Nowadays indoor air quality has increasingly been attracting attention worldwide. In at most dwellings in developing countries, the level of indoor air pollution is very low because there are controls on the design, ventilation and construction of buildings. However, if ventilation of rooms is poor, or household appliances are faulty, pollution can build up to levels which may be detrimental to human health. Sick Building Syndrome is what that comes into concern as this health effect will occur if the occupants are exposed. The purpose of this study was to determine the major sources of indoor air quality either it being influenced by outdoor air and the potential risk of Sick Building Syndrome symptoms to the residential occupancies. Five (5) unit of double storey terrace house randomly selected from different locations in this study. The outdoor and indoor sample were measuring based on indoor gases such as carbon dioxide (CO2), carbon monoxide, total volatile organic compounds(TVOCs) and climates factor such relative humidity, temperature and air velocity to compare the influence factor either from indoor or outdoor. The questionnaire also distributed among respondents. The result indicates from 24 hours measurements for 3 days shows the House 1 (Shah Alam) shows the greatest indoor/outdoor ratio for CO2 and TVOCs. The correlation between indoor parameter such CO2 and air velocity very significant on the day-2, r2=0. 032 And - the correlation between TVOC and CO shows was r2=0. 686 on day-2 measurements. From ANOVA extract, shows symptom were significant between locations such stuffy nose, irritated eyes and a cough. Control measure should take from occupant such increasing the frequent available in ventilation system and use the household product with necessary to reduce the effect to occupant health.
