A Study on CO2 reduction of the Culture and Performance facility in worship space for Indoor Air Quality improvement

In these modern days, churches are increasing the space for people to rest their minds, and recently, as the top churches are becoming larger in scale, this allows them to accept more members to their church. As the middle and large sized churches of Korea become larger, new problems arise from the increased size of the interior worship space. The problem with air quality in large spaces is that, depending on the building's structure, the interior air flow must be improved to a comfortable level. To address this problem in terms of IAQ development, as size of the worship space increases, so does the CO2 levels, causing the people inside to become tired and fatigued, making it hard to concentrate on their religious thoughts. In this thesis, we installed a Testo 454 to measure CO2 levels and a HOBO (onset) device to measure temperature and humidity levels, and recorded the data over a 2 day period, then analyzed the data in an attempt to find a way to decrease the levels of CO2 in the internal air space of a worship space and determine the optimal IAQ and ACH. The actual data and results given in this thesis are significant to the groundwork for future planning in church architecture, and our purpose is to show the importance of IAQ in church planning, designing, and to the indoor people's safe and comfortable worship space.
