Paper 4 . Robison and Reichmuth, "Billing Simulation Tool for Performance Measurement and Verification", describes methodology for precision of engineering estimates, 2000. .

Paper 3 . Robison and Reichmuth, "Use of Billing Simulation Tool for Commissioning", presents several examples of using EZ Sim to estimate and verify savings or diagnose savings opportunities, 1999.

Paper 2 . White and Reichmuth, "Simplified Method Of Predicting Building Energy Use In Complex Buildings", describes engineering methodology for the monthly simulation, 1996.

Paper 1 . Robison and Reichmuth, "Short Term Monitoring", describes methods for collecting on-site measurements for model parameters. These measurements are supplemental and by no means required to use EZ Sim, 1990.
