Talk Title: Uncertainty Quantification of future energy consumption of buildings

Abstract:
We quantify uncertainties in energy consumption of the built environment using Bayesian approaches and demonstrate examples of recent applications on individual buildings and for an entire population of buildings. We use the Kennedy O’ Hagan framework to calibrate energy models of representative buildings in a city, and argue that this approach is better suited than other existing protocols for evaluating retrofits of existing buildings. We consider alternative techniques, namely, Bayesian regression analysis and inverse methods to evaluate an entire set of buildings in a city. This work is driven by the need to quantify future energy demand of buildings in their urban context as a function of projected growth of buildings and populations, refurbishments, policies incentivizing energy efficiency measures, and changes in building operation.




Biography:
Dr Ruchi Choudhary specializes in building simulation with a particular interest in multicriteria modelling of energy demand and environmental characteristics of the built environment. Choudhary’s research is embedded within a wider multi-disciplinary project called the `Energy Efficient Cities Initiative', in which she leads the work on the built environment. Her recent research focuses on developing tools and methods for analysing energy consumption of large sets of buildings. These have resulted in two parallel investigations: one on how to represent and evaluate relevant and large-scale research and policy questions through physics-based models, and second, how to quantify uncertainties in model outcomes.
