A comparative study on uncertainty propagation in high performance building design

In this paper, analysis is performed on the uncer-tainty in energy consumption calculated from whole-building energy models of two different building de-signs; a typical code compliant building, and the same building redesigned with high performance elements. We perform sensitivity analysis which reveals which parameters (out of approximately 900) influence the uncertainty in the consumption of energy in the build-ing model the most. We conclude that the most sensi-tive parameters of the model relate to building opera-tion (i.e. scheduling), and also find that a low energy building design is more robust to parameter variations than the conventional design.
