Modernizing Cities via Smart Garden Alleys with Application in Makassar City

July 17, 2020

This project is sponsored by the National Science Foundation and is in collaboration with the US Department of State, Virginia Tech, and Gadjah Mada University. This project will work to integrate innovations in smart and connected communities with creative gardens within the city alleys of Makassar City, Indonesia. Collaborators: US...


Support for District Energy Simulation with Modelica

June 12, 2019

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 remains underutilized, particularly in the United States...


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...


Building Energy Modeling - OpenStudio SDK Development and Management

Feb. 14, 2019

In support of DOE’s Building Energy Codes Program, Pacific Northwest National Laboratory (PNNL) developed a suite of prototype building models representing newly constructed commercial buildings that comply with ASHRAE Standard 90.1 and IECC requirements. In this project, we will collaborate with PNNL on developing and improving the OpenStudio versions of...

Building to grid integration

Comprehensive Pliant Permissive Priority Optimization

Jan. 13, 2019

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...

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...

CRISP Type 1/Collaborative Research: A Human-Centered Computational Framework for Urban and Community Design of Resilient Coastal Cities

The goal of this research is to create new paradigms for the resilient design of urban communities, and uniquely tailored toward the design of coastal cities, thus contributing to NSF's science and engineering mission. By bringing together an interdisciplinary set of collaborators from engineering, architecture, and social sciences, this research...

DOE data center

Improving Data Center Energy Efficiency through End-to-End Cooling Modeling and Optimization

We developed an open-source, free software package (see the following links) which provides practical, end-to-end (from the IT equipment to heat rejection to the ambient) modeling and optimization for data center cooling. It can be used as a stand-alone tool by data center designers, service consultants and facility managers, or...

Smart and connected communities

BIGDATA: Collaborative Research: IA: Big Data Analytics for Optimized Planning of Smart, Sustainable, and Connected Communities

The goal of this project is to develop a new planning framework for smart, connected and sustainable communities that allows meeting such zero energy, zero outage, and zero congestions goals by optimally deciding on how, when, and where to deploy or upgrade a community's infrastructure. By bringing together interdisciplinary domain...
