In recent years, volatile organic compounds have caused chemical sensitivity by increasing indoor airpollutant concentrations. In order to solve the problem, Ministry of Health, Labour and Welfare ofJapanese Government established the guideline values for indoor air concentrations for 13 compounds,such as formaldehyde, acetaldehyde, toluene and so on.
Evaluating thermal indoor climate without knowing the conditions is a long and often barrenprocess and documented data is actually not that hard to obtain. A snapshot of the thermalindoor climate in an office building with room for approximately 80 work-places can be takenin only 3 days: 2 days used for measuring and 1 day for reporting. The measuring procedurethat is developed for taking a snapshot is based on ISO 7730.
