| Summary: | 碩士 === 國立雲林科技大學 === 營建工程系 === 102 === This research aims to investigate the impact of Thermal Environment, Carbon Dioxide (CO2) and Total Volatile Organic Compounds (TVOC), which can affect the students’ health.The duration of the Indoor Air Quality (IAQ) investigation was from January to March of 2014. The targets for our measurements include seven places and can be devided into three kinds of teaching-related space according to their area sizes and maximal available student numbers at the National Yunlin University of Science and Technology (YunTech). Most of the previous studies in Taiwan focused on the IAQ issue in offices. However, there are few studies on investigating the IAQ issue on campus. Recently, due to the problems of the serious Urban Heat Island (UHI) effect and increased oil depletion, many countries have promoted the issues of energy conservation and carbon reduction. According to the government’s policy, the concepts of green campus have been propagated in most of the schools. Considering that Taiwan is located in a subtropical zone, the maximum daytime temperatures can be higher than 30°C in summer and lower than 20°C in winter. Therefore, through this investigation, we can know the Thermal Environment, the concentrations of Carbon Dioxide (CO2) and Total Volatile Organic Compounds (TVOC) and can examine the benefits obtained from the energy conservation and ventilation in the classrooms during the winters in Taiwan.
According our investigation, all kinds of teaching classrooms generally have insufficient Air Change Rate (ACR). The indoor temperature is higher than the outdoor temperature in the winter. Although the types of air conditioners and devices in the classrooms are different, the concentrations of CO2 are higher than the highest value (1000 ppm) defined by EPA for the requirements of the Indoor Air Quality Management Act. The indoor concentrations of carbon dioxide have exceeded a predetermined value in some of the classrooms before the classes even begin. In three of the classrooms, the measured values of CO2 concentration are above 3000 ppm, which is three times higher than the highest EPA permissible value. In this thesis, we will analyze the measured data in the various teaching areas and then make feasible recommendations on the design and planning of new teaching areas and on the currently used classrooms.The study also found that the TVOC are higher than the maximum value (0.56 ppm) specified by EPA in the swimming pool and Service Center for Construction Technology and Materials at YunTech. Under the guidance of carbon reduction and energy conservation, we hope to build a campus that can preserve a healthy environment for the students in the classrooms.
