Thermal Mass Regulation in Rajasthan’s Stepwell Ceremonies During Summer Solstice

Thermal Mass Regulation in Rajasthan’s Stepwell Ceremonies During Summer Solstice

拉贾斯坦邦阶梯井夏至仪式中的热质量调控

  1. Rajasthan’s Chand Baori stepwell leverages 3,500 m² of sandstone thermal mass to maintain 12°C internal stability amid 48°C surface extremes during solstice rites.
  2. Priests conduct dawn water offerings only when infrared thermography confirms sub-22°C microclimate convergence at the 8th descending level.
  3. The stepped geometry creates laminar air stratification zones, enabling ritual participants to occupy distinct thermal bands without mechanical HVAC intervention.
  4. Local weavers embed phase-change clay pellets into ceremonial shawls, absorbing latent heat during descent and releasing it during ascent rituals.
  5. Water temperature gradients across the well’s depth serve as passive thermometers guiding timing of mantra recitations and oil lamp placements.
  6. This architecture-as-climate-instrument model challenges Western assumptions about ritual space requiring active environmental control systems.
