Contribution to the Stochastic Simulation of Buildings Thermal Behaviour

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.
