Indoor air quality assessment within a building of metropolitan areas which is used by vulnerable groups of population
Summary:
In the context of this thesis, experimental results from a typical school building in Athens, equipped partly with a green roof system are investigated. Environmental monitoring took place in six classrooms located both under the concrete and the green roof sectors as well as in the immediate external environment during the warm and cold periods of a school year. Daily measurements of pollutants CO2, TVOC (Total Volatile Organic Compound), PM1, PM2.5, PM10 and airborne fungi were performed in selected classrooms. Moreover, levels of temperature (T), relative humidity (RH) and different ventilation rates were examined, in order to assess the indoor environmental conditions.
The results highlight that during summer, the green roof reduces temperature in a classroom on the top floor, in comparison with the respective classroom under the concrete roof and that relative humidity remained relatively stable for both classrooms. Amid winter, a reverse behavior occurs only for temperature. However, percentages of thermal discomfort remained relatively high for all classrooms during all experimental period. Moreover, air exchange rates (AER) were calculated by using the CO2 as a tracer gas (decay method) within all classrooms. The results demonstrated insufficient ventilation for all experimental sights.
Concentrations of all investigated air pollutants found to be elevated during class hours and significantly affected by activities of pupils and seasonality. However, the different type of roof did not seem to affect significantly the results of indoor air quality regime. Indoor coarse particles (PM10) tend to correlate with specific genera of airborne fungi. In addition, source apportionment of PM10 demonstrated that vechicle exhausts (ambient environment) and resuspension (indoors) found to be the main sources of emission.
This thesis is innovative as it consists the first environmental experiment referring to different types of roof on the same educational building, which is accomplished in Greece.
