Abstract

The interactions between urban infrastructures, the inhabitants of the urban area, and the natural environment are driven by socioeconomics, thermodynamics, and other well-modeled processes. The symbiosis between cities and people have been limited to generalized assumptions about the energy patterns of various types of choices, such as space usage in building energy models, or even more general assumptions about the decision-making of individuals regarding choice of transit options. 
Urban systems—cities and the surrounding metropolitan areas—are complex systems that are, themselves, components of complex components, each operating at multiple spatial and temporal scales. There are fundamental research questions related to cities that can only be answered through a better understanding of the functioning of these components and their interactions. One way to achieve this goal is to develop a computational model of the urban environment that couples together the multiscale models of each of these subsystems, all the while collecting the data needed to inform as well as validate the model.
 
Current practice focuses primarily on modeling individual urban systems, for instance transportation, energy, ecosystems, water, or the urban atmospheric boundary layer, with most of these computational models developed in the context of a paucity of measurements and with a varying degrees of uncertainty, particularly where human activities are relevant. To adequately describe individual urban components it will be necessary to calibrate and validate these models with new data sources, some of which are only recently becoming available (e.g., open urban data about infrastructure specifications and operation) and some are rapidly emerging (instrumented cities through Internet-of-Things technologies). 
 
This talk discusses couplings pertaining to the weather, transportation and socioeconomics, and building energy modeling components of multi-scale urban integrated framework focusing on. In particular, the talk will focus on city population distributions as agents, their economic activity, how agents choose their mode of travel, travel simulation in an urban area, how agent arrival impacts building energy use, and how these activities affect urban microclimate and building energy use.
