The contemporary demand for reducing carbon emission is changing the way architects design buildings, thus influencing a wide range of new solutions. In this paper, the author presents a method that intends to contribute for the discussion of recent strategies that lower the buildings' consumption of energy. The study establishes three priority parameters to analyze the faqades based on the materials, the practices and the thermal behavior. Each parameter is measured separately scaled from artificial to natural building materials, local to distant practices and insulation to inertia. The design of facades has been evolving to follow complex regulations that aim to increase the required sustainable performance of buildings. Scientific data is measurable individually by each parameter, though the cross influence between parameters raise the level of complexity. Shading systems, solar passive energy influence the measurement but the growing use of renewable energies affects the measurements of energy consumption. Each design responds differently to climatic conditions, and requires complex analyses considering the specificity of the natural environment and cultural context. The discussion makes use of scientific data that influences architectural design, the research requires a broader perception thus including cultural aspects. Recent high tech insulating systems have an effect on design solutions that characterize biophilia (human love of nature). The wisdom of traditional local solutions tested over generations holds cultural aspects of biomimicry (nature as model). The aim is to discuss whether the framework based on biophilia and biomimicry is useful for the research. 展开更多
