“…The identification process begins with the exploration model considering heat regulation as a primary problem as the methodology proposed in [ 18 ]. Thus, the biomimetic design is based on four initial functions: gain, dissipate, transfer, and prevent ( Figure 4 ).…”

In recent years, demographic growth has caused cities to expand their urban areas, increasing the risk of overheating, creating insurmountable microclimatic conditions within the urban area, which is why studies have been carried out on the urban heat island effect (UHI) and its mitigation. Therefore, this research aims to evaluate the cooling potential in the application of strategies based on biomimicry for the microclimate in a historical heritage city of Panama. For this, three case studies (base case, case 1, and case 2) of outdoor thermal comfort were evaluated, in which the Envi-met software was used to emulate and evaluate the thermal performance of these strategies during March (highest temperature month) and October (rainier month). The strategies used were extracted from the contrast of zebra skin, human skin, evaporative cooling, and ant skin. The results showed a reduction of 2.8 °C in the air temperature at 11:00, the radiant temperature decreased by 2.2 °C, and the PET index managed to reduce the thermal comfort indicator among its categories. The importance of thinking based on biomimicry in sustainable strategies is concluded; although significant changes were obtained, high risks of discomfort persist due to the layout and proximity of the building.

“…Beyond generating heat metabolically, heat is transferred between animals and their environment by conduction, convection, radiation, and evaporation. These processes are carried out by organisms and/or employed in their built structures to gain, retain, dissipate, and prevent heat [67]. For example, termite mounds dissipate heat via natural convection [68], and toucans dissipate heat via radiation emission [69].…”

Building envelopes represent the interface between the outdoor environment and the indoor occupied spaces. They are often considered as barriers and shields, limiting solutions that adapt to environmental changes. Nature provides a large database of adaptation strategies that can be implemented in design in general, and in the design of building envelopes in particular. Biomimetics, where solutions are obtained by emulating strategies from nature, is a rapidly growing design discipline in engineering, and an emerging field in architecture. This paper presents a biomimetic approach to facilitate the generation of design concepts, and enhance the development of building envelopes that are better suited to their environments. Morphology plays a significant role in the way systems adapt to environmental conditions, and provides a multi-functional interface to regulate heat, air, water, and light. In this work, we emphasize the functional role of morphology for environmental adaptation, where distinct morphologies, corresponding processes, their underlying mechanisms, and potential applications to buildings are distinguished. Emphasizing this morphological contribution to environmental adaptation would enable designers to apply a proper morphology for a desired environmental process, hence promoting the development of adaptive solutions for building envelopes.

“…The human body functions in a dynamic equilibrium with an ever‐changing external environment, ensuring a relative constancy of its internal environment through a set of tightly controlled, negative‐feedback‐based processes collectively termed homeostasis (Modell et al, 2015). As an example, certain animals, especially those who live in extreme conditions, have evolved special adaptations which humans nowadays try to mimic in their inventions (i.e., biomimetics, bionics) (Badarnah, 2015; McCafferty, Pandraud, Gilles, Fabra‐Puchol, & Henry, 2017; Si et al, 2015; Tao et al, 2015). From a medical viewpoint, the dysregulation of this homeostasis can have grave consequences and ultimately lead to death (Cheshire Jr., 2016; Walter, Hanna‐Jumma, Carraretto, & Forni, 2016).…”

Thermoregulation plays a vital role in homeostasis. Many species of animals as well as humans have evolved various physiological mechanisms for body temperature control, which are characteristically flexible and enable a fine‐tuned spatial and temporal regulation of body temperature in different environmental conditions and circumstances. Human beings normally maintain a core body temperature at around 37°C, and maintenance of this relatively high temperature is critical for survival. Therefore, principles of thermoregulatory control have also important clinical implications. Infections can cause the body temperature to rise internally and several diseases can cause a dysfunction of thermoregulatory mechanisms. Moreover, the utilization of thermotherapies in treating various diseases has been known for thousands of years with a recent resurgence of interest. An increasing amount of research suggests that targeted temperature management is of paramount importance to patient outcomes in certain clinical scenarios. We provide a concise summary of the basic concepts of thermoregulation. Emphasis is given to the principles of thermoregulation in humans in basic pathological states and to targeted temperature management strategies in the clinical environment, with special attention on therapeutic hypothermia in postcardiac arrest patients. Finally, the discussion is focused on the potential offered by computational thermophysiological models for predicting thermal responses of patients in various clinical circumstances, for proposing new perspectives in the design of novel thermal therapies, and to optimize targeted temperature management strategies.This article is categorized under: Cardiovascular Diseases > Computational Models Cardiovascular Diseases > Environmental Factors Cardiovascular Diseases > Biomedical Engineering
