“On Fluctuation” explores how material behaviour can support more climate-responsive public interiors. This degree project investigates phase-change materials (PCMs) as a passive method for moderating indoor temperatures, focusing on their ability to absorb and release heat through natural melt–freeze cycles. Through research, prototyping, and testing, the work develops a hanging artefact that responds to temperature variation in shared interior environments.

The artefact integrates salt hydrate PCMs within a modular, temperature-responsive design that becomes visually and thermally active as conditions change. By engaging with both environmental performance and spatial expression, the project positions thermal regulation not only as a technical challenge but as a design opportunity.

“On Fluctuation” proposes an alternative approach to indoor comfort in public buildings, demonstrating how material driven design can reduce reliance on mechanical systems while enriching the atmospheric qualities of shared interior environments.
