The primary driving force of natural ventilation
is the stack effect caused by temperature difference of the shaft compared to the ambient temperature.
As mentioned in the Introduction, the typical estimation of wind driven natural ventilation
flow assumes a simple pressure driven pipe flow and employees the orifice equation, as seen in ASHRAE Handbook Fundamentals (2009), chapter 16.
The result of the intelligent natural ventilation
concepts also impressed the U.
Using natural ventilation
in buildings offers additional benefits besides energy usage reductions.
His topics include physical processes in natural ventilation
, steady and unsteady envelope flow models, contaminant transport and indoor air quality, computational fluid dynamics and its applications, full-scale measurements, and design procedures.
Desco were responsible for the detailed design of the M&E services and the thermal modelling of the internal environment, which helped to minimise the air conditioning requirements by using stack ventilators and cross flow ventilation to maximise natural ventilation

A subset of high-performance buildings, called mixed mode, employs "a combination of natural ventilation
can improve indoor air quality (Finnegan et al.
Plans include a biomass boiler, natural ventilation
, rainwater harvesting and a "green roof".
Light sensors automatically turn off lights in empty rooms and there is a natural ventilation
