.Īccording to the Housing and Land Survey of 2003 by the Statistic Bureau of Japanese Ministry of Internal Affairs and Communications ( ), the peak construction period for public dwellings was the 1970s and that for privately owned rental dwellings was the late 1980s. Two scientific reviews have shown that dampness in buildings appears to increase the risk of health effects, such as coughing, wheezing, and asthma. The relationship between dampness and SBS symptoms in relatively old dwellings has been previously reported in Europe. According to previous reports, exposure to chemicals in the indoor air along with the dampness are related to SBS symptoms in people living in Japanese newly built dwellings. Sick building syndrome (SBS), which occurs in newly built dwellings due to exposure to chemicals such as formaldehyde or volatile organic compounds, has been spotlighted in Japan. ![]()
