Abstract
Paper presented at the XXXIII IAHS World Congress on Housing, 27-30 September 2005,"Transforming Housing Environments through Design", University of Pretoria.
The two main advantages deriving from the insertion of Phase Change Materials (PCM) inside the external envelopes of buildings are lowering temperature peaks in internal environments and shifting their occurrence in time. In this contribution the data collected from a three-month experimental campaign are elaborated through a time series model with conditional heteroskedasticity, for the evaluation of the positive effects deriving from the insertion of a PCM layer in standard stratifications of dry assembled lightweight walls. In this work the performances of two different PCM containing stratifications are compared with the ones of a standard dry assembled lightweight wall. The statistical model in this paper is able of interpreting the long memory effects that affect the temperature time series of the experimental walls, even if with the use of a small number of parameters.
