This study purposes to investigate the influence of the ceiling height on thermal comfort of the occupants. Creating a comfortable environment is one of the most important parameters to be considered when designing buildings. Human comfort condition usually has investigated by considering climatic conditions and their impact on thermal comfort of people and also changing the variables of thermal comfort equations and calculation of interactive relations. Human comfort is investigated by many researchers from different points of view. In this paper, the effect of changes in floor-to ceiling height on comfort condition in a certain indoor thermal condition is investigated. Also, this study analyses vertical temperature profiles for displacement ventilation depending on a ceiling height of a small office room. This contribution to the discussion on the height of rooms in dwellings in relation to requirements for health and comfort is based on experimental studies and field surveys of householders. It is possible to take advantage of the findings to suggest the optimum height for common urban residential units.
