In architecture, theoretical approaches and examples of individual buildings based on these until international regulations and construction standards for sustainable design, we observe a change of scenery, that over time established in the minds of designers as imperative. It is now common knowledge that high consumption of conventional, non- renewable energy, to meet the increasing needs for movement, heating, cooling, lighting, has dramatic environmental impacts caused by the emission of polluting gases, directly affecting the hygiene of the air with which come in contact with the users of the buildings . Wind energy is a force that can and should be harnessed and exploited in order to maximize the contribution of this, to the built environment.
This issue focuses on the techniques of natural ventilation, mainly using the Wind Towers as the main tool for greater utilization of the wind. Through empirical knowledge of the past as a starting point and continuing with new, modern techniques and technology ally, in the understanding of wind power, invented new systems to meet user needs.
Seeking the best comfort conditions in a building during the design, the best solution is often a combination of techniques that encourage natural ventilation and mixed mode, natural and mechanical systems, always for the benefit of the user. Through examples of existing buildings and concepts, including natural ventilated systems using Wind Tower, we discover new ways to improve, as designers, the interior environment of buildings, but also new challenges in the architectural design.
New conditions and data created before our existence. The knowledge and experience exists in natural ventilation and has already launched a route where the building is perceived as a dynamic structure. The transition to the era of "smart" buildings, translates the control of their energy behavior of automatically thinking. However, despite the contribution of the energy design, proper selection and sizing of components of the systems, the user is the one who sets the standards for energy consumption.
