Abstract


Currently, there are about 80% of the time is spent indoors, the air quality is good or bad will directly affect human health. In the past 20 years, long-term living and working in a modern building of more and more people are exhibiting severe pathological reactions, this problem has aroused wide attention from experts and scholars, and soon made sick building (sick building ) and Sick Building Syndrome (SBS) point of view. As people's living standards improve, the air quality of the indoor environment of the increasingly high demand, it is essential to the quality of indoor living environment research. In this paper, the student dormitory in northern China air quality health effects on students were studied, this research work was organized by the Technical University of Denmark international indoor air quality studies as part of the overall plan, mainly for the domestic university student dormitories were large-scale surveys. Components for different students and dormitories Louxing survey questionnaires and field testing using a combination of methods, its main purpose is to analyze to determine our young students to human health and the relationship between indoor air quality. Survey was designed mainly to human health, the environment two kinds of quarters and a subjective evaluation questionnaire member information questionnaire and simultaneous measurement of student hostels temperature, humidity and CO2 concentration and other objective factors, and scientific survey data were collated and analyzed, the various factors affecting the logistic regression analysis. According to the Danish Technical University studies show that the role of CO2 produced by human metabolism as a natural tracer gas to calculate the amount of ventilation is a good method, based on this selection method of the Technical University of Denmark - CO2 method. The findings showed that students dormitory air quality on human health effects attributed to the subjective and objective aspects. Objective aspect of the indoor variety of physical parameters such as temperature, humidity, ventilation rate, building moisture and other objective factors; subjective student's own factors for the interior, mainly in the last 12 months there have diseases, food allergies, outdoor exercise time , sensitive to the outside world and other subjective factors. After scientific analysis of the main conclusions are as follows: 1. Plaster peeling, cracking paint window frames, exterior water damage and other environmental factors on the part of the dormitory symptoms who are risk factors 2. Indoor damp phenomenon, indoor humidity, ventilation rate, etc. factors on the part of the symptoms is a protective factor, temperature and humidity on the part of the symptoms, it is also risk factors 3. past 12 months there have been medical history, to noise, cold, air-sensitive, on the part of the history of food allergy symptoms risk factor is 4 outdoor sports discomfort on the part of the time is a protective factor
