Developing a Data-Driven Framework for MultiScale Integrated Urban Building and Transportation Energy Modeling
Abstract
This article proposes an integrated data-driven framework for urban energy use modeling (UEUM) that enables providing a holistic image of urban energy use at multiple scales. The UEUM allows aggregating across end-uses, building, and transportation. With considering urban socio-spatial context, it gives insight into the multifaceted and intricate relationships between urban key attributes, and building and transportation energy performance. This model helps predict urban energy performance more precisely by reducing the simulation uncertainties through using disaggregated and spatially explicit data and applying artificial intelligence (AI) techniques. In addition to increasing the accuracy, the model facilitates reducing the execution time for an urban scale energy modeling. The framework was evaluated using Chicago, Illinois, a major city in the US, as a case study. The results for Chicago demonstrate the feasibility of this approach. Among the tested AI algorithms, k-nearest neighbor performed as the best model in terms of accuracy for a single-output model while artificial neural network algorithm showed the best overall performance for the integrated building and transportation energy use modeling.
