The present paper correlates aspects of built heritage conservation, occupant's behaviour and thermal comfort. The research focuses on the contemporary architectural intervention of converting original semi-open spaces, that have been acting as such during all periods of the year, into indoor spaces by adding movable glass dividers. A representative building that reflects the typical arrangement of rural vernacular earth architecture in Cyprus is selected for detailed investigation. In situ measurements and simulation tools are used to investigate the adjustment of airflow through the operation of windows when the dividers are open (heating period) and closed (cooling period). Computational Fluid Dynamics are employed in order to illustrate the temperature distribution of various window operation patterns that are evaluated according to the adaptive thermal comfort. The results argue on the climatic adaptability of vernacular buildings and indicate that the examined window control patterns have a more prominent impact during the heating period. Conclusions confirm the cooling potential of night ventilation and highlight the benefit of having energy-aware and engaged occupants. Key directions regarding conservation practices and occupant's behaviour are brought forth, bringing energy efficiency and comfort into the discussion about cultural heritage.
