Abstract:

To study the indoor air qualities(IAQ)of large commercial office buildings in Hunan province of China and the corresponding improvement methods, the IAQ of a large commercial office building in Changsha in July, 2008, is investigated.A questionnaire survey and field tests are used to collect data.According to the data of twelve rooms in this building, objective evaluation and the subjective evaluation of the IAQ are obtained.Almost all of the environmental parameters in these rooms basically meet the standards of the objective evaluation.But the average concentration of carbon dioxide in most rooms cannot reach the value of the cleanliness standards, 1 255 mg/m³.The average acceptability of the IAQ in these rooms is 71%, which is lower than the value of the ASHRAE 55—1992 standards, 80%.The proper increase in the wind speed and the indoor fresh air supply can greatly improve the objective evaluation and the subjective evaluation of the IAQ.
