“…Chemicals or particles can penetrate indoors through the building envelope, affecting the indoor PM 2.5 levels in real housing units with a controlled indoor-outdoor pressure differences (Choi and Kang, 2017). Therefore, a well-defined performance metrics of air cleaner is need to developed for the indoor air quality management (Hodgson et al, 2007;Yan et al, 2008).…”

Formaldehyde is the most common volatile organic compound (VOC) emitted from household materials and is associated with many health risks, including sick building syndrome. A potted Hedera helix was used as an air purifier to remove the gaseous formaldehyde. Development of a test platform is necessary to evaluate the indoor performance of air cleaning protocols. The box modulation with a novel volatile pollutant-emitting source was applied in an air quality monitoring experiment to mimic a non-ventilated workplace. The environmental conditions and the pollutant concentrations in the air were measured in real time, and the monitoring data was uploaded to cloud storage media by a wireless technique. Compared with natural dissipation, our results demonstrate a 70% decrease in the required time to achieve 1.0 ppm of gaseous formaldehyde using the biological purifier. In addition, the effect of photo-regulation was not significant in the use of potted plants to remove gaseous formaldehyde. Our study provides an accurate and available platform for the public to determine the health risks of VOCs in their buildings.

“…The state space models for indoor environmental contaminants are also proposed for assessing the concentration of indoor particles [11,12] and gaseous pollutants [11,13,14] and their effect on human respiratory tract (HRT) [15]. However, in all of the models, each room is regarded as one zone or multi-zone and the information of indoor flow field is also ignored, hence the temporal and spatial transportation of indoor contaminants cannot be characterized using these models.…”

“…This requires an integrated or coupled model that can simultaneously take into account various factors in the simulation process (Yan et al, 2008). The purpose of this research is to develop a coupled thermal and VOC emission model that can yield the effect of temperature variation on VOC emissions from building materials and to predict the VOC emission rates from building materials and indoor concentrations in residential buildings with radiant floor heating systems.…”

The emission rates of volatile organic compounds (VOC) from building materials and the resulting indoor concentrations are influenced by temperature. Radiant floor heating systems are widely used in most residential buildings in Korea, and VOC emissions from flooring materials increase as the floor temperature rises. In this study, a numerical model is presented to evaluate the VOC emissions from building materials at different temperatures depending on the heating conditions. A coupled model is developed to simulate the temperature variation of building materials and VOC emissions in the floor heated space, which combines the building heat transfer model for materials and indoor air temperature with the mass transfer model for VOC emissions and indoor VOC concentrations. The model was validated by a mock-up test, and it was then used to examine the emission characteristics from flooring materials under different heating conditions. The results show that emissions of VOC from flooring materials tend to increase as the floor temperature rises during the heating condition.
