摘要:Low-Cost Flat Housing is the housing for low income group.. It began with a flat which has two bedrooms in each unit, then it was increased three bedrooms. The three bedrooms flat has to fit the floor area of 650 square feet, in which was later revised to 700 square feet. Small overall floor area which comes with small budget allocated for its construction, could lead to poor indoor environmental quality (IEQ) in low-cost flat, if not properly designed. This paper discusses on the occupants’ satisfaction perception of IEQ of a low cost flat in Kampung Teras Jernang, Selangor. The methodologies used in this study are site observation and questionnaire survey. This study concludes that the IEQ in the selected low-cost flat has acceptably fulfilled the needs and quality required by the occupants. However, there is a factor that the building occupants have expressed poor perception, which is the noise pollution.
