In order to comprehensively evaluate impacts extent and relative importance of chemical reaction and ventilation on pollution exposur...
Article
Indoor chemical reaction occurring between ozone (O3) and occupant surfaces (skin, hair, and clothing) is an important source of volatile organic compounds (VOCs) in the indoor air. This kind of chemical reaction can bring obvious impact on indoor air quality (IAQ) and building occupant health. Theoretical model describing indoor occupant surface c...
Article
Protection of indoor air quality and human health can be achieved via ventilation, which has becomes one of the most important tasks for sustainable buildings. This approach also requires highly efficient and energy saving methods for modern building ventilations consisting of a set of parameters of the complex indoor system. Therefore, the advance...

Ozone reactions with human surfaces (skin, hair, and clothing) are an important source of volatile organic compounds in the indoor air, which play an important role in indoor air quality and building occupant health. It's the purpose of this study to obtain the characteristics of air change rate (ACH) and reactants concentration impacting human sur...
Article
To investigate the temporal and spatial behavior of particulate matter (PM10 and PM2.5), daily data of PM10 and PM2.5 mass concentrations were collected from five air–quality monitoring stations in Chengdu from March 2013 to February 2014. In this period, the daily average concentrations of PM10 and PM2.5 were 156.6 and 99.5 μg/m³, respectively, wh...
Article
This paper introduces a new-type of antigravity mixing method, which was applied in the biogas production process, using organic wastewater fermentation. It was found that the digesters with two designs, a high-position, centralized pressure outlet and a high-position, dispersed pressure outlets, both lead to an increase in biogas production rates...
Article
Owing to effect of air permeability, thermal radiation adsorption and thin thickness, low thermal inertia and resistance of tent envelope become one fundamental reason causing poor indoor thermal environment of tent. For the sake of improving thermal performance of tent envelope, composite structure was proposed and applied in tent, including outer...
Article
For natural ventilation, setting upper vents of urban highway tunnel is one possible method for improving the environment and the outlet of the tunnel. In this present paper, one 1,000 m tunnel is chosen as the analysis object, according to the universal size of road tunnel. The relationship between the number of upper vents groups and pollutant di...
Article
As chemical reaction can significantly alter concentrations of indoor pollutants and reaction products often are more irritating than their precursors, indoor gas chemical reaction is one significant factor affecting air quality and occupants' health and comfort. Meanwhile, reaction level and product quantity depend on reactants concentration and r...
Article
In addition to carbon dioxide, human bioeffluents are emitted during the occupant metabolism process. Human bioeffluents should be chosen to provide the comprehensive indication of indoor air pollution caused by occupant metabolism. The relationship between the “common core” quantity of human bioeffluents in the respiratory region and indoor occupa...

Advantage of phase change material provides one possible way to improve thermal performance of lightweight envelope. This study analyzed the thermal performance of lightweight envelope with and without PCM and presented their diffe...
Conference Paper
In this present study, the indoor thermal environment of current rural house located in the southwest region of Shandong Province was tested and analyzed; the measured parameters include air temperature and relative humidity. The results show that the indoor air environment temperatures of all rural houses are below 2.6 degrees C, which are far awa...
Article
Phenomenon that people's adaptation to indoor air pollution is very complicated and impacted by multiple environmental parameters and diverse personal factors. At present, there isn't available data for quantifying the adaptation phenomena of Chinese subjects. Meanwhile, it is necessary to determine that how people response to indoor air combined p...
