At present, buildings are increasingly being designed with transparent materials, with glass paneling being especially popular as an installation material due to its architectural allure. However, its major drawback is admitting impractical amounts of sunlight into interior spaces. Office buildings with excessive sunlight in indoor areas lead to worker inefficiency. This article studied kinetic façades as means to provide suitable sunlight for interior spaces, integrated with a triple-identity DNA structure, photosynthetic behavior, and the twist, which was divided into generation and evaluation. The generating phase first used an evolutionary engine to produce potential strip patterns. The kinetic façade was subsequently evaluated using the Climate Studio software to validate daylight admission in an indoor space with Leadership in Energy and Environmental Design (LEED) version 4.1 criteria. To analyze the kinetic façade system, the building envelope was divided into four types: glass panel, static façade, rotating façade (the kinetic façade, version 1); an existing kinetic façade that is commonly seen in the market, and twisting façade (the kinetic façade, version 2); the kinetic façade that uses the process to invent the new identity of the façade. In addition, for both the rotating façade and twisting façade, the degrees of simulation were 20, 50, 80, and 100 degrees, in order to ascertain the potential for both façades to the same degree. Comparing all façades receiving the daylight factor (DF) into the space with more or less sunlight resulted in a decreasing order of potential, as follows: entirely glass façade, twisting façade (the kinetic façade, version 2), rotating façade (the kinetic façade, version 1), and static façade. By receiving the daylight factor (DF), the façade moderately and beneficially filtered appropriate amounts of daylight into the working space. The daylight simulation results indicated that the newly designed kinetic façade (version 2) had more potential than other building envelope types in terms of filtering beneficial daylight in indoor areas. This article also experimented with the kinetic façade prototype in an actual situation to test conditional environmental potential. The twisting façade (the kinetic façade, version 2) was explored in the building envelope with varied adaptability to provide sunlight and for private-to-public, public-to-private, or semi-public working areas.

In light of pressing global health concerns, the significance of indoor air quality in densely populated structures has been emphasized. This research introduces the Mimosa kinetic façade, an innovative design inspired by the adaptive responsiveness of the Mimosa plant to environmental stimuli. Traditional static architectural façades often hinder natural ventilation, leading to diminished air quality with potential health and cognitive repercussions. The Mimosa kinetic façade addresses these challenges by enhancing effective airflow and facilitating the removal of airborne contaminants. This study evaluates the façade’s impact on quality of life and its aesthetic contribution to architectural beauty, utilizing the biomimicry design spiral for a nature-inspired approach. Computational simulations and physical tests were conducted to assess the ventilation capacities of various façade systems, with a particular focus on settings in Bangkok, Thailand. The study revealed that kinetic façades, especially certain patterns, provided superior ventilation compared to static ones. Some patterns prioritized ventilation, while others optimized human comfort during extended stays. Notably, the most effective patterns of the kinetic façade inspired by the Mimosa demonstrated a high air velocity reaching up to 12 m/s, in contrast to the peak of 2.50 m/s in single-sided façades (traditional façades). This highlights the kinetic façade’s potential to rapidly expel airborne particles from indoor spaces, outperforming traditional façades. The findings underscore the potential of specific kinetic façade patterns in enhancing indoor air quality and human comfort, indicating a promising future for kinetic façades in architectural design. This study aims to achieve an optimal balance between indoor air quality and human comfort, although challenges remain in perfecting this equilibrium.

Today, buildings are increasingly designed with transparent materials, with glass paneling being especially popular as an installation material for its architectural allure. However, its major drawback is admitting impractical amounts of sunlight to interior spaces. Office buildings with excessive sunlight in indoor areas result in worker inefficiency. This article studied kinetic façades as means to providing suitable sunlight for interior spaces integrated with a triple identity of DNA structure, photosynthetic behavior, and the twist used, which was divided into generation and evaluation. The generating phase first used an evolutionary engine to produce potential strip patterns. The kinetic façade was subsequently evaluated by Climate Studio software to validate daylight admission in an indoor space with Leadership in Energy and Environmental Design (LEED) version 4.1 criteria. To analyze the kinetic façade system, the building envelope was divided into four types: glass panels, static façades, kinetic façade (version 1, rotating movement), and kinetic façades (version 2, twisting movement). In addition, for kinetic façades, degrees of simulation for versions 1 and 2 were 20, 50, 80, and 100 degrees, in order to ascertain potential for both façades to the same degree. Comparing all façades receiving the daylight factor (DF) into the space from more or less sunlight resulted in the decreasing order of potential as follows: entirely glass façade, kinetic façade version 2, kinetic façade version 1, and static façade. By receiving daylight factor (DF), the façade filtered appropriate amounts of daylight into the working space moderately and beneficially. Daylight simulation results indicated that the newly designed kinetic façade (version 2) had more potential than other building envelope types in terms of filtering beneficial daylight in indoor areas. This article also experimented with the kinetic façade prototype in an actual situation to test conditional environmental potential. The kinetic façade (version 2) was explored in the building envelope with varied adaptability in order to provide sunlight and for private-to-public, public-to-private, or semi-public working areas.

The increasingly popular design trend of glazed facades using daylight in buildings has made it essential for innovations to eliminate the unnecessary intrusion of sunlight in spaces. This study aims to create a kinetic façade pattern by referring DNA structure and photosynthetic behaviour to mimic biomimicry science characteristics in Wallacei evolutionary software for generating possible patterns. Daylight glare thresholds were determined as an essential factor for user productive work. Comparison of three-building envelope potential was made for preparing spaces (zones A, B) in Bangkok condition; without a façade, with a static facade, and with a kinetic façade. DIVA software was used to analyse glare in terms of daylight glare probability (DGP). First, DGP (without façade) for zones A and B were 100% and 55%, or intolerable glare. Second, DGP (static façade) for zones A and B were 59%, 30%; zone A was intolerable, and B imperceptible. Third, DGP (kinetic façade) for zones A and B were 28% (imperceptible glare). Therefore, a kinetic façade has a high potential for protecting against unsuitable glare. These findings may serve as preliminary evidence for understanding kinetic façade potential for self-adjustment by light intensity to improve quality of life for occupant use of spaces.

This research focuses on interpreting the Eshelby twist behavior into kinetic façade design, which is a continuous crystallographic twist generated by the torsional force of an axial screw dislocation in a one-dimensional nanowire structure. The mechanism can be adjusted to the kinetic façade, changing dynamically rather than being static or fixed and allowing movement to occur on a building's surface with the potential to reduce sunlight exposure. Natural light is essential for making human work in building spaces more productive. The solution to the issue of inappropriate natural light in indoor spaces is a kinetic façade, which is self-adjustable according to sunlight intensity. The simulation results before and after installing the façade show the sunlight exposure value were 2030 kWh/m ² and 300 kWh/m ² per year, respectively. 2030 kWh/m ² , this value is too excessive for direct sunlight for users living in the space. As a result, the sunlight exposure value after installation is acceptable for users; it is verified that the proposed design can strongly decrease sunlight exposure. These findings indicate that the Eshelby twist is the principal phenomenon facilitating façade movement.
