Abstract

Behaviour of a rock as a barrier of heat differs so much from the behaviour of a conventional insulator. In thecase of an insulator the factor that governs the heat exchange is Thermal Conductivity. But rocks, being massive in both density and scale, the Heat Capacity of the material largely effect the heat flow. And under natural thermal environment, the heat flow will never reach a steady state. The governing factor of heat flow here is Thermal Diffusivity. This ever-transient heat flow problem is so complex that it is hardly studied. This report is the forerunner to a research or the capability to utilize natural rock for motions in architecture to create advanced thermal environment. The main objective is to verify whether rocks do effect the thermal environment of their surrounding to a level worthwhile to be studied.
