Analyzing the Bake-Out Effect in Winter for the Enhancement of Indoor Air Quality at New Apartments in UAE

Indoor air pollution has become a pressing issue in the United Arab Emirates (UAE) due to poor ventilation, inadequate airtightness, and using chemicals building materials. Accordingly, UAE is currently experiencing more cases of sick syndrome (SBS) than any other country. This study aims assess effectiveness bake-out strategy reducing indoor pollutants new apartment UAE. The evaluated reduction toluene (C7H8), ethylbenzene (C8H10), xylene styrene (C8H8), formaldehyde (HCHO) at room temperature relative humidity. airtight unit without winter had higher concentrations hazardous ventilated units, emission dangerous substances increased with temperature. Moreover, harmful were only effectively reduced ventilation times least seven days after heating period. release rate contaminants was lower before. concentration when mechanical combined, resulting 92.8% HCHO. Furthermore, units certain amount maintained low pollutant concentration, regardless whether performed.
