Ventilative Cooling is an airborne system to utilize air from outside at its actual temperature and humidity. Air transfer may be by natural, mechanical or hybrid means.

Natural ventilative cooling is an aspect of ventilative cooling whose operation is based solely on the effect of wind and the stack effect

Mechanical ventilative cooling is an aspect of ventilative cooling whose operation is based solely on the operation of fans

Hybrid ventilative cooling is an aspect of ventilative cooling whose operation is based on the combination or alternation of natural ventilation and mechanical ventilation
