Designing buildings that adapt to the local climate to minimize energy expenses and resources used, avoiding leakage and waste. Control and intelligent use of space. Buildings and their rooms should be appropriately sized to optimize energy use. Sustainable materials such as wood, stone, natural fibers and recycled materials minimize the impact of the building. The energy sector being the most important emitter of these gases worldwide, several countries have reinforced the priority given to energy efficiency and the use of renewable energies through the implementation of policies adapted to their economic, social and climatic specificities. Architectural design is a fundamental step in the creation and production of the building envelope; it is also a very complex step due to its hyper-interested aspects. Upstream, this phase has a considerable influence on several parameters: electrical, thermal, energetic and more globally environmental. Is it possible to create environmentally friendly buildings from the drawing board? The answer is "yes", using what is called bioclimatic architecture with organic and local materials.
