Sun Protection

The longest axis of buildings should be oriented east-west, to provide optimal shade. The openings leading to east and west should be kept to a minimum in order to reduce heat input in the early morning and late afternoon.

Natural Ventilaton

Builders who reconnect with those ancestral techniques take advantage of possibilities of the climate and the immediate environment to meet the needs of renewal of air and comfort in a building. There are 2 good reasons for ventilate (health and thermal comfort), 3 ways to cool buildings (direct overventilation, delayed overventilation and air movement) and 4 technical and architectural types (through ventilation, mono-oriented, by draft thermal or assisted and controlled).
