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...

Large scale building simulation

1771-TRP, Energy Modeling of Typical Commercial Buildings in Support of ASHRAE Building Energy Quotient Energy Rating Program

The objective of this research is to reconcile the differences between the empirical and modeled baselines for energy performance comparison for new and existing commercial buildings, allowing seamless translation of building energy performance metrics among LEED, Standard 90.1, Standard 189.1, Standard 100, and the bEQ As Designed and In Operation...

How GPU acceleration works

High Performance Building Simulation on Heterogeneous Platforms

Powerful computational capabilities have always been sought after by those working in fields that require vast amount of calculations to be done in a relatively short amount of time and a low cost. To meet this needs, we are conducting research in performing high performance building simulation using multi-core CPU...

Modelica diagram of the coupled airflow simulation

Coupled Simulation of Indoor Environment, Envelope, HVAC, and Control Systems

This research is to create a coupled simulation of indoor environment, envelope, HVAC and control systems to support the controls design and evaluation of energy efficient ventilation. The fast fluid dynamics (FFD) model is adopted to model the indoor environment with stratified air distribution. The Modelica Buildings library is used...
