$$$$$

Use natural pressure differentials to move air across a floor through a unit or building.

Envelope: air-inlets and operable windows, placed apart from and below air-outlets.
Internally: high louvers or transoms, open door ways.
Building Floor Plate: narrow width of floor plate to increase performance success.

Fresh air is drawn from outside into occupied space and is exhausted with contaminants to the outside at a different location.

Reduced first cost due to smaller mechanical equipment. Lower operational cost due to reduced mechanical ventilation cost.

Access to outside air, improved health, higher performance, less absenteeism, and less operational cost.

Cross ventilation works best when the maximum building depth is 49’ (15m) or less between external facades, and the outside air is at least 3ºf (1.7ºc) cooler than the inside air. Consecutive, uninterrupted air streams are required. Maximize height difference between inlet (low) and outlet (high) for best results.
