Anatomy of a Real Time Building Energy model

When the “Oil Embargo” of 1973 occurred, I was a member of a small group of computer simulation engineers at Texas Instruments Inc. (T.I.) designing and evaluating military systems via computer simulations. The modeled systems included the Shrike missile, laser guided systems, and anti-tank missiles. The oil embargo occurred the fourth quarter of 1973 and in 1974 (T.I.) gave me the task of modeling the energy consumption of (T.I.) buildings and processes for the purpose of defining what could be done to reduce energy consumption. I used building energy computer programs available at the time that were based on simulating the yearly energy use of a building based on utility bills. I became convinced that a 24-hour real-time model was needed3. On retiring I decided to see if I could develop a model based on basic thermodynamic equations1,2 and perhaps develop a real time model7,8,9. This effort has resulted in the System Energy Equilibrium (SEE) Model summarized by this paper.

Best regards to all,

“Prescription for Chiller Plants” Analyzed with (SEE) Model

The (SEE) Chiller Plant Model is used to evaluate the Chiller Plant described by an ASHRAE Journal article of June 2006 by Baker, Roe, & Schwedler. The System Energy Equilibrium (SEE) Plant Model found that the control strategies used on the plant were good but could be better. Go to link below to view 72 page analysis.
