Abstract: Green Mark certified buildings are proposed to have better IEQ than non Green Mark certified buildings. In this study, the occupants’ IEQ perception and prevalence of Sick Building Syndrome (SBS) in an office in a non Green Mark certified and an office in a Green Mark certified are compared to determine if there is any significant difference. A questionnaire was conducted to solicit subjective responses from the occupants on each of the IEQ parameters (thermal comfort, indoor air quality, indoor lighting, indoor noise level and office ergonomics) and their experience with symptoms associated with SBS. Objective measurements were also collected to aid in the discussion. Results from the analysis suggests that there are significant differences in the occupants’ perception in temperature, acceptability of IAQ, cleanliness of air, freshness of air, odours in the air, overall satisfaction with office ergonomic and monitor/keyboard comfort. However, there are no significant differences in the perception of indoor lighting and noise level by the occupants in the two offices. The mean number of SBS symptoms is similar for both offices. The prevalence of each of the symptoms associated with SBS for both offices is similar, with lethargy or tiredness, dry or irritated throat and dry skin among the top three symptoms in both offices. On the other hand, there is a significant difference in the proportion of occupants who indicated that their symptoms went away between the two offices. Office A has higher proportion of people with SBS symptoms than in Office B. Limitations of this study include limited manpower and resources, difficulty in getting permission from other office tenants and the subjective bias associated with questionnaires.
