... Furthermore, the issue of energy-efficient and environmentally friendly buildings was also addressed in the National Academy of Engineering's report entitled, The Grand Challenges for Engineering in the chapter "Restore and Improve Urban Infrastructure." One technology that can support addressing this grand challenge in engineering is the predictive multiscale modeling of transport processes in and around buildings. Contemporary approaches to multiscale modeling of buildings in urban settlements are limited to isolated case studies on energy consumption of building systems and resultant projected CO2 emissions.

... The connection among all of these disparate fields of study is the universal system of transport equations solved numerically for appropriate temporal and spatial scales. The solution of transport equations typically includes mass and momentum equations to solve the airflow field, while the addition of partial differential equations to represent scalars, such as temperature and contaminant concentrations, or solid phase for particles are problem specific.

... In the next couple of decades, it is expected that with ever-increasing numbers of buildings and renovations of existing structures, the impact on augmenting local microclimates will be on the order of a 103-meter radius, which will also amplify large-scale transport processes in the boundary layer and lower troposphere. Therefore, buildings should not be simulated based on past climatic conditions, and sustainable building design concepts have to be conceptualized on much larger spatial and temporal scales than the comparatively miniscule footprint of a single building and its associated annual energy consumption.
