“What are the benefits and drawbacks of displacement ventilation?”

 

Displacement ventilation is a technology with quite a bit of potential behind it. These systems typically provide better indoor air quality through natural ventilation. This also saves large amounts of energy and gives it lower airflow rates for the same or better quality. The lacks of mechanical parts improve acoustics which lowers pressure losses through diffusers. Unfortunately, the novelty of these systems means that they are usually not well known by contractors. Their specialized geometry requires coordination of building features and diffuser locations, require larger quantities of air where cooling loads are needed, and the ceiling based filtering systems also means that higher ceilings will be needed.
