“…A further development of the inverse approach is presented by Kasinalis et al [27]. In this work the authors' main objective is to identify the optimal properties of an opaque façade and the optimal WWR by means of a multi-objective optimisation approach.…”

“…These approaches have been applied to evaluate one or multiple optimal building envelope adaptive properties as follows: one optical property of the transparent part [15,21,22] or one thermal property of the opaque part [23][24][25] of the building envelope at the time; the Window to Wall Ratio (WWR) [26]; multiple properties of the building envelope simultaneously [27][28][29][30]. These studies can be classified into theoretical [15,21], direct [22] and inverse approaches [23][24][25][26][27][28][29][30].…”

“…A similar approach is adopted by Favoino et al [28,30] to optimise long-term adaptive glazing properties; while the same inverse approach is extending to shorter adaptiveness of the façade (from months to hours) by Goia and Cascone [26], to optimise the WWR, and by Martinez [29], to optimise different hourly adaptive façade properties simultaneously. In these studies [26][27][28][29][30] the adaptive façade behaviour is approximated as the sum of the performance of different static façades for the relevant sub-annual time horizons. Though this cannot be considered always correct, in fact the effect of varying material properties at a certain time can affect the energy transfer through the building envelope and the energy balance of the indoor environment with a certain delay (hours or days), depending on the thermal inertia of the building.…”

a b s t r a c tThe development of dynamic building envelope technologies, which adapt to changing outdoor and indoor environments, is considered a crucial step towards the achievement of the nearly Zero Energy Building target. It is currently not possible to evaluate the energy saving potential of innovative adaptive transparent building envelopes in an accurate manner. This creates difficulties in selecting between competing technologies and is a barrier to systematic development of these innovative technologies.The main aim of this work is to develop a method for devising optimal adaptive glazing properties and to evaluate the energy saving potential resulting from the adoption of such a technology. The method makes use of an inverse performance-oriented approach, to minimize the total primary energy use of a building. It is applied to multiple case studies (office reference room with 4 different cardinal orientations and in three different temperate climates) in order to evaluate and optimise the performance of adaptive glazing as it responds to changing boundary conditions on a monthly and daily basis. A frequency analysis on the set of optimised adaptive properties is subsequently performed to identify salient features of ideal adaptive glazing.The results show that high energy savings are achievable by adapting the transparent part of the building envelope alone, the largest component being the cooling energy demand. As expected, the energy savings are highly sensitive to: the time scale of the adaptive mechanisms; the capability of the façade to adapt to the outdoor climatic condition; the difference between outdoor climatic condition and the comfort range. Moreover important features of the optimal thermo-optical properties are identified. Of these, one of the most important findings is that a unique optimised technology, varying its thermo-optical properties between a limited number of states could be effective in different climates and orientations.

“…Some authors optimised the thermo-physical properties [13,14] or insulation thickness [15][16][17][18][19] of the opaque envelope. Other researches studied optimal Window-to-Wall Ratio (WWR) configurations [20,21] or combined an optimisation of thermo-physical properties and WWR [12,[22][23][24][25]. Several researches focused on the optimisation of shading devices [26,27] or the combination of shading device and window area [28].…”

“…Natural envelope-like structures such as shells, skins and coverings have evolved over time to limit energy expenditure while maintaining conditions to thrive and reproduce. In many instances, adaptability, either on the short-or longerterm (Kasinalis et al 2014), forms an essential mechanism for resilience and survival. Mimicking these strategies, by finding functional analogies, and bringing them to the domain of architecture, can form a key ingredient for environmentally conscious sustainable development in the building sector.…”

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.
