摘要

This paper introduces the concept of"building calibration", which characterizes the air contaminants inside indoor spaces. Building users can have a better understanding of contamination status in their surrounding living environment. The calibration process starts with identification of pollutant concentration profile in isolated condition and at different ventilation rates. With known pollutant profiles, the ventilation devices can be optimally operated to meet the prescribed pollutant concentration level. To demonstrate this concept, a comprehensive study in a residential flat in a high rise building in a sub-tropical urban city was carried. The flat is on the 19th floor with wooden furniture and decorative fabrics. The washroom and kitchen are equipped with mechanical exhaust system. Measurement on formaldehyde (HCHO), total volatile organic compounds (TVOC), particulate matter (PM10) and Radon (Rn) was performed at different ventilation rates. The emission factors for various pollutants were obtained. Ventilation rates achieved by different combinations of ventilation devices were verified by tracer gas measurement. In this particular study, increasing ventilation rate reduced the concentration of indoor generated pollutants;however, the particulate matter concentration (indoor-to-outdoor ratio) increased slightly due to the increase in outdoor ingression. The optimal ventilation rate was determined based on the calibration results with consideration of the control on all the pollutants. These results provide a database for ventilation and indoor air quality management. In particular, the formaldehyde and TVOC concentration in the study flat is much higher than the values in indoor air quality standard published by the local government.
