Abstract

In recent years has been increased interest in thermal comfort and air quality of indoor environments related to mechanical ventilation systems and air conditioning. This is especially crucial in hospitals where contaminated air transmission is considered a major cause of acquiring disease for patients, health care professionals and visitors. Moreover, these institutions having different sectors, each one with a speciality and function, require different conditions of environmental comfort, in terms of hygrothermal, air quality, acoustic and luminous aspects. In order to evaluate the air quality under the parameters of thermal comfort and carbon dioxide concentration in air conditioning hospital environments, it was carried out a field investigation in waiting rooms and operating rooms in six hospitals in São Paulo and metropolitan region. For data collection were used portable monitoring devices, suitable for research. The results from data analysis indicated significant problems related to thermal comfort and indoor air quality. Among these problems, it can be highlighted the lack of the differential pressure control between the operating rooms and corridors; the divergence among the optimal operative temperatures to provide thermal comfort for different groups of people with different clothing and activity level, occupying the same environment, in this case, the operating rooms; the disregard with the air changes required, especially in waiting rooms equipped with the splitsystem; besides the lack of standardization among the technical references criteria often used. Under these aspects, it is necessary to improve the knowledge of the interaction between the occupants and the environment, especially where the environmental control is decisive to promote the health.
