The results show that for displacement ventilation and wall jet diffusers, with the exhaust opening placed on the wall opposite to the supply opening, arranging chambers in the central area of the office may be better. When the exhaust opening is placed on the same wall...

Results from the study suggested that trained...

...Claire E. Aizlewood; Gary J. Raw; Nigel A. Oseland This paper provides a discussion on the use of the olf and the decipol. The validity of using these units to determine ventilation rates and compare pollution emission rates is discussed, in relation to their derivation and theoretical basis...

...S.C. Sekhar; K.W. Tham; S.E. Lee The problems associated with poor indoor air quality may in most cases be attributed to poorly designed and poorly performing ventilation systems. The problems in a mechanically air-conditioned building are compounded if the building is fairly air tight and depends...

... of energy for heating and/or cooling rises with the effectiveness of ventilation. There is thus a link between the concentration of pollutants overall in the air and the concentration of pollutants in the breathing zone. The consequence of this is that air quality and the efficient use of energy conflict...
