Summary

Nowadays, the economic crisis has affected the everyday living of a lot of families worldwide deeply. The households which are most affected are the ones with low income and which cannot cope with the everyday requirements. One of them is the indoor environmental conditions which may have a significant impact on thermal comfort and health of the residents. Although it is considered that low comfort may occur only in developing countries’ households, recent statistics show that 1.29 billion people all over the world live in absolute poverty.The aim of the present thesis is to deeply analyze the impact of the economic crisis on the thermal comfort of fourteen Greek households during winter 2014. The survey was conducted in a small Mediterranean town namely Rethymnon, Crete, Greece. Fourteen low to middle income urban households were monitored. The research aimed to investigate the thermal comfort, the energy consumption and the percentage of income spent on heating for each household. Temperature measurements of the households were collected from 18thNovember 2013 till 25thFebruary 2014. At the same time, meteorological data for the specific region was collected and in addition, data for the building, the heating and the occupants were gathered. This work aimed to find out whether the occupants of the monitored households were satisfied with the indoor temperature and what actions they did in order to have thermal comfort. The majority of the fourteen households experienced thermal discomfort and the indoor temperature was much lower than the country’s threshold for winter period. Moreover, comparing to the previous years, the energy consumption was considerably decreased, due to the decreased incomes and increased fuel and electricity bills. Specifically, the majority of the households had much less energy consumption the last year than 3 years ago. The occupants tried to achieve this goal by turning the heat on only if it was really cold.As far as the income that was spent on heating is concerned, the majority of the households spent over 10% on heating, this means that the majority is fuel poor. Moreover, it came out that the fuel poor households consumed much more energy than the ones which were not fuel poor.
