Abstract

The problem of occupant window opening has been increasingly problematic. This is because, in today's world, the role of windows in controlling ventilation is important, particularly when it comes to reducing building energy consumption. Previous research has revealed a general tendency that associated window openings are substantially related to weather conditions, indoor temperature, and various non-environmental factors in different nations, climates, buildings, and room kinds, and in different observation periods. At the study of comfort levels in a place like an office in a building, the majority of researchers agree that these three characteristics are interrelated. Indoor air quality is also a significant influence in determining an individual's level of comfort. The pollutant carbon dioxide (CO2), which is produced by occupants, has a harmful effect on them. This will make an employee unproductive and sick while on the job. As a result, it's crucial to understand how occupants interact with building controls in reaction to variations in both IAQ and temperature. Indoor air quality and thermal comfort are two important aspects of indoor environmental quality that receive considerable attention. Natural daylight that received through window in an office room also give an impact towards occupants. Windows are one of the major means by which building occupants control the indoor environment. If people are uncomfortable, they will take actions including the use of building controls which they think will improve their comfort. Most buildings are not equipped with suitable devices for natural and or mechanical ventilation. In such cases, there is no IAQ control and air changes. The main objectives of this study is to evaluate the indoor thermal comfort conditions of an air-conditioned office through different windows-door opening arrangements. The results gained, when the amount of fresh air supplied by air infiltration is not enough to assure a satisfactory indoor comfort, the occupants cannot achieve their thermal comfort sensation. According to the research, the inability of rooms to open the window in their workplace affects the relative humidity state. It may have an impact on the health of the occupants. The occupant's impression is also influenced by the distance between the office table and the window.
