In our buildings, we require a pleasant indoor climate. This necessitates a comfortable temperature, humidity, and air quality. For this, we need the appropriate supply technology with all its machines and systems, which consume a considerable amount of energy. Therefore, the goal in developing climate control systems is to save energy while simultaneously creating a higher level of living comfort. Many interesting ideas can be found in the structures of animals, which exhibit sophisticated solutions for climate control. In line with the principle of "discovering biological phenomena to create natural climate systems and inventing technical solutions based on them," this volume is aimed at a broad readership. The book vividly presents many such solutions from the animal kingdom, showing how they can be translated into technology.
