Possible discomfort caused by draft and vertical temperature differences · Possible obstructions to the air flow in the raised floor plenum. 7. CONCLUSION Like many other sustainable features or HVAC technologies, careful planning and holistic design are needed to effectively apply underfloor air conditioning in the building. The benefits of the underfloor approach can be fully recognized when all the influencing factors in the building life cycle are taken into account, including construction costs, life cycle costs, controllability, indoor air quality, and energy performance. A well-designed underfloor air conditioning system can provide improved thermal comfort, ventilation and indoor air quality, and occupant satisfaction and productivity at first costs and energy use similar or lower than conventional ceiling-based systems. The system has the potential to be applied effectively in new and existing buildings. The flexibility and ability to allow inpidual control are the key benefits of the underfloor approach. It is believed that sustainability of buildings can be enhanced by using underfloor air conditioning systems if designers follow sustainable design principles, apply engineering fundamentals in innovative ways, and build confidence based on proven examples. The result will be buildings that are more economical, comfortable, life affirming, and pleasant to be in. REFERENCES Bauman, F. S. and Arens, E. A., 1996.
