This package is an outcome of our data center project sponsored by the DOE. See this research page for more information.

Modelica models package for data center cooling systems

4 system models and 30+ component models for data center cooling systems have been released in the DOE’s Modelica Buildings library (V5.0.0): Buildings.Applications.DataCenters.

ISAT-FFD model for data center airflow management

ISAT-FFD is a reduced order model trained by FFD simulations that can be used for fast predictions of airflow in the building.

Integrated model of data center airflow management and cooling systems

The integrated model that couples Modelica cooling system model with ISAT-FFD for airflow mangement, which can be regarded as an alternated detailed room model in Modelica Building library.

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

Improving Data Center Energy Efficiency through End-to-End Cooling Modeling and Optimization Anonymous (not verified) Sat, 10/01/2016 - 00:00

Led by Dr. Zuo, this is a joint research project with Lawrence Berkeley National Laboratory and Schneider Electric. We have 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 be integrated into existing data center management software for autonomous optimal operation. It is the first practical tool that couples the modeling of airflow-management and cooling systems to enable a global data center cooling optimization. Its self-learning regression model enabled by an in situ adaptive tabulation algorithm and a fast fluid dynamics model can predict the critical airflow information under various operational conditions within a few milliseconds. The equation-based modeling language allows a fast and flexible modeling of various cooling system configurations. We have demonstrated the usage of our tool and identified 53% energy saving potentials in a Florida data center and 74% in the Massachusetts data center.

Open Source Models for Data Center Cooling

This project has resulted in open source Modelica models for the data center cooling system. The models haven been released as a part of the DOE's open source Modelica Buildings library: http://simulationresearch.lbl.gov/modelica/releases/latest/help/Buildings_Applications.html#Buildings.Applications.

The model development branch is at https://github.com/lbl-srg/modelica-buildings/tree/master/Buildings/Applications.

This project has also developed a reduced order model “ISAT-FFD” trained by simulations in Fast Fluid Dynamics to predict airflow in data centers: https://github.com/doetools/isat_ffd.

See this page for more information on FFD.

The development site of the ISAT module in Modelica Buildings library is at: https://bitbucket.org/sbslab-zuo/datacenter-mblisat.

The ISAT data center case can be found at: https://bitbucket.org/sbslab-zuo/datacenter-isat-examples/src/master/.

Commerical Tool

Based on our open source FFD models, Schneider Electric developed a commerial software "EcoStruxure IT Advisor CFD", which is a cloud-based data center CFD design software.
