Paulownia Wood for Thermal Adaptive Architecture

This research investigates a thermally adaptive architecture for hot climates. This is done by the use of Paulownia, a low-density, fast-growing wood species. The strategy is based on the development of locally grown CO2 sequestering materials, thermally open and adaptive elements and spaces, for a
modular and poetic architecture in climates with rising and unstable thermal conditions. The idea and strategy differ from the dominating solutions in the Mediterranean region, traditionally focused on heavy structures, excavated mineral-based materials, and enclosed spaces with air-conditioning
systems. Through material, geometry and full-scale construction methods, the project examines, tests and documents the spatio-temporal and thermal adaptive capacities in a completed test house in the
region of Valencia, Spain. Material and environmental sensors are mounted in the test house for analysis between seconds and weeks. Along with the data collection from sensors, the test house modular operable elements are qualitatively evaluated for the ability to construct microclimates for
occupant preferences of temperature, light, and space across time and use. The sensor-based environmental dataset is furthermore used to calculate the thermal sensation using heat balance and adaptive comfort theories and models. The results from the test house as a modular, low-density, thermally adaptive free-running living unit and the calculated thermal sensations based on this strategy
reveal that thermal comfort is reachable, albeit it demands engagement and active personal adaption from occupants.
