The paper discusses a methodology for thermal analysis applied to buildings in which the stochasticnature of the external forces is concerned. The considered forces are ambient temperature and solarradiation. The stochastic approach presented in this paper, consists in modelling the climatic inputs as a Markov process which have been injected on a reduced modal model describing the thermalbehaviour of the building. The weather records used for stochastic identification have been gathered over 5-years (1975-1979) in Tunis and the case study has been carried on a typical Tunisian building.As a result of numerical computation, the distribution of indoor temperature has been directly obtained, as well as that of the comfort index of the building.
