Located in Tropical climate, buildings in Miami requires cooling around the year. Space conditioning and domestic hot water systems account for 41% of all energy usage in a hotel. To save the energy for space cooling and domestic hot water heating, we proposed a heat recovery system which pre-heats the city water using the waste heat from space cooling. We also proposed to collect, store and process the rain water for non-portable usage. The system is implemented at the Grand Beach Hotel in Miami Beach, FL. This is a joint project with UCI Engineering.

Model Predictive Control for Chilled Water Plants

Model Predictive Control for Chilled Water Plants Anonymous (not verified) Thu, 01/01/2015 - 00:00

Improving the energy efficiency of chilled water plants is important since they account for about 35% the energy consumed by commercial building cooling equipment in the U.S. Model predictive control is a feasible way to enhance the operational efficiency of the chilled water plants. Our research is to develop a Python-based dynamic optimization platform that can perform continuous optimization for various control settings of chilled water plants. By using the Modelica modeling language, we can quickly model a chilled water plant with any system configurations and dynamically simulate its control behavior.
