Figure 8
The flowchart presents a structured process for validating a building energy simulation model. At the top, four stacked parallelogram shapes are labeled “Measured Data”. “Obtained Data”. “Weather Data”. and “Input Data”. arranged from top to bottom. A downward arrow from “Input Data” leads to a central rectangular box labeled “Building Energy Simulation (B E S)”. On both the left and right sides of the “Building Energy Simulation (B E S)” box, rectangular boxes labeled “New Set of Parameters” are connected by horizontal arrows pointing toward and away from the central box, indicating iterative parameter adjustment. From the bottom of the “Building Energy Simulation (B E S)” box, two vertical arrows lead downward to two separate parallelogram boxes. The left box is labeled “End-use Energy Simulation Results”. and the right box is labeled “Indoor Temperature Simulation Results”. Below the left results box, a diamond-shaped decision box is labeled “Output-Energy Bill Comparison”. From this decision box, a left-pointing line labeled “Non-acceptable Error Rate” leads back toward the left-side “New Set of Parameters” box. A downward line labeled “Acceptable Error Rate” leads to a rounded rectangle at the bottom center labeled “Validated Simulation”. Below the right results box, another diamond-shaped decision box is labeled “Output-Measured Temperature Comparison”. From this decision box, a right-pointing line labeled “Non-acceptable Error Rate” leads back toward the right-side “New Set of Parameters” box. A downward line labeled “Acceptable Error Rate” also leads to the same bottom rounded rectangle labeled “Validated Simulation”.Calibration process
