Thermal Comfort and Indoor Air Quality Evaluation of Hospital Patient Ward in Malaysia

摘要

Hospital is one of the most critical buildings in indoor air quality (IAQ) and thermal comfort demand, since the proper indoor environment may effects on health and well-being of both nurse and patient. This study aims to evaluate the indoor air quality and thermal comfort of the patient ward in one of Malaysian hospitals. Indoor air quality and thermal comfort variables measured were temperature, air velocity, relative humidity, CO_2, CO, Total Volitile Organic Components (TVOC), Formaldehyde and Respirable particles compared to global and Malaysian guidelines. Results showed however thermal comfort of the hospital patient ward was in the comfort range, some indoor air pollutant (chemical) such as CO_2 and Formaldehyde exceed the threshold. This finding illustrates the hospital immediate demand of increasing the ventilation rate and fresh air to improve indoor air condition.
