“…In hot humid climates, the late hours of the nights and the early mornings can be experienced as comfortable, both outdoors and indoors, or even as chilly, apparently reflecting their acclimatization to the local climate [1] [17]. But in the daytime, it has become a level that exceeds the human threshold of indoor thermal comfort [28].…”

Warming ambient climates in hot -warm climates causes a boost of internal air temperature during the daytime, creating uncomfortable thermal circumstances which affect human physical and mental wellbeing. Modifying indoor thermal discomfort into a comfortable condition is promising with thoughtful material usage, architectural and engineering interventions that involve 'passive mode'. The use of layered facade interventions is such a popular passive cooling approach which is proven successful but leftover a few drawbacks in its practical usage. The research involved developing a clay panel to be applied as a secondary skin, which is thin, lightweight, easily removable, and maintainable, evading the hitches and accelerating indoor heat absorption, further becoming an ultimate eco-friendly low cost, low embedded energy solution. The research methodology involved identifying the material's best mix proportion for optimum air permeability, the simplest practical casting method of the panel, identifying optimum configurations on panel's selfcooling, the best firing temperature, and the firing time, etc. Analysis of the results proves the invention's capability in heat absorption, thus reducing the indoor air temperature. With the uncomplicated technologies in the invention, it provides opportunity even for layman in production. Further, the invention has possibilities in playing a vital role in socio-cultural aspects in the field of construction as well.
