“…By means of evaporation, the system provides a cooling effect due to latent heat transfer. Bio Skin's goal not only is to reduce cooling load of the building, but also to act as a mitigation strategy for the urban heat island effect by cooling the surrounding air (Yamanashi and Hatori 2011). The internal vascular networks, found in most homeothermic living organisms, form the basis for an innovative adaptive window system, developed at the Wyss Institute for Biologically Inspired Engineering at Harvard University (Hatton et al 2013).…”

How do living organisms capture, convert, store and process energy, water and sunlight? How does nature cool down, heat up, provide shade, and control light? Adaptability, the ability of a system to act in response to variations in environmental conditions often plays a key role in this context. Unlike living organisms, buildings are typically conceived as static, inanimate objects. Because a building's surroundings and internal conditions are constantly changing, there is a lot to learn about how inspiration from nature can foster more adaptability of the façade for enhanced building performance. After highlighting the need for more adaptability in the built environment, this chapter reviews state-of-the-art examples of research concepts and design applications with bio-inspired adaptable solutions for the building envelope. All examples are in the scope of building physics and energy efficiency with a focus on improving indoor environmental quality. The chapter concludes with an outlook of design support methodologies that can potentially incite the practical uptake of bio-inspired adaptive building skins in the future.

“…Other representative cases of this approach are the thermo-activated envelope systems. An innovative louver system called BioSkin of The Sony City Osaki building (Yamanashi 2011) used evaporative cooling technology, which adds the cooling impact on the envelope by dropping the ambient surface temperature to reduce convective heat gain on the envelope. The inflatable ETFE skin of Media-TIC in Barcelona, which has dot patterns on both the inner and outer layers of the ETFE designed to cover a specific range of the surface to control incident solar radiation, can add an improved insulation value while controlling the amount of solar insolation depending on the change in climate conditions (Juaristi 2016) .…”

The built environment is responsible for nearly 40% of global energy use, significantly contributing to carbon emissions. Targeting a carbon-negative future would require a rethinking of the way we heat and cool buildings, distancing ourselves from the predominant model for the building envelope as a boundary that excludes the weather and instead adopting alternatives that transform the building envelope to a mediator that actively regulates heat exchange. In this paper, we explore the potential for a building boundary that actively heats and cools a building by forming dynamic relationships with surroundings. Most decarbonizing efforts today focus on realizing net-zero operational carbon either via the production and distribution of renewable energy or via passive house strategies that target the reduction of the active energy demand. We propose a third alternative. Instead of an endothermic model for heating and cooling in which energy is brought in the interior, transformed by a mechanical system and then distributed, we propose an ectothermic envelope system that dynamically forms a relationship with its environment, by choosing to absorb or release heat directly from or to the environment. From a design perspective, we will show a modular building energy system, comprised of a double hydronic heating and cooling layer. In essence, we are developing for a building, the equivalent to a vascular system that can move liquids at different locations to thermo-regulate. We will show how this vascular system can use ambient heat as heating and cooling sources for a building. From a more technical perspective, since all simulation tools available today assume an endothermic approach, we will show an alternative using Modelica and co-simulation for simulating an ectothermic approach. We are developing a weather chamber, which can generate an artificial version of the weather from data to test how our system would dynamically respond.

“…The area of the Sony forest spreads over some 6,000 m2 surrounding a new Sony office building site, located in a redeveloped area near Osaki Station,Tokyo, Japan.The new office building was designed by Tomohiko Yamanashi, who introduced a facade system called the Bio Skin developed by Nikken Sekkei and TOTO [21].The Bio Skin is made of ceramic panels in which water pipes are embedded, and water flowing through the pipes reduces the heat generated by sunlight.The project site is located on a gently rolling hill with a 10 m change in altitude.The aim of our project was to create a 'natural forest' around the Sony building by using the SS system to design the forest. In the next section, we describe the functions of the SS system together with the design process of the Sony forest project.…”

This paper proposes a computational landscape design method, called the Seeds Scattering system (SS system), that was developed by the AnS Studio to carry out the Sony forest project in Japan. This method enables us to manage various environmental conditions in design processes, to design ‘natural’ in urban areas, (i.e., people perceive a forest in an urbanized area as if it is natural although the forest is not genuinely natural). First, this paper discusses the limitations of the conventional method of landscape design. In Section 3 to 4, we describes the SS system together with the design process of the project. In Section 5, we present the system from a different perspective, that is, as a method for satisfying social requirements to gain human appreciation. The designer's role in this system is not to manipulate geometries or compositions of tree groupings but to design the fundamental rules that underlie them. As a result, the designer can create a landscape in an interactive manner, thereby producing one that inherently belongs to its site.
