Motivated by global climate change, including global warming and greenhouse gas emissions, architects and designers undertook a duty to look for more efficient, sustainable building systems. Among the modern tools used to tackle the building functionality and climate-related problems is biomimicry. Aiming to enhance self-sustainability, widen ecological building elements, and boost building behaviour efficiency, bio-mimicry draws from nature mimicking the life principles of biological role models which have proved to overcome similar challenges; thus, reaching building behaviour’s targets. The paper specifically discusses the embodiment of bio-mimetic strategies into building behaviour elements that increases building behaviour efficiency.
