Abstract
The building sector accounts for approximately 40% of the world’s energy consumption. With projected increases in global warming, energy dependency, energy reliability, and urban populations, integrated structures are emerging that act as climate filters. To improve the energy efficiency of these systems, it is important to investigate design strategies, such as dialectic form-finding, that have the potential to reduce the energy required for construction materials and for occupants’ thermal comfort. Dialectic form-finding is an extension of the traditional form-finding process and incorporates energy-related design constraints. The resulting integrated systems are both structurally and energy efficient. This paper presents a design and testing approach, based on numerical models and physical prototypes, for two dialectic form-found integrated structures. The first integrated system is a dynamic, adaptive, modular façade system for a building. The façade is a climate filter because it adapts its opacity in response to changing weather conditions. Therefore, the façade reduces energy needs and improves the environmental performance of a building. The kinetics of the composite façade module rely on large elastic deformations and further reduce operational energy by limiting the energy needed for actuation.
