Identifying the relationship between VOCs emission and temperature/humidity changes in new apartments in the hot desert climate

Much previous research in different countries describes a strong dependence on temperature and humidity for indoor air pollutants generated from building materials. Since many types of materials are complexly applied residential buildings UAE constantly using air-conditioning, the result might be characteristics small chamber experiment. This paper aims to investigate relationship between concentration according changes newly built apartments before moving in. As methodology, field measurement was performed 23 housing units five towers Ajman, United Arab Emirates. Before measurement, 7-day bake-out completed, target were measured 30 days The showed that formaldehyde (HCHO) VOCs such as benzene (C 6 H ), toluene 7 8 ethylbenzene 10 xylene styrene ) have consistent within range 15 %–60% relative (RH). It impossible confirm dependency since it each apartment 22°C 33°C. There is limit predicting occurrence only with microclimatic factors there other variables, various materials, management history construction methods. However, proven an emission cut-off point where generation deviates linear RH 40%–50% 25°C. These ranges synchronized daily life ranges.
