Reliability based design optimization of insulation systems considering climate change and workmanship uncertainties Aïssani, Amina; Chateauneuf, Alaa; Fontaine, Jean-Pierre


Today, the political and regulatory framework related to the building sector is more demanding as it remains the principal source of air pollution leading to global warming. Therefore, it is important to have a better control on the energetic performance of the building envelope in order to control the consumption. This paper presents a methodology allowing us to obtain optimal designs of the envelope considering different kinds of uncertainties mainly those related to climate changes, material deterioration and man-made defects. The time-dependent uncertainties are considered as random processes while the time-invariant variability related to defects is considered as random variable. The results show the impact of considering these uncertainties on the long term reliability of the system and give different optimal designs according to the considered climatic scenario.
