Database system, AFoDAS/AVODAS, on indoor air organic compounds in Japan

Building designers, engineers and occupants often need to estimate the organic compounds' levels in buildings. In order to satisfy the requirement, a web-based database, named AFoDAS/AVODAS database system is developed. The database consists of six databases for managing indoor air organic compounds' levels and building's environmental conditions. The database includes the monitoring results of about 1422 homes. The database allows users to (1) input their monitoring results to the database; (2) browse, search and query the database by a single or combinations of criteria for various query parameters such as building category, ventilation system, environment category, and compound names; and (3) estimate the organic compounds' levels resulting from various buildings and environmental conditions. This paper describes the functionality, database structure and major features of the user interface system of the database.
