The Breathing Staircase: Designing Thermal Alliesthesia and Responsive Environmental Experiences in Vertical Circulation Spaces

This research explores how thermal alliesthesia, environmental psychology, and adaptive building systems can transform architectural circulation spaces into dynamic sensory environments. Using the staircase of Perloff Hall at UCLA as a case study, the project investigates how controlled thermal transitions, airflow dynamics, lighting conditions, and responsive environmental controls can enhance thermal pleasure, occupant well-being, and spatial engagement. Drawing from research in thermal comfort, human physiology, cognitive psychology, and smart building technologies, the study proposes a responsive staircase that adapts to occupants' changing thermal needs through sensors, airflow modulation, and environmental feedback systems. The project reimagines staircases not as passive circulation elements but as active thermal transition spaces that contribute to memorable and pleasurable architectural experiences.
