Indoor Environmental Pollution from Ultrafine Particles with Controlled Ventilation in Buildings
Summary:
The present thesis investigates the experimental and theoretical evaluation of
the Indoor Environmental Quality in residential buildings and schools in areas
of Attika with different microclimatic characteristics. Extensive experimental
measurements of air pollutants were carried out while particular emphasis was
given on the recording and analysis of particulate matter (PM) aiming to
determine their generation sources. It was found that PM largely depend on
occupants' activities and on ventilation rates whose levels were extensively
recorded. Furthermore, significant positive correlations were found between PM
and airborne fungi. The perception of the Indoor Environmental Quality and the
assessment of sick building symptoms through a questionnaire survey as well as
the investigation of students' productivity in relation to the levels of air
pollutants were also examined. It was found that temperature was a determinant
for the satisfaction of students with the indoor air quality and the negative
effect of the increased CO2 concentrations to students' productivity was also
established. Finally, PM concentrations were simulated using a mathematical
model and a satisfactory correlation was found between the predicted and
measured PM10 concentrations. The emission rate of PM10 due to the presence of
students was also calculated and a proposal for the optimum management of the
teaching periods was further made.
