A timed exposure diffusive sampler (TEDS) sensitive enough to measure hourly averages of nitrogen dioxide (NO2) at low parts per billion levels was developed for use in epidemiological studies. TEDS can be used for a variety of atmospheric pollutants. TEDS was tested in the laboratory against known concentrations of NO2 and against well established NO2 measurement systems. It was then tested in the field against the Environmental Protection Agency's reference method for measuring NO2. The TEDS method appears well suited to epidemiological investigations of air quality and extends previous work in this area by offering improved time resolution of changes in pollutant concentration at a cost sufficiently low to permit its use in large scale studies. The TEDS method also shows potential for miniaturization for use in personal sampling.

In February 1994, EPA proposed to "refine" its carbon monoxide (CO) hot spot model, CAL3QHC, to increase its accuracy and reliability. Currently, this proposal includes using hourly meteorological data recorded at airports near the modeling sites instead of the worst case conditions now recommended as a modeling default. The analysis in this study has shown that airport data should be used only on a situational basis as discrepancies exist between airports and local intersections. It is unclear if the added meteorological data will improve CAL3QHC's performance. This study also compares actual CO concentrations and their corresponding meteorology with the worst case modeling defaults. The highest CO levels are occurring at calms (wind speed less than one meter per second) which are not able to be modeled with the current Gaussian dispersion equation in CAL3QHC. Given the findings of this analysis and the lack of other scientific evidence supporting the proposed refinements, recommendations for developing an alternative model improvement plan are outlined. / Graduation date: 1995

Due to the energy crisis in 1970, the energy saving is more important for the human civilization. The energy-saving policy is important for the economic growth and competition of Taiwan. The energy of daily life and business consumes 17% of the total energy, especially the air conditioning of architectures on the peak hours occupying a third in summer. So the building energy-saving policy is the most important in Taiwan. The main of theme building energy saving is not only to save energy but also to consider the comfortable and healthy of the living environment. So that, the optimal design of the building energy saving of commercial buildings in Taiwan has been established in this paper. In this study, theoretical analysis and a full scale experiment has been performed to validate this design. Results showed this design is suitable for the NPTC building in the weather condition of south Taiwan, which also complies with the energy code of Taiwan.
