Abstract: Indoor air quality has a vital role in health considerations, it relates to the thermal and human comfort of the indoor occupants, especially patient room in hospital building. In order to gain further more insight into the patient room an air quality monitoring was conducted to identity the comfortable perspective. The monitoring was carried out on three different systems such as naturally ventilated, passive split ventilated and active ventilation in centralised unit in hospital building for two different human load conditions. It's also identical thermal comfort and human comfort on preserved patient occupied room. The use of these findings predicted the relationship between the indoor and outdoor environment about the variable parameters of fresh air supply, temperature flow and human load. The thermal comfort determined through temperature and relative humidity and the improvement of human comfort obtained from the improvement of the reduction of oxides and particulates of measured ventilated patient room. The studied patient room demonstrates that by the air quality monitoring system evaluates various aspects regarding comfortable indoor enhancement, by complying the indoor monitoring factors that successfully ensured the comfort living space. The monitoring results explore how different ventilations could manage comfort indoor, and, therefore, benefit patient and occupant health.

Keywords: indoor air quality; ventilation; human load; fresh air supply; temperature.
