Analysis of the Greek Behavioural Pattern in Residences and its Effect on Thermal Simulation Estimates

Occupants’ interaction with the building envelope systems may provide a comfortable indoor environment and lead to a better energy performance of the building. Through questionnaire survey, this study investigates occupant’s pattern of use of windows, shading and air conditioning in Greek residences (mostly apartments) during summer. Results suggest that Greek occupants significantly interact with the building envelope of their houses in order to adapt to the changing environmental conditions and meet their comfort needs. The behavioural pattern derived from the questionnaire survey is being implemented in the simulation study of a typical Greek apartment to analyse the effect of the occupant behaviour on cooling load and on natural ventilation efficiency.
