| dc.title | A study of ventilation performance and indoor particle levels in church environment in Hong Kong | en_US |
| dcterms.abstract | Hong Kong is one of the most densely populated cities in the world. Land is scarce in Hong Kong, and must be used wisely. Most of churches are constructed in commercial and residential buildings, where hundreds of worshipers have their activities in limited space. The ventilation performances in the church are affected, because of limitation of design guideline and lack of professional opinions and knowledge in Hong Kong. The aim of this study is to investigate of ventilation performance and indoor air particles in environment of churches in Hong Kong. The study was divided into two sections, which involved measurements on indoor air pollutants concentration and a questionnaire survey. Respirable suspended particulates (RSP) was measured by TSI Dust Trak model 8520 monitors and CO2 concentration was measured by Telaire 7001 during 24 hours on Saturday and Sunday. Particulate matters smaller than 2.5 microns (PM2.5) are able to travel deeply into the respiratory tract, reaching the lungs. The measurement of carbon dioxide in an occupied space is an indication of the adequacy of fresh air ventilation. Therefore, this study considers two indoor parameters: PM2.5 and carbon dioxide. The results show that CO2 concentration and particulate levels of churches located in commercial and residential buildings were in excess of Guidance Notes for the Management of Indoor Air Quality in Offices and Public Places and National Ambient Air Quality Standard. Therefore, ventilation performance and indoor air particles in churches located in commercial and residential buildings were unsatisfactory because of inadequate fresh air. On the contrary, traditional standalone church has good and healthy indoor air quality because CO2 concentration and particulate levels can fulfill the requirement of those guideline and standard. | en_US |
