摘要

PROBLEM TO BE SOLVED: To precisely calculate heat conductivity of each region in a building material.SOLUTION: Measured values of temporal variations in outside surface temperature and inside surface temperature of a building material when an outside surface of the building material is actually heated are acquired, and numeric analysis is taken so as to find heat conductivity of each of layers obtained by dividing a virtual infinite flat plate made of the same material of the building material to the same thickness in a thickness direction. In this numeric analysis, tentative heat conductivity of each layer is set, and a heat conductivity equation is solved using the set tentative heat conductivity and measurement results associated with a temporal variation in outside surface temperature of the building material so as to calculate a temporal variation in temperature of an inside surface of the infinite flat plate. Tentative heat conductivity so set that the calculated temporal variation in temperature of the inside surface of the infinite flat plate matches a measurement result associated with the temporal variation in inside surface temperature of the building material is stored in a storage part as heat conductivity of each layer.SELECTED DRAWING: Figure 4
