The innovation of housing has evolved due to several issues such as the affordability and the sustainability of housing. Several housing designs were introduced to meet the affordable housing standard price for the middle-income group, particularly in the urban area. However, it is a challenge for the developers to provide affordable housing within the current market price with the element of sustainability. The developers use the concept of high rise building form and located near the public amenities to accommodate the users’ needs as well as to gain profits. Despite the rising demands, there is a limited study that focuses on the performance of the buildings, specifically on the indoor environmental quality (IEQ) of the affordable housing. This paper aims to assess the affordable housing performance by identifying the residents’ satisfaction level towards IEQ and the importance of the IEQ factors as well as their health condition. A questionnaire survey is one of the methods used in this study. The findings showed that the IEQ of affordable housing in Malaysia has resulted in the decrease of health towards the residents, with some dissatisfaction towards the IEQ. The insight from the residents can be used as an indicator to improve the IEQ as well as the building performance and to create a better affordable housing in Malaysia.
