What is Bioclimatic Arquitecture?

Bioclimatic Architecture is architecture adapted to environment whose design raises reduce energy dependence by harnessing the energy possibilities offered by the climate of their environment.
A bioclimatic building is the one that adapts to its own environment and takes advantage of it (of solar radiation, air currents, vegetation, etc.), maximizing the design to make your life at home more comfortable, and be able to offer its inhabitants a lower cost when it cool or heat the home life.
Reducing energy consumption in buildings is not only a lower cost to its users, it involves the reduction of pollution associated with their production and reduces dependence on limited fuel.
One of the first factors that will help us reducing energy expenditure is conservation. If we can conserve energy it will reduce the need. There are differents ways to conserve energy in buildings.
• The thermal insulation in enclosures reduced to a quarter of the heat loss through them. Currently there are different specific materials for each situation, logically all used in bio are sustainable, ie that renew themselves. For example, the cork oak, sheep wool, wood fiber, hemp fiber and and in every part of the earth, the closest to the natural resources of the place. Proper insulation will prevent the occurrence of thermal bridges or heat leakages, which are responsible for 20% of the energy lost by the buildings.
• The weakest point thermally in buildings are the glazed openings. Hence, the importance of a correct choice of the frames and the glass. The use of a double glazing or insulating glass significantly reduces energy loss and is an excellent acoustic insulation. Moreover, the tightness of the woodwork will curb losses. For glazed openings with continued exposure to sunlight, you can use low emissivity glass (it means heat less).

The fundamental strategy for housing heat:
Fundamentally these strategies are to harness solar radiation in winter to heat the interior of buildings. The main strategy is a proper orientation of the glazed openings, taking into account the necessary protection to prevent these gains in summer. The optimal orientation is the south, being as more radiation is received. The correct sizing of holes allow the sun to penetrate more in the rooms in winter, as it is lower, while in summer, finding higher, will reduce the angle of incidence and penetration will be less.
It is very important to place materials with great thermal inertia (tabiqueria solid brick, stone walls, brick walls of clay, terracotta flooring, etc.) for heating the house. Not only heat the existing air, but heat up materials so will be the house that keep the temperature much longer.

The fundamental strategy to cool the house:
The main strategy is to prevent and eliminate overheating primarily by ventilation. There are mechanisms to force a natural ventilation, such as solar chimneys. Hot air rises, since it is lighter than cold air. If we place an upper opening (fireplace) in a point inside, preferably in the south facade, which is where most heat is concentrated, and a lower opening such as a window on the north side, a movement of air refresh will occur in dwelling.

Another cooling strategy is the one used in known as andalusian courtyards or in Alhambra, in Granada. These courtyards, pocket cooled air overnight, so that during the day it exchange heat with the rooms surrounding it. Until the air is not heated, does not escape from the courtyards by convection, cooling it again overnight. This system is complemented by placing fountains or water sheeting which evaporate providing freshness to the environment.
