“…In BPS, UA is an important part of many ongoing research activities. It's use is integrated in several approaches including: parameter screening/ reduction [Alam et al, 2004], metamodelling [Leung et al, 2001], robustness analysis [Topcu et al, 2004;Perry et al, 2008], model validation [Pietrzyk et al, 2008] amongst others. Other approaches in building performance are for instance shown in [Verbeeck et al, 2007] where a methodology is developed to optimize concepts for extremely low energy dwellings.…”

“…In this case a perturbation analysis supports in analyzing the sensitivity for errors and error propagation. Pietrzyk et al [2008] describe reliability in building physics design in terms of the probability of exceeding critical physical values as result of changes in climatic, structural, or serviceability parameters. They provide an example for the influence of air exchange showing the reliability in the design of ventilation.…”

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.

“…size and distribution of enclosure openings) on interacting indoor microenvironments; 5) design and construction deficiencies; and 6) the variability of the renewable energy sources. Acknowledging these uncertainties, Pietrzyk and Hagenhoft [23] propose a reliability-based approach to building science that is used to predict reliable indoor ventilation rates under variable enclosure infiltration scenarios from construction deficiencies. A main challenge in designing sustainable buildings with renewable energy sources is to strive to harmonize the effects of variability described above instead of minimizing these, as is the aim in robust mechanical designs.…”
