INDOOR AIR QUALITY CONTROL FOR GREEN HOTELS IN BEIJING

摘要

Indoor air quality (IAQ) issues are very critical for green hotels. Some factors related to IAQ, such as typical indoor contaminants, formaldehyde, NH3, SO2, and NO2, etc, were measured and analyzed in seven representative hotels in Beijing. The results showed that different period of time, different places and even different areas in those hotels exhibited different pollution levels due to differences in sources, location, human activities and ventilation. Based on measurement data and associated with domestic and overseas related standards, a propositional standard of IAQ evaluation for the green hotels with 4 stars or above was proposed.
