Energy loss may be reduced through the use of warmth exchangers however these have significant purchase, working and upkeep costs. In some structures, increased air flow can actually lead to an increase in indoor air radon levels by inflicting an increase within the underpressure of the indoor air with respect to the subjacent soil gasoline.

When designing buildings for natural ventilation, the design of the roof can play a big role in the air flow strategy. Bernoulli’s precept signifies that as wind speed increases, pressure will lower. Because of this, as wind flows over a constructing, it typically accelerates producing a low stress uplifting force.
