Nowadays the biomimicry solutions for interior design problems is an obligation rather than a wish to satisfy human needs and quality of human life . In this research study , biomimicry technology is used to formulate a “breathing window" model to enhance the natural ventilation as a way of curing the ecological and sustainable balance by providing social , culture, environment, and  economic progress. The proposed model is based on using the biomimicry approach; “designs looking to biology" to emulate the structure form and function task for chosen natural organisms; Human nose, Bee's honey comb, and Cacti cooling plant. This emulation can be actuated through using different natural phenomena's: evaporative cooling, shading, and changing light to heat, which natural organisms used to adapt themself to the surrounding climate. The “Breathing Window" consists of steps with specific feature and task. In summer: increases shade , reduce heat gain around and on window by reflecting direct sunrays then , cool and filter air flow passing through window using evaporative –cooling phenomena. In winter; it filter air, permits direct sunrays to pass through window, spreading light and heat, in the far  interior  environment .  The “Breathing Window"  adding to cooling interior air in summer and warming it in winter ,filter  air from micro particles and dust , maintain the aesthetic design appearance , reduce: used material , energy , weight ,pollution and cost ,also easy to clean ,well-being of occupant ,and rating sustainability in interior environment .
