Inomhus- och arbetsmiljön i grund- och gymnasieskolan : En studie i Malå och Norsjö kommuner / Indoor environment in schools : a study in the municipality of Malå and Norsjö (Sweden)

Ohlsson, Ida January 2014 (has links)
The purpose of this study was to examine the school environment in the municipalities of Malå and Norsjö. The study focused on cleaning, ventilation, classroom noise and illumination which are the most important factors for a good indoor climate and a good working environment in school. The study was performed by inspection of school buildings, questionnaire among school children and measurements of CO2. The result showed that all the visited schools did not meet the Swedish standards for cleaning and ventilation, also sound environment and the illumination had inadequacies in some of the classes. The result also showed that the majority of the pupils were satisfied with the indoor climate and working environment. Of the total percentage of pupils surveyed, 35% of the pupils were unsatisfied with the cleanliness of the toilets and 44% reported that the sound level is perceived as disturbing. The measurements of CO2 showed that all schools had concentrations (ranging from 541-926 ppm) below the Swedish standard (1 000 ppm), nevertheless there was indications that these concentrations may increase during a day. In conclusion this study showed that the indoor environment in the visited schools had inadequacies which may have a negative impact of the pupils. To avoid unhealthy, and from a public health perspective, these inadequacies should be attended.

Indoor air quality and post-disaster public housing: a case study of a Japanese post-disaster public housing on the effect of VOC emissions from building materials

Hirota, Keiko, School of Architecture, UNSW January 2006 (has links)
Since the beginning of the 20th century indoor air has produced distinctive pollution problems. The most critical pollutants in relation to indoor air quality (IAQ) are chemical contaminants which, in the form of volatile organic compounds (VOCs), have been identified as arising mainly from building materials. Conventional solutions such as ventilation systems and bake-out processes have been developed, but the IAQ problem, often reported as sick building syndrome (SBS), still persists. This study set out to establish to what extent VOCs may affect the health of occupants in a particular built environment, and how much architectural design factors, the use of particular building materials, and human activities may contribute to the problem of SBS. A further question was to establish to what extent current attempted solutions to IAQ problems, namely ventilation and bake-out, were in practice effective in a specific built environment. While previous research and attempted solutions have focused on work places as areas of concern for SBS, the problem is especially significant in residential housing and is particularly concentrated in post-disaster public housing (PDPH). For this reason the research was based on the case of a PDPH project in Abuta, Japan. To analyse the separate components of the problem, several distinct studies were undertaken. The level of pollutants in the air was analysed by means of chemical sampling of VOCs in two units of the PDPH, while the a SBS survey and assessment of the residents of the entire project, as well as interviews with the building professionals involved was designed to identify the human causes and effects of the situation. The effectiveness of the attempted solutions to the problem were considered by means of a study of the bake-out procedure, and finally an airflow simulation by computational fluid dynamics (CFD) was conducted to consider the design and ventilation features of the units in relation to IAQ. The study results have indicated that IAQ problems existed after the completion of construction. It was found that certain VOC levels were far above the guidelines, and the health hazard symptoms known for these VOCs matched the SBS symptoms found in participants??? health complaints. Interviews with building professionals involved in the project revealed that the lifestyles of the occupants were not seriously considered in the project design. The results of the airflow simulation also revealed problematic aspects of the planning design, exacerbating rather than limiting the pollution problem as intended. The study concludes with a number of recommendations for taking these inter-related aspects of the problem into consideration in future, so that the health of residents is not adversely affected.
