Support for District Energy Simulation with Modelica

June 12, 2019

Sponsored by U.S. Department of Energy (DOE) CU East District Energy Plant District heating and cooling (DHC) systems commonly involve a central plant that distributes steam, hot water, or chilled water to buildings by means of insulated pipes. This is a promising and long-established solution for community sustainability, yet it...


Virtual Electric Power Board (EPB)

June 11, 2019

The goal of this collaborative research, with ORNL (who is the overall project lead) and the Electric Power Board (EPB) of Chattanooga, is to create calibrated virtual models of buildings within a utility’s service area to enable advanced grid modeling research (AGMR) integration with utility business systems. This will be...

This project is funded by Department of Energy and is a joint project with Pacific Northwest National Laboratory and Oak Ridge National Laboratory. The project goal is to develop a framework to prioritize behind-the-meter end-use resources, and a prototype tool that offers assessment of end-use load-utilization patterns and provides real-time...


An Innovative Computational Platform for Robust and Optimal Operation of Renewable Energy Cities

Nov. 24, 2018

As international sustainability goals and U.S. sustainability initiatives increase, sustainable energy applications are evolving from the conventional single building to the entire city. A 100% renewable energy city (REC) will undoubtedly play a pivotal role in this progression. The energy system of a REC will integrate many subsystems including renewable...

A modern chilled plant in HVAC system

1661-TRP, Development of Near-Optimal Control Sequence for Chiller Plants with Water Side Economizer using Dynamic Models

A water-side economizer (WSE) is a cooling system by which the chilled water is cooled by the cooling tower directly/indirectly without the use of mechanical cooling. Employing WSEs can decrease the building energy consumption by reducing the chiller operating time or increasing the chiller efficiency. WSEs, however, may pose challenges...
