MEC supports two types of baseline models for each meter, used for different types of reporting.
Default Baseline Model
Each meter has a single Default Baseline Model used for Performance reporting. Performance reporting is central to traditional energy accounting, comparing energy performance during the report period to energy performance during a fixed baseline reference period. It is used to answer the question "Are my buildings performing better than they were during the baseline reference period, factoring out the effect of changes like weather?"
System-Generated Baseline Models
ManagingEnergy also provides Weather-Normalized reports, which allow users to compare weather-normalized energy performance among facilities over any time period. Where standard Performance reporting compares the present to the past, weather-normalized reporting is more flexible.
Weather-Normalized reporting requires several consumption models for each meter; one for each calendar year and each fiscal year. ManagingEnergy builds these "System-Generated" models automatically as soon as the consumption data is available. For example, if your organization's fiscal year ends in August, the system will add a new model when a meter reading is added that includes the last day of August. Suppose the reading is for Sept.7,2015, the model for FY2015 will be added to the meter. Similarly, calendar year models are added automatically when all of the December consumption data has been entered.
