Building Energy Models for Commercial Buildings Based on CBECS Data

March 11, 2021

As an outcome of ASHRAE RP-1771 , we have developed building energy models based on Commercial Buildings Energy Consumption Survey (CBECS) data to sup port the development of the ASHRAE building energy quotient (bEQ) standard. These building energy models can be used as a starting point to reconcile the differences...


Fast Fluid Dynamics Model

Nov. 11, 2020

Originating from the computer game industry, Fast Fluid Dynamics (FFD) is a faster alternative to Computational Fluid Dynamics (CFD) used for fluid flow simulation. Dr. Zuo developed the FFD model for indoor environment modeling in his Ph.D. thesis " Advanced Simulations of Air Distributions in Buildings " at Purdue University...

SCC Modeling Framework

Smart and Connected Community (SCC) Library

March 23, 2019

This open source Modelica library contains an integrated modeling framework and component models for designing coupled energy, transportation, and communication systems. The framework features a multi-level, multi-layer, multi-agent (3M) approach in order to enable flexible modeling of the interconnected systems. Various component and system-level models are included as the testbed...


Net Zero Energy Community (NZEC) Library

March 23, 2019

A open source Modelica library for the NZEC is built to facilitate the design and operation of a real NZEC. Using this library, a virtual testbed is built based on Historic Green Village, a real-world NZEC on Anna Maria Island, Florida. The testbed consists of a framework and system models...
