Investigation of chemical substances in sick houses, sick schools, and sick buildings.
Formaldehyde and volatile organic compounds contained in adhesives and paints used in construction are considered to be the causative agents of health issues for residents, such as sick house syndrome and chemical sensitivity, which have been increasing in recent years. The Building Standards Act applies regulations related to sick house measures to buildings that commenced construction on or after July 1, 2003. The Nisshin Environmental Research Center, a registered work environment measurement organization with the Tokyo Labor Bureau, has extensive experience in measuring indoor environments for sick house, sick school, and sick building conditions during new construction and renovations, providing highly reliable measurement results to our clients. We cater to a wide range of requests, from individuals concerned about sick house issues to construction contractors who need to report measurement results to the relevant authorities, so please feel free to consult us.
