Prerequisites 

Corequisite: ENME 332
Recommended: ENME 423

Description 

Urban microclimate from the perspective of transient heat and mass transfer using building energy simulations for building clusters as well as LEED building certification criteria. The focus is on understanding building energy consumption and environmental impacts from the individual building scale to a neighborhood scale.

Goals 

This course examines urban microclimate from the perspective of transient heat and mass transfer using building energy simulations for building clusters. The focus is on understanding building energy consumption and environmental impacts from the individual building scale (~100) to a neighborhood scale (~103). Emerging morphological properties of building clusters modulate transient convective and radiative heat transfer resulting in different local microclimatic conditions. At the neighborhood scale, these conditions are analyzed using heat and mass transfer simulations in building clusters to provide boundary conditions for transient building energy simulations. At the individual building scale, besides the energy consumption, this course examines connection between indoor and outdoor environments.

The students will be able to deploy the total surface energy balance equations for urban microenvironments. Furthermore, they will be able to explicitly solve the system of energy balance equations for simplified case studies. Finally, the students will be able to solve a system of energy balance equations for buildings in urban environments using modern numerical simulation techniques and tools. In the process, they will be able to define most important boundary conditions for solving such a system of equations, exemplified by campus building case studies.
