Improving indoor air quality using dynamic insulation and activated carbon in an air permeable ceiling

Research output: Contribution to journalArticle

Abstract

Indoor air pollution has proven negative impacts on the urban population in many developing countries. In Kuala Lumpur, high-rise housing programs are not addressing IAQ and thermal comfort. As household incomes rise, residents are resorting to retro-fitting wall mounted split, air conditioning units; a strategy that is neither cost nor carbon effective. This paper reports on the results of computer modeling in conjunction with scale model trials (1:5) of a ’Dynamic-Hybrid Air Permeable Ceiling’ (DHAPC) designed to filter, cool and dehumidify, the incoming air mass. This filter membrane, when combined with activated charcoal, reduced carbon monoxide, sulphur dioxide, benzene and particulate levels by up to 90%. These techniques now require to be replicated at 1:1 scale, however, the initial data suggests that such an approach, could make a major contribution to improving indoor air quality and thermal comfort with a much reduced carbon penalty.
