“…They provide an example for the influence of air exchange showing the reliability in the design of ventilation. Marques et al [2005] for instance evaluate the reliability of passive systems by first identifying the sources of uncertainties and the determination of the important variables. Secondly, the uncertainties are propagated through a response surface.…”

Building Performance Simulation (BPS) has the potential to provide relevant design information by indicating directions for design solutions or uncertainty and sensitivity analysis. A major challenge in simulation tools is how to deal with difficulties through large variety of parameters and complexity of factors such as non-linearity, discreteness, and uncertainty. It is hypothesized that conducting an uncertainty and sensitivity analysis throughout key stages of the design process would be of great importance. The purpose of uncertainty and sensitivity analysis can be described as identifying uncertainties in input and output of a system or simulation tool [Lomas, 1992; Fuerbringer, 1994;MacDonald, 2002]. In practice uncertainty and sensitivity analysis have many additional benefits including:(1) With the help of parameter screening it enables the simplification of a model [de Wit, 1997].(2) It allows the analysis of the robustness of a model [Litko, 2005]. (3) It makes aware of unexpected sensitivities that may lead to errors and/ or wrong specifications (quality assurance) [Lewandowska et al., 2004; Hopfe et al., 2006;Hopfe et al., 2007] (4) By changing the input of the parameters and showing the effect on the outcome of a model, it provides a "what-if analysis". It is for instance used in multiple decision support tools [Gokhale, 2009].In this paper a case study is performed based on an office building with respect to various building performance parameters. Uncertainty analysis (UA) is carried out and implications for the results considering energy consumption (annual heating and cooling) and thermal comfort (weighted over-and underheating hours) are demonstrated and elaborated. The added value and usefulness of the integration of UA in BPS is shown.

“…The reliability analysis of passive safety systems of advanced Nuclear Power Plants (NPPs) must consider that when uncertainties of counter-forces (e.g., friction) have magnitude comparable to the driving ones (e.g., gravity, natural circulation), physical phenomena may fail performing the intended function even if i) safety margins are met, ii) no hardware failures occur (Marques et al 2005, Burgazzi 2007, Zio et al 2009). …”

“…To quantify the reliability of passive safety systems the concept of functional failure has been introduced [Cummins et al 2003] [Pagani et al 2005] [Burgazzi et al 2007] [Zio et al 2009]: when counter-forces (e.g., friction) have magnitude comparable to the driving ones (e.g., gravity, natural circulation), the passive systems may fail performing the intended functions even if i) safety margins are met, ii) no hardware failures occur [Burgazzi 2004] [Marques et al 2005] [Burgazzi 2007b] [Zio et al 2009]. …”
