The quality of air in the indoor environment is dependent on the nature and source of indoorpollutants and the performance of the ventilation system. Increased dilution in a tropical contextimplies a high energy penalty. This paper presents a novel method of addressing IAQ and energyissues. An innovative energy efficient method and means of air-conditioning for an independentcontrol of temperature and humidity of two different air streams has been developed. The SingleCoil Twin Fan (SCTF) air handling unit is further developed to incorporate a new method of airdistribution for an independent control of ventilation air quantity at acceptable indoortemperature and humidity conditions. Recent findings from a prototype SCTF air handling unitand SCTF system are encouraging and significant energy savings are possible.
