Eco Machine plants remove CO2 and other gases while producing oxygen — indoors and Above Air Flow: Clerestory windows help ventilate the lobby, mechanical room and restrooms. Solar radiation heats the upper air, then natural buoyancy induces stack ventilation, causing the air to push its way out of the open windows and pull in fresh, cooler air from lower windows.
