The Bio-climatic design and the energy saving
A possible definition of “bio-climatic architecture” would be that use of integrated solutions that create conditions of physical comfort inside a building all year round using the minimum amount of non renewable energy. So, taking this as its point of departure, a project needs first to study the volumes and orientation of the building. Compact forms reduce heat dispersion; open forms facilitate ventilation and natural heating of roofs and walls; a building’s orientation must take into account breadth, the transparency of the walls and the need to reflect or allow solar energy to enter. The exchange of heat between the building and atmosphere increases with the velocity of movement of external air. It is therefore necessary to allow the wind to flow when heat needs to be removed, but to impede it in winter to reduce heat loss.
