Stack ventilation is another natural ventilation option. With stack ventilation, people rely on natural pressure differences between air in various locations to force air up ventilation stacks. This technique is often used in factories, where tremendous amounts of heat can be generated by machinery and manufacturing processes, with the warm air being pulled up the stacks along with odors from the factory floor. 
Stack ventilation is usually facilitated with the use of controllable intake vents / louvres which are located low to the ground, generating a steady flow of fresh, cool air.
One of the biggest advantages of natural ventilation is that it does not cost large amounts of money to run. Mechanical ventilation and electronic climate control can be very costly, and may contribute significantly to the overall energy usage and carbon footprint involved with running a building.
Natural Ventilation with controllable weather louvres and (NLC) Roofavent wind terminals can be a sensible way of working with traditional low energy mechanical ventilation systems to ensure the perfect building environment.
The inclusion of a well designed Brise Soleil / Solar Shading system can help reduce solar gains through large glazed areas by up to 80% in the summer months. This will not only reduce cooling loads but reduce the sensation of over heating caused by the sun on the occupants skin.
