Performative Threshold

Threshold is defined by Limen as transitional between two fixed states in cultural rites of passage or between two dissimilar spaces in architecture. The study of rites of passage provides an analogy from which principles can be drawn for the design of a transformative space. The experience of liminal space poses a discontinuity and leads the occupant to question their surroundings, thus leading to heightened awareness of the space as a transformative threshold between distinct spaces. All buildings have in-between space, the quality of life is directly affected by these spaces. The way of using space cannot be changed as long as architectural space is designed by its form, materials, details, and joints therefore the threshold becomes the key elements that defines the architecture. Façade is exterior of the threshold that protecting environment inside. However with today’s advanced technologies and materials, we can design performative façade system that can create different yet comfortable space for people inside. The threshold of inside and outside can be integrated through performative façade system to control heating and cooling, energy generation or other sustainable system through understanding architecture and movement. High performance building integrates and optimize high performance building criteria that involves with energy efficiency, durability, life-cycle performance, and occupant productivity. This term became important as modern architecture design become more sustainable. As architects explore sustainable design in architecture, performative façade system work efficiently in saving energy consumption. Therefore the research started with 3 different case study involve with performative façade, first one was active surface which is deployable structure base façade that change shapes to create comfort area for people with different experience to people by dynamic movement of its nature. Second version of research is response surface, it evolving measures actual environmental conditions to enable building to adapt their form, shape, color or character responsively. This responsive system creates aesthetic quality to building to changes the experience of architecture that static form cannot not give. Third version is environmentally adaptive, this system changes surface by environmental changes. Instinct change of surface or shell will manage building better to increase life-cycle of building by protecting the structure. Exploring Threshold will be measured by 3 different key elements which include energy and emission, adaptation, and resilience. The performative design will reduce or possibly produce no carbon dioxide emissions in building operations and minimize embodied carbon for building materials and construction. Research and exploring performative façade will project and respond to climate changes, such as responsive to climate changes, heat effect, heat waves, and extreme weather conditions. These factors will be considered in project site and context. Resilience enable continued habitability and rapid recovery unexpected events, natural disaster, absence of power, or other projected climate interruptions.
