Researching Neural Earthen Architecture / Case Study at CAA - BfNA

Half over water earthen meditation sphere / CSEB mass for the 33 m dome, acoustic resonators, walking and contemplative attention as neural-environmental infrastructure

[Summary]

Developed and presented at the China Academy of Art, Hangzhou, 2026, as part of a collaborative teaching programme with the Auroville Earth Institute. Drawing on publicly available architectural documentation and materials shared during the teaching programme. This independent research examines the relationships between earthen architecture, embodied cognition, spatial perception and contemplative experience.

Autonomic regulation · Attention · Interoception · Sensory modulation

[Description]

Shree Krishnaganga Meditation Hall, Gujarat. The 33 m diameter hemispherical earthen structurer is examined as a neural-environmental system rather than a monumental object. Its half-spherical water body, CSEB mass, large-span curvature, acoustic resonator strategy, walking condition around/above water and contemplative programme combine thermal inertia, reflection, sound, breath, balance and attentional regulation. The case study allows BfNA to investigate how water, earth, resonance, movement and meditation may contribute to embodied cognition, sensory regulation and contemplative experience.

[Neural Analysis]

WATER, RESONANCE AND ATTENTION: The 33 m Gujarat sphere combines CSEB mass, water, curvature and acoustic tuning into one contemplative field. The water body is not decorative: it changes reflection, thermal behaviour, movement, depth perception and bodily orientation. Walking and meditation above/around water introduce vestibular, auditory and interoceptive modulation, while the structure's earthen mass and resonators frame attention through low-frequency control, breath rhythm and collective stillness. The proposed neural and physiological relationships constitute research hypotheses informed by existing scientific literature; they have not been empirically measured or validated in this architectural setting.

EARTH + WATER + ACOUSTIC REGULATION [A3][B1][T2][S2]: The neural reading connects water-mediated reflection, slow walking, vestibular balance, acoustic resonance, breath rhythm and interoception. The dome's 2,200-tonne CSEB mass provides thermal and tactile continuity; the water body introduces reflective discontinuity; the acoustic resonators address frequencies from 80 Hz to 1214 Hz. This makes the building an instrument for studying contemplative attention through material, hydrological and sonic conditions.

[Social Impact]

SOCIAL: The sphere supports collective meditation through low-carbon material intelligence, acoustic care, shared ritual and a spatial relationship between body, water and earth.

[ROI Sustainability]

ROI: Long-span earthen construction demonstrates cultural, climatic, acoustic and educational value beyond conventional concrete monumentality.

ROI: The dome's value is technical and cultural: 297,560 blocks, 115 days of construction, acoustic tuning and water-based spatial experience create a demonstrator for future earthen contemplative environments.

[Applied R&D Lens]

Measure reverberation, frequency absorption, thermal lag, walking rhythm, water-reflection perception, breath rhythm and self-reported attentional depth during contemplative use.

Develop a water-earth-sound research protocol: compare dry and water-reflective zones, walking routes, acoustic positions and meditation durations against attention, interoception and autonomic markers.
