Commercial buildings are responsible for a significant fraction of the energy consumption and greenhouse gas emissions in the U.S. and worldwide. Consequently, the design, optimization and control of… (More)

We introduce improved reduced-order models for turbulent flows. These models are inspired from successful methodologies used in large eddy simulation, such as artificial viscosity, applied to… (More)

Over the past decade, a number of approaches have been put forth to improve the accuracy of projection-based reduced order models over parameter ranges. These can be classified as either i.) building… (More)

In this paper we consider the problem of best sensor location for optimal state estimation for real time energy efficient optimal control. Although the basic idea can be applied to the joint sensor /… (More)

We discuss four metrics for determining sensor placement in energy efficient building design. These include the norm of the observer gain, the trace of the observer Riccati solution, the distance to… (More)

This paper considers the problem of controlling a von Kármán vortex street (periodic shedding) behind a circular cylinder using cylinder rotation as the actuation. The approach is to linearize the… (More)

We introduce new boundary conditions for Large Eddy Simulation. These boundary conditions are based on an approximate deconvolution approach. They are computationally efficient and general, which… (More)

A drawback of using Chandrasekhar equations for regulator problems is the need to perform long-time integration of these equations to reach a steady state. Since the equations are stiff, this… (More)
