Did you know that students in Green Schools have a higher level of academic performance, report lower absenteeism and that there is less faculty turnover too? On top of that, such schools have less operating costs and can spend more on infrastructure development. The reason behind all this is huge savings due to an energy efficient environment and lower utility bills.
All these can be attributed to a key component in HVAC units in green schools – the innovative DV (displacement-ventilation) system. What exactly is it? In simple terms, it is an optimum air distribution approach by which high amounts of low velocity air is pumped out of floor-level diffusers. This displaces and forces out warm air through grills in the ceiling and out into space. The lowering of room temperature results in reduced heat transfer throughout the building, giving a boost to energy efficiency.
Another advantage of the DV system is the improvement in air quality an important factor for children as it pushes up air mixed with pollutants above the breathing level.
