My research interests include the theory of cooperative control in multi-agent systems as applied to building efficiency control: Development of methods for the control of energy flow in buildings, as enabled by cyber infrastructure. A significant novelty of this project lies in a fundamental view of a building as a set of overlapping, interacting networks. These networks include the thermal network of the physical building, the energy distribution network, the sensing and control network, as well as the human network. This work thus seeks to develop methods for simulating, optimizing, modeling, and control of complex, heterogeneous networks, with specific application to energy efficient buildings. Developments in the areas of cyber physical and microgrid systems present an enormous opportunity to substantially increase energy efficiency and reduce energy-related emissions in the commercial building energy sector.
