Energy use in existing buildings is most often related to influencing variables, such as ambient temperature, solar radiation, humidity and occupant schedules. Unfortunately, during the process of calibrating a simulation to an existing building's energy use, the simulator needs to quickly and easily determine whether a misbehaving model is due to adjustment in factors relating to temperature, time-of-day, humidity or other unknown parameters. Most often simple graphs of an existing building's energy use are compared to similar parameters from the simulation. Examples include time series, line graphs, scatter plots, horizontal and vertical bar charts, pie charts and most recently 3-D surface plots. Unfortunately, many of these graphic formats fail to produce meaningful graphs when overwhelmed by more than 8,000 data points on a plot. In addition, many of the graphs found in the ASHRAE Transactions from the 1950s to the present suffer from one or more graphical errors that can make a graph hard to read, or worse, misleading. This presentation reviews graphical presentation do's and don'ts, and presents several advance graphical display techniques that combine statistics and animations to more effectively display useful comparisons between actual and simulated data to assist the calibration process.
