What is bioclimatic architecture , what are their purposes and what is their relation with durable cities ?

it is relates to green architecture, making the most out of the natural ventilation and light source and applying it to the over all concept of the design.

Its that building structure that merges well with the climate or lets say with the climate we should have. Because of the crowded city planning we are living in and the rapid population growth, we are in need of such architecture to balance the need of our human nature where better oxygen is released , self generated power is produced..."elastic" structure that adapts to nature changes...all that might help our mother nature and facilitate our presence in it.

Bioclimatic architecture buildings and spaces based on local climate, meant to running thermal and visual comfort, using solar energy and other environmental sources.

Bioclimatic architecture refers to the design of buildings and spaces (interior – exterior – outdoor) based on local climate, aimed at providing thermal and visual comfort, making use of solar energy and other environmental sources so can resist both the passage of time and stand up to natural disasters.and becme durable.  

Building or houses or spaces designs or strategies that is being based depending on the climate. Self-sufficiency is one of many purposes why bioclimatic architecture strategies are being used.

It's all about sustainable  and Leed,more precise research has to done rather than Aulcomat,Glass,water re-circulation,sewage re-circulation,Led lights,solar adaptation,the idea  of true sustainable is still missing and hope to see true self sustain buildings in near future.

Archi­tec­ture that has a con­nec­tion to Nature. Build­ing designs that take into account   cli­mate and envi­ron­men­tal con­di­tions to help achieve optimal ther­mal com­fort inside. It deals with design and archi­tec­tural ele­ments, avoid­ing com­plete depen­dence on mechan­i­cal sys­tems, which are regarded as sup­port.  A good example of this is using nat­ural ven­ti­la­tion or mixed mode ven­ti­la­tion

The study of the climate applied to architecture, searching with this to improve the conditions of the thermal comfort of the occupants, through the use of appropriate project strategies considering the climatic differences for each place.
