Summary

Nowadays, the quality of the indoor environment of buildings and indoor air quality are the main issues to be resolved, as they affect the human health to a great extent because of the fact that a person spends most of his day inside buildings.The subject of this thesis is the comparison of indexes of indoor quality with those of the outside environment in order to observe whether the latter can provide reliable results for the quality of the indoor environment of buildings. The study focused on thermal comfort indices and gave useful information for lighting and ventilation of the studied buildings. Has been chosen to examine this issue, as the outdoor environment indexes usually depend on the temperature and air humidity, which are the most important factors affecting the quality of the indoor environment and indoor air. It would also be useful for engineers and researchers to export reliable results without the need for data on all factors, like the indoor indices PMV and PPD, which are mainly used.In order to conduct results the condition of the rooms K1.107, K1.112, K1.101, K2.108 and K2.114 of the buildings K1 and K2 respectively, which belong to the Environmental Engineering School of the Technical University of Crete in Chania, were examined. The indices of the outside environment which were examined are the Humidex Index, the Heat Index and the Discomfort Index and they compared with the results of the PMV and PPD indices, which are considered the most reliable indoor environment indexes, as they used in most of the standards. The data for the calculation of all of the indexes, came from measurements which were made during the summer period of the year 2014. The program which was used to identify the indexes was excel, as there was no need for another more complex program, as shown in the Methodology chapter. The present thesis shows that the index Discomfort Index primarily, but also the index Heat Index can be used to conduct reliable results, while the index Humidex Index is better to avoid.
