A COMPARATIVE STUDY ON UNCERTAINTY PROPAGATION IN HIGH PERFORMANCE BUILDING DESIGN

In this paper, analysis is performed on the uncertainty in energy consumption calculated from wholebuilding energy models of two different building designs; 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 building model the most. We conclude that the most sensitive parameters of the model relate to building operation (i.e. scheduling), and also find that a low energy building design is more robust to parameter variations than the conventional design.
