Simulation of the thermal behavior of a room by the Green's function method.

The study of the thermal behavior of a building, submitted to variable atmo spheric conditions, demands a study of the heat transfer phenomena in the n onstationary regime. The aim of this study is to evaluate as finely as poss ible the response of the room in the dynamic regime to indicial and harmoni c sollicitations of the external temperatures. We have thus elaborated a ma thematical model based on the Green's function theory for the evidencing of the thermal inertia of the room from the resolution of the equation of hea t propagation in the wall and the equation of thermal equilibrium for the i nternal air of the room.
